The Golgi complex, also known as the Golgi body, Golgi apparatus, or the Golgi apparatus, is a cellular organelle found in most eukaryotic cells. It is located next to the endoplasmic reticulum, near the nucleus, and is composed of stacks of flattened sacs known as cisternae.
The Golgi complex is involved in the sorting, packaging, and distribution of proteins and lipids throughout the cell. It is responsible for the synthesis of carbohydrates and glycoproteins, as well as for chemical modifications to proteins and lipids as they are translated into their functional forms.
The Golgi complex is also involved in the transport of these molecules out of the cell, either through the cell membrane or via exocytosis. The Golgi complex is composed of several membranes that are referred to as lamellar or cisternae and these cisternae are divided into the cis, medial, and trans compartments.
A Golgi complex consists of a membrane made up of phospholipids and proteins, as well as enzymes and enzymes that are embedded within its different cisternae.
Is Golgi complex in plant or animal cells?
The Golgi complex is found in both plant and animal cells, although there are a few differences between them. In plant cells, the Golgi complex is typically located at the base of the cell, forming a network of flattened and stacked membrane-bound compartments.
This structure helps to regulate the transport of proteins and other molecules to and from the cell. In animal cells, the Golgi complex is usually located at the cell’s center and it consists of a series of folded sacs, forming a flattened and branched structure.
In both cells, the Golgi complex serves as a central organelle for the sorting, processing, and packaging of molecules and other substances, such as proteins and hormones, that are secreted outside of the cell.
What cell does not have Golgi?
The Prokaryotic cell does not have a Golgi. Prokaryotic cells are made up of a single cell with no nucleus or other organelles. Instead, the various metabolic machinery of the cell is contained inside of the cytoplasm.
This means that the typical organelles found in eukaryotic cells, such as the Golgi and endoplasmic reticulum, are not present in a Prokaryotic cell.
What is not found in Golgi body?
The Golgi body, also known as the Golgi apparatus or Golgi complex, is a cellular organelle present in virtually all eukaryotic cells. It is made up of multiple stacks of flat, closely packed sacs or cisternae that are covered in associated proteins and enzymes.
While the Golgi body is involved in several cellular activities, from biosynthesis and membrane transport to glycoprotein modification and protein sorting, there are certain elements that are not found in this organelle.
These include ribosomes, vacuoles, histones, centrioles, and endoplasmic reticulum.
Is Golgi body absent in plant cell?
No, the Golgi body is not absent in plant cells. In fact, it is found in all eukaryotic cells, including those of plants. The Golgi body, also known as the Golgi apparatus or Golgi complex, consists of multiple membrane-bound compartments that store, modify, and package various molecules such as proteins, lipids, and carbohydrates.
It is important for the transport and sorting of molecules within the cell, and plays a role in a variety of cellular processes such as protein sorting, glycosylation, and lipid metabolism. In plant cells, the Golgi body is particularly important for synthesizing and storing proteins and other molecules that are necessary for cell wall formation, cell division, growth, and other essential cellular processes.
Why is Golgi apparatus not present in red blood cells?
The Golgi apparatus is an organelle found within cells that is responsible for a number of important functions, including packaging and modifying proteins, lipids, and carbohydrates. However, red blood cells (or erythrocytes) don’t actually possess a Golgi apparatus or any other membrane-bound organelles.
This can be attributed to the fact that the primary purpose of red blood cells is to carry oxygen and other molecules inside the body, and their lack of organelles allows them to maintain a simple, lightweight structure that is optimal for their transport functions.
Furthermore, since red blood cells lack a nucleus, as well as other organelles like mitochondria, they don’t require the Golgi apparatus for the same processes other cells would.
In addition, since red blood cells are considered to be a type of terminally differentiated cell, in which the cell has met its full potential, the presence of a Golgi apparatus would no longer be necessary.
As a result, many other terminally differentiated cells, such as hair and nail cells, also lack a Golgi apparatus.
In which cell mitochondria and Golgi complex are absent?
Cells that lack mitochondria and Golgi complex include red blood cells, bacteria, and some protozoans. These cells do not include a nucleus and lack the internal structures found in eukaryotic cells.
In red blood cells, mitochondria are absent as they are not needed for the primary role of these cells in transporting oxygen and carbon dioxide. As a result, red blood cells have no respiration process, and thus, no need for the energy produced by mitochondria.
Bacteria cells do not include a nucleus or mitochondria either. The membrane surrounding a bacterial cell is generally permeable and self-regulating and able to carry out simple metabolic processes. As a result, the need for mitochondria is not necessary.
Protozoans are single-celled organisms that move independently, and some lack mitochondria. The metabolic processes of these cells are closely related to those of bacteria, with genomes that lack the organization and expression processes seen in eukaryotic cells.
As a result, the need for the mitochondria or Golgi complex is not necessary.
In summary, cells that lack mitochondria and Golgi complex include red blood cells, some protozoans, and bacteria.
Which organism and cell Golgi apparatus is absent?
The Golgi apparatus is absent in some species of archaea and protists, such as methanogens and diplomonads, as well as some bacteria, such as magnetotactic bacteria. Studies show that the Golgi apparatus may not be necessary for the normal function of many single-celled organisms since they have adapted alternative mechanisms for various transport functions.
For example, in lieu of the Golgi apparatus, archaea have a non-membrane-bound organelle consisting of enzymatically active protein-sorting machineries, which are important for cellular processes such as protein folding and glycosylation.
These organisms have also been shown to lack vesicle formation and trafficking properties that are typically associated with the Golgi apparatus.
What is the function of Golgi bodies and their location?
The Golgi bodies, also known as Golgi apparatus or Golgi complex, are vital to the function of a cell. They are organelles found in both plant and animal cells and are made up of a series of flattened, membrane-bound sacs known as cisternae.
The Golgi bodies are located near the nucleus and where material is transferred in and out of the cell.
Their main function is to act like a post office within the cell, sorting and modifying proteins and lipids to be used for processes that occur within the cell, as well as for export. These proteins and lipids are transported in vesicles derived from the endoplasmic reticulum (ER).
The Golgi bodies add certain modifications to these proteins and lipids, such as attaching sugar molecules or changing their shapes. Once modified, the proteins and lipids are packaged into small vesicles which are then transported to their specific locations throughout the cell.
The Golgi bodies also aid in the production of lysosomes, which are essential for breaking down cellular waste and other materials. The Golgi bodies receive and transport vesicles containing the materials needed for lysosome formation, to the cell membrane for export out of the cell.
In conclusion, Golgi bodies are organelles found within both animal and plant cells, located near the nucleus for easy access. They perform the vital function of post office within the cell, sorting and modifying proteins and lipids for cell processes and export, and are also essential for the production of lysosomes.
Where are the most Golgi bodies found?
Golgi bodies, also known as the Golgi apparatus, are found in most eukaryotic cells. They are typically located near the cell nucleus in the cytoplasm, and consist of several flattened, stacked sacs called cisternae.
They are made up of numerous membrane-bound compartments, each playing a specific role in the packaging, sorting and transport of molecules produced by the cell. Golgi bodies are responsible for the formation of lysosomes and post-translational modification of proteins.
In plant cells, they are also involved in the production of cell walls. They are most abundant in secretory tissues, where they are found in large numbers, particularly in glandular and pancreatic cells.
However, they can also be found in all types of cells in the body, such as nerve, muscle, and epithelial.
What are the two places that the Golgi bodies send things?
The Golgi bodies, also known as the Golgi apparatus or Golgi complex, are organelles, or small organ-like structures, found within cells. They are part of the endomembrane system and are responsible for sorting, modifying, and packaging proteins and lipids into vesicles, which are then sent to their destination.
The two places to which the Golgi bodies send things are the lysosomes and the plasma membrane. Lysosomes are small, spherical organelles that are filled with digestive enzymes and play a role in intracellular digestion.
They are normally found within the cytoplasm and the proteins and lipids sent to them by the Golgi bodies are processed to be broken down and recycled.
The other destination is the plasma membrane, which is the thin, semi-permeable barrier that surrounds the cell and serves to keep the cell’s environment separate from the outside world. Proteins and lipids sent to the plasma membrane by the Golgi bodies are used in many cellular processes, including cell signaling, cell recognition, and cell-to-cell adhesion.
Where is the Golgi complex located and what goes on there?
The Golgi complex, also known as the Golgi apparatus or Golgi body, is a cellular organelle found in eukaryotic cells, including animal, plant, and fungal cells. It is located within the cytoplasm, where it lies near the endoplasmic reticulum.
The Golgi complex is a membrane-bound structure composed of a variety of distinct compartments, often referred to as cisternae, stacked one on top of the other, each varying in shape and appearance.
The Golgi complex is the site of several important biological processes and acts as a sort of cellular “post office. ” Molecules synthesized by the endoplasmic reticulum are transported to the Golgi complex, where they undergo further modification and packaging.
These modifications, facilitated by enzymes found within the Golgi complex, help determine where the molecule is sent within the cell, helping to ensure that it is delivered to the right compartment.
Additionally, the Golgi complex is involved in the production of lysosomes, an intracellular organelle responsible for the digestion of macromolecules, and in the secretion of proteins from the cell.
The Golgi complex also plays a role in the formation of specialized organelles – such as centrioles and flagella, and in the development of fungal spore coats.
What is the main function of Golgi complex?
The main function of the Golgi complex is to modify, sort, and package proteins and lipids that are synthesized by the endoplasmic reticulum and other cellular organelles for transport throughout the cell.
It is an organelle that is made up of several flattened vesicles that are stacked together and are involved in the modification, transport, and sorting of proteins and lipids. In addition to these tasks, the Golgi complex plays a key role in the secretion of cell products, distribution of newly synthesized membrane proteins, and formation of lysosomes and polysaccharides.
It helps to pre-package and target proteins and other molecules to various parts of the cell, such as the plasma membrane, lysosomes, and vacuoles. The Golgi complex also plays an important role in the biosynthesis of glycoproteins and glycolipids, the form of lipids in which carbohydrate is covalently attached to a lipid group.
These molecules serve important functions in the body, such as providing cell-cell recognition, protecting cells from damage, and providing structure to cells.
What 2 locations in the cell does protein synthesis occur?
Protein synthesis occurs in two locations within the cell: the nucleus and the cytoplasm. In the nucleus, the genetic information is stored in the form of DNA, which acts as the blueprint for the proteins that should be made.
This information is transcribed into messengers, known as messenger RNA (mRNA), which then exit the nucleus and move to the cytoplasm. Here it attaches to ribosomes and a group of proteins which are responsible for interpreting the information and creating the specific proteins as directed.
This process, known as translation, is the second stage of protein synthesis, where the mRNA is translated into a specific sequence of amino acids that, once linked together, form a protein.
What are 3 things the Golgi apparatus does for the cell?
1. The Golgi apparatus processes and packages macromolecules such as proteins and lipids that are synthesized by the endoplasmic reticulum. It modifies, sorts and then ships these substances to the locations in the cell where they are needed.
2. The Golgi apparatus also manufactures certain molecules of its own, such as glycoproteins and proteoglycans, which are critical components of the extracellular matrix that supports and protects the cell.
3. In addition, the Golgi apparatus is involved in the production of lysosomes and other organelles. It generates vesicles that transport molecules out of the cell and can also receive materials from other cells or from outside the cell itself.
