What is the structure and function of Golgi apparatus?
What is the structure and function of Golgi apparatus?
The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.
What is the function of Golgi body apparatus?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
What is the structure of a Golgi apparatus?
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
What is the function of Golgi apparatus PDF?
Secretion: It is the major function of Golgi apparatus, which help in collection, storage, condensation, modification and packaging of various materials into secretory vesicles.
What are the functions of Golgi apparatus Class 9?
Golgi apparatus helps in packaging and dispatching these materials to targets inside and outside the cell. Storage, modification and packaging of products are the main functions golgi apparatus which are happening in vesicles.
What is the function of the Golgi apparatus for kids?
The Golgi apparatus is an organelle that acts as the packaging center of the cell. It takes in protein, modifies it, and then places it in shipping containers called vesicles. The Golgi apparatus also makes lysosomes, which are organelles that contain digestive enzymes.
How the structure of the Golgi body enables it to perform its function?
The cisternae pouches in the various compartments of the Golgi body contain a special class of proteins called enzymes. The specific enzymes in each pouch enable it to modify the lipids and proteins as they pass from the cis face through the medial compartment on the way to trans face.
Who describe the ultrastructure of Golgi apparatus?
Ultrastructure of golgi apparatus : (1) Golgi apparatus was first recognized by Italian Physician Camillo Golgi (1898) in nerve cell of wild owl. (2) The structure of golgi apparatus appears to be complex.
What is the function and structure of Golgi bodies Class 9?
Golgi body is present in eukaryotic cells. It consists of many parallelly stacked disc-shaped sacs known as cisternae. The main function of the Golgi body is to package materials formed in the endoplasmic reticulum and transport in the form of vesicles within the cell or to be secreted outside the cell.
What is the structure of Golgi apparatus 9?
Golgi apparatus consists of a system of membrane-bound fluid-filled vesicles (flattened sacs) arranged parallel to each other. They arranged in the form of stacks called as cisternae. These cisternae are smooth and flattened in structure. Vesicles membranes have connections with the membranes of Endoplasmic reticulum.
Who discovered Golgi apparatus?
Camillo Golgi
The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as ‘the Golgi”, was first reported by Camillo Golgi in 1898, when he described in nerve cells an ‘internal reticular apparatus’ impregnated by a variant of his chromoargentic staining.
