What is the structure of the 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 fenestration in Golgi apparatus?

There is a gradation in the degree of cisternal fenestration within a Golgi complex. Cisternae at the convex pole are highly flattened and contain few pores, but those near the concave side are distended and exhibit a large number of roughly circular fenestrations 300–600 Å in diameter.

What is Golgi complex PPT?

 Also known as Golgi complex, Golgi body or Golgi.  Membrane bound organelles, which are sac-like.  Found in cytoplasm of most eukaryotic cells and absent in prokaryotes, Mammalian RBCs and sperm cells of bryophytes.

What is Golgi apparatus function?

The Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs, and is also called a Golgi body, Golgi complex, or dictyosome. The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell.

What are the four functions of the Golgi apparatus?

In general Golgi complex is of vital importance and serves many functions:

Absorption of compounds:
Formation of secretory vesicles and secretion:
Helps in enzyme formation:
Production of hormones:
Storage of protein:
Formation of acrosome:
Formation of intracellular crystals:
Milk protein droplet formation:

What is a fenestrated wall?

Fenestrated walls, also known as fenestrated planes, are used as a kind of video surveillance utilized in Derse. They consist of a wall panel made up of four separate windows used to show events elsewhere – these walls can be broken, and entered.

What is Fenestra in biology?

noun, plural fe·nes·trae [fi-nes-tree]. Anatomy, Zoology. a small opening or perforation, as in a bone, especially between the middle and inner ear. Entomology. a transparent spot in an otherwise opaque surface, as in the wings of certain butterflies and moths.

What is a Golgi apparatus function?

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. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
