Question

Give an account of Ultra structure of golgi complex.

Answer 1

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.[1] It was identified in 1897 by the Italian scientist Camillo Golgi and named after him in 1898.[2]

Components of a typical animal cell:

Nucleolus

Nucleus

Ribosome (little dots)

Vesicle

Rough endoplasmic reticulum

Golgi apparatus (or "Golgi body")

Cytoskeleton

Smooth endoplasmic reticulum

Mitochondrion

Vacuole

Cytosol (fluid that contains organelles, comprising the cytoplasm)

Lysosome

Centrosome

Cell membranePart of the endomembrane system in the cytoplasm, the Golgi apparatus packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination. The Golgi apparatus resides at the intersection of the secretory, lysosomal, and endocytic pathways. It is of particular importance in processing proteins for secretion, containing a set of glycosylation enzymes that attach various sugar monomers to proteins as the proteins move through the apparatus.

Answer 2

The complex was discovered by Camillo Golgi in 1898. Golgi, who worked at Pavia, Italy, was ignored. His discovery was said to be dirt on his lenses. Years later, electron microscope pictures showed structures just like in the original Golgi drawings. It is made of several flattened sac-like membranes which look like a stack of pancakes.
