Answer:
Golgi Apparatus
Golgi apparatus(or complex, or body, or ‘the ‘Golgi’) is found in all plant and animal cells and is the term given to groups of flattened disc-like structures located close to the endoplasmic reticulum.
The number of ‘Golgi apparatus’ within a cell is variable. Animal cells tend to have fewer and larger Golgi apparatus. Plant cells can contain as many as several hundred smaller versions.
The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles. Depending on the contents these are despatched to one of three destinations:
Destination 1: within the cell, to organelles called lysosomes.
Destination 2: the plasma membrane of the cell
Destination 3: outside of the cell.
The name behind the apparatus
The Golgi apparatus is the only cell organelle to be named after a scientist. The visible characteristics of the organelle were first reported by Camillo Golgi (1843-1926) at a meeting of the Medical Society of Pavia on 19 April 1898 when he named it the ‘internal reticular apparatus’.
Debate about the existence of the apparatus continued even after 1913 when the term ‘Golgi apparatus’ was officially given to the ‘internal reticular apparatus’. It was not until 1954 that work in electron microscopy finally put the seal of approval on the existence of the organelle and the eponym ‘the Golgi’, was fully accepted.
