Cells were discovered in 1665 by British scientist Robert Hooke.Animal and plant cell range in size between 1 and 100 micrometers and are thus visible only with the aid of a microscope.

GOLGY BODYGOLGY BODY

The Golgi apparatus is the distribution and shipping department for the cell's chemical products.

It modifies proteins and fats built in the endoplasmic reticulum

and prepares them for export to the outside of the cell.

Function

The main function of these micro bodies is digestion.

Lysosomes break down cellular waste products and debris from outside the cell into simple compounds, which are transferred to the cytoplasm as new cell-building materials.

- a single layer of unit membrane enclosing fluid in a sack

Function - produces turgid pressure against cell wall for support    - stores water and various chemicals    - may store insoluble wastes
