CYTOPLASM

A cell typically consists of membrane bound cell organelles and nucleus in it. These cell organelles float in a jelly like substance called as cytoplasm.

When we remove the outer membrane and the nucleus from a cell, we are left with cytoplasm.

• Cytoplasm was discovered by Kolliker in 1862.

• It is the site of both biosynthetic and catabolic pathways.

Further if we remove all the organelles from a cytoplasm, we get cytosol.

So, cytoplasm can be divided into two parts: cytosol and cell organelle.

(i) Cytosol: Aqueous soluble part contains various fibrous proteins forming cytoskeleton.

(ii) Cell organelles: Living part of the cells having definite shape, structure and function bounded By Plasma membrane. It is also known as Trophoplasm. It is a micromolecular substance and it consists of the following types :

1. Endoplasmic reticulum
2. Mitochondria
3. Golgi complex
4. Ribosome
5. Vaculoes
6. Lysosome
7. Plastids
