Discuss in detail about the physical properties of protoplasm.

Explanation

1. Protoplasm is translucent, odourless and polyphasic fluid.
2. It is a crystal colloid solution which is a mixture of cheimcal substances forming crystalloid and colloidal solution.
3. Protoplasm exhibits three Brownian movement, amoeboid movement and cytoplasmic streaming or cyclosis. Viscosity of protoplasm is 2-20 centripoises. the refractive index of the protoplasm is 1.4.
4. The pH of the protoplasm is around 6.8, contain 90% water (10% in dormant seeds).
5. Approximately 34 elements are present in protoplasm but only 13 elements are main or universal elements i.e., Ch,H,O,N,Cl, Ca,P,Na,K,S,Mg,I and Fe. Carbon, Hydrogen, Oxygen and Nitrogen form the 96% of protoplasm.
6. protoplasm is neither a good nor a bad conductor of electricity.
