HSEB notes | Relation of biology with chemistry and physics

Biology has relation with different branches of science like physics and chemistry.

Relation of biology with Chemestry :

1. All living organism are made up of organic and inorganic compounds.
2. Molecules are broken down or synthesized in metabolic process involving chemical change.
3. Molecules move in and out of the cell through osmosis and diffusion.
4. Acid-base equlibrium in a cell maintains the PH of protoplasm for peoper functioning.

Relation of biology with physics :

1. Vision of object by our eye are due to presence of light.
2. Study on structure and functioning of human eye requires the knowlede of optics.
3. The various instrument which are used for biological reasearch and medical treatment like microscope, x-ray, ct-scan machine etc are based upon physical principals.
4. Light induces different pattern of response in lining organism like photosynthesis.
