Relation of Biology with Physics

a. Light:

It is studied in physics but light is important for photo systhosis which is biological pheromenon. Therefore to understand photosysnthesis we should know about light.

b. Temperature:

It is physical factor. It helps in growth development, metabolism seed germination etc.

c. Energy:

Very essential for life activities. It is stored in cell in the form of ATP. But it is studied in physics.

d. Force:

Cohesive force (attraction force between same motechles) and Adhesive force lattraction force between different molecules are essential for water conduction and transportation of substances in body.

Relation of Biology with Chemistry

  1. Body of organisms is made up various organic and inorganic molecules.
  2. There should be knowledge of chemical reaction to understand of biological processes.


  1. Hormones enzymes, vitamins, antibiotics drugs are chemical.
