1. Respond to stimuli

The power to respond to stimulus is known as irritability. It may take place due to the change of both external and internal environment. For example, the leaflets of Mimosa pudica (sensitive plant) close up in pairs and droop down when touched.

2. Growth 

Young organisms grow in size and attain maturity. When the rate of anabolism exceeds the rate of catabolisms new organic substances are added to the protoplasm as a result the living cell increases in size and the organism grows.

3. Metabolism

In the protoplasm of a living cell many of the chemical reactions are always taking place. The changes that occur due to these reactions are required for the 1.1.1 Concept about Orig maintenance of body functions. The sum total of all these biochemical reactions taking place within a living cell is called metabolism.

4. Respiration

Respiration is an energy releasing biochemical process. Complex by experimental evidence performed organic food substances are oxidized with the liberation of energy, carbon dioxide and water. Potential energy stored within the food meterials is converted into kinetic form. This include chemical evolution and biol energy is utilized for different metabolic processes occurring in the body. Some amount of energy is stored within ATP molecules. Respiration is a continuous process which occurs throughout the life period of all living cells.

5. Energy utilization

Living beings continuously require energy to perform various essential for the formation of protoplasm. Hi activities of the body. Energy is obtained from food materials which is either manufactured formation amongst themselves. With gradual by the cells or acquired from outside
