Question
Answer in detail.
How all the life processes contribute to the growth and development of the body?
Solution
Life processes are processes which are required to maintain body functions and are necessary for survival. The important life processes are nutrition, transportation, metabolism, reproduction, respiration, and excretion. All these processes work together and result in the growth and development of the body. For example, nutrition is the process by which we take up nutrients which are used by the cells to meet their respective needs. This is a vital process which helps living beings to obtain their energy from various sources. Respiration is associated with the exchange of gases as well as burning of food. It results in the breakdown of glucose and release of oxygen. Similarly, cell cycle and cell division play an important role in the growth and development of the organisms. They help in the formation of new organisms as well as repair of dead and damaged cells and tissues.
