What is the need for a system of control and coordination in an organisms ?
solution:
Multicellular organisms have diverse structure and functions. There are different system which perform specific function but the functioning of one system is not independent from the other. There is integration of all functional acitivities of the organism. For example, digestive enzymes are secreted into the food canal only when there is a food.
The integration is possible because of communication and control. Communication makes control possible. The control and coordination occurs by two systems, i.e.,
(i) by the release of chemical messengers called the hormones from endocrine system
(ii) by the conduction of nerve impulse, i.e. nervous system.
