Control Coordination in Plants and Animals

In the previous lesson, you read about life processes. While studying the life processes, we talked about various kinds of movement as a sign of life. While some of the movements are not perceptible to human eyes, some others are easily visible. While in a park, you can see various kinds of movements; like a child running after a ball, a squirrel scurrying through a bush, a pigeon flying, etc. What is interesting about all these movements is that none of the movements happens without a cause. Whatever movement an organism makes is in response to certain changes in its external environment. For example; children run because they enjoy playing. A squirrel runs to pick a peanut or to save its life. Whatever movement is made by an organism, it is done in order to get some benefit. For example; a seed shows movements during germination. The seedling moves up so that it can break the soil and can grow up to get sunlight and air. A lion runs after a deer in order to get food, while the deer runs away in order to save its life.

Proper control and coordination of various movements are required for an organism to survive. This is especially true for animals. E.g, a deer always keeps on hearing and looking for any sign of danger. It needs to run just in time, and in the right direction with sufficient speed; to save its life from a lion.

Even our internal organs need to have proper coordination in their movements. The heart needs to pump blood so that other organs can get oxygenated blood in time. The digestive system needs to properly digest the food so that other organs can get nutrition on time. The kidney needs to filter blood so that nitrogenous waste is removed in time.

Barring the simple animals; all other animals have a nervous system for control and coordination. The action of the nervous system is supported by the action of various hormones to facilitate control and coordination.

Plants also need to have control and coordination in their various activities; in order to show a timely response to external stimuli.

In this lesson, you will learn about the human nervous system and endocrine system. You will also learn about various kinds of movements in plants and about control and coordination in plants.
