Our body is made up of billions of cells that get organized into different tissues. Different tissues constitute organs, and different organs constitute systems such as the digestive, respiratory and circulatory systems.
In order to perform a particular function the component organs of each system depend on each other and work in harmony. In the absence of such working in harmony, an organism cannot do many things that it normally does.
For example, when we run, our muscles require greater energy, which can be produced when there is a greater supply of oxygen. To increase the oxygen supply, the rate of breathing increases. When we stop running, our muscles do not need so much energy. Consequently, there is no need for extra oxygen and the rate of breathing comes down to the normal level.
All these activities are coordinated and well organized. The working together of various systems in the body is called coordination.
Response and Coordination in Plants and Animals: The ability of an organism to detect changes and make appropriate responses is called sensitivity. Anything to which an organism responds and reacts is called a stimulus.
In animals the responses are quicker and more obvious. Unicellular animals respond to stimuli either by moving towards them or away from them.
In multicellular animals, the process of responding to stimuli is different. The responses occur within seconds, but through a complex network of communication which involves several life processes like movement, locomotion, transport, respiration, etc.
For example, when you step out in bright sunlight, you partly close your eyes to keep out the bright light. You may start sweating as the temperature rises.
These are coordinated responses to stimuli. Response and coordination in animals involve the sense organs, nervous system and chemical messengers called hormones.
Plants also react to specific environmental conditions. However, they have no nervous system and their responses are in the form of slow modified growth or movements called turgor movements, caused due to the distension swelling of cells.
Let us first examine the phenomena of response and coordination in plants.COORDINATION AND RESPONSE Posted by Pusat Tuisyen Bestari Ilmu Biology at Labels: Chapter 2 comments: Leslie Lim 26 June at I enjoy reading youor articles.

Essay about Coordination and response in plants 16w3gmz Q1.(a) When a seed starts to grow, the young root grows downwards towards gravity.
The young shoot grows upwards, away from gravity. The plants do not posses nervous system for the conduction of the impulse but still it shows immediate response to stimuli. The plant Mimosa pudica is well known for its rapid plant movement. In the evening the leaflets will fold together and the whole leaf droops downward.
