What is control and coordination in biology?
Control is the power of restraining and regulation by which something can be started, slowed down or stopped. Co-ordination is the working together of various agents of the body of an organism in a proper manner to produce an appropriate reaction to a stimulus is called coordination.
What is the need for a system of control and coordination in an organism Class 10?
An organism needs control and coordination system for the following functions : (i) To save the body of the organisms from the harmful changes in the environment. (ii) To control the speed of voluntary and involuntary actions. (iii) To have the capability to think and learn for responding to any stimuli.
Why is a system of control and coordination essential in living organisms?
1)Control and coordination is required for survival of any organism. It is necessary for each biotic organism to obtain its nutrients and conditions to survive in which could be made possible with the presence of the control and coordination systems. Eg- If a plant is deprived of water most of the time.
How is control and coordination maintained in the human body?
In human beings, the control and coordination take place through the nervous system and the endocrine system that produce and secrete hormones. The five sense organs in our body, eyes, ears, nose, tongue and skin are called receptors and these organs functions by receiving information from the environment around us.
What is control and coordination in plants?
It is the plant hormones that promote its growth. The movement of plant parts is due to various stimuli like gravity, water, light, chemical, touch, etc. So, the function of control and coordination in plants is performed by the chemical substances called plant hormones or phytohormones.
Which organ systems help in control and coordination of the body?
The nervous system helps in controlling and coordinating different activities of the human body. There are three types of nervous systems in our body- cranial nerves, spinal nerves and visceral nerves. All these run through our body sending and receiving messages.
How is the coordination and organization of the body of an organism important?
The integrated activities of the organs in an organ system are required for the efficient functioning of that particular organ system. Similarly, when all organ systems function in an integrated and coordinated manner, then the survival of an organism is guaranteed.
What is control and coordination system?
How is chemical control and coordination done in living system?
Answer. Chemical coordination in human beings occurs through chemical messengers called hormones. Hormones are secreted by glands directly in blood stream to act at distant sites in the body (target organs).
Which organ system helps in control and coordination of the body?
Nervous system and endocrine system are responsible for control and coordination of complex, multicellular human body with multiple organ systems of complex functioning.
What is coordination in animals?
Coordination: The working together of various organs of the body of an organism in a proper manner to produce an appropriate reaction to a stimulus is called coordination.
How is control and coordination between environment and plants brought about?
Plants perform photosynthesis which is also dependent upon environmental factors. Light and gravity are the environmental triggers that influence the change in direction of the plant growth. This is known as tropism. It is internally controlled or coordinated by hormones.
