FAQs on Control & Coordination : NCERT Solution, Class 10 Science

1. What is the role of control and coordination in living organisms?
Ans. Control and coordination play a crucial role in living organisms as they help in maintaining homeostasis, responding to external stimuli, and allowing proper functioning of different body systems. It involves the integration of various sensory inputs, processing of information, and generating appropriate responses to maintain an internal balance.
2. How does the nervous system help in control and coordination?
Ans. The nervous system is responsible for control and coordination in the body. It consists of specialized cells called neurons that transmit electrical signals or nerve impulses. These impulses travel through the nerve cells to different parts of the body, allowing communication between various organs and tissues. The nervous system helps in responding to stimuli, coordinating movements, and maintaining body functions.
3. What are the different types of coordination in living organisms?
Ans. There are two main types of coordination in living organisms: nervous coordination and chemical coordination. Nervous coordination involves the transmission of nerve impulses through the nervous system, which allows quick and immediate responses to stimuli. Chemical coordination, on the other hand, involves the release of hormones by endocrine glands into the bloodstream. These hormones travel to target cells or organs and regulate various bodily functions over a longer duration.
4. How does the human brain control and coordinate various activities of the body?
Ans. The human brain is the control center of the body and coordinates various activities through the nervous system. It receives sensory information from different parts of the body, processes it, and generates appropriate responses. The brain consists of different regions that are responsible for specific functions such as memory, speech, motor control, etc. These regions communicate with each other and with the rest of the body through nerve impulses, ensuring proper control and coordination.
5. What happens when there is a disruption in control and coordination in living organisms?
Ans. Disruption in control and coordination can lead to various issues in living organisms. It can result in impaired sensory perception, loss of motor control, difficulty in maintaining homeostasis, and altered physiological functions. For example, disorders like Parkinson's disease, Alzheimer's disease, or hormonal imbalances can affect the control and coordination systems, leading to symptoms like tremors, memory loss, or irregularities in body functions. Timely diagnosis and appropriate treatment are necessary to restore normal control and coordination.
