Control and Coordination is that some of the very important chapters of class 10 Science, for which it talks about how organisms control and coordinate their internal systems. It contains complex processes of the nervous system, hormonal control, and the response of both humans and plants to stimuli. Taking knowledge about how signals are transmitted in the body, the role of the brain and spinal cord, as well as how hormones affect different operations of the body will be mandatory for good foundational backbone building in biology.
We have collected 25 core MCQs that Class 10 students can use to test their knowledge regarding this subject in the following blog post. The question bank includes all the important concepts – from the structure of neurons and the role of hormones in regulating various functions of the body to how plants respond to their environment. Whether you need to study for some exams or want to strengthen your learning, these MCQs will help you steer in the right direction toward mastering the chapter on Control and Coordination.
