NCERT Exemplar Solution for Class 10 Science Chapter-7 Control and Coordination
Control and Coordination is one of the most interesting chapters in Class 10 Science because it explains how living organisms respond to changes around them. The chapter focuses on the nervous system, hormones, reflex actions, and coordination in plants and animals. Students learn how different organs and systems work together to maintain balance and proper functioning in the body. This chapter builds a strong foundation in biology by connecting scientific concepts with daily life activities such as movement, thinking, and reactions. The NCERT Exemplar Solution for Class 10 Science helps students understand difficult concepts through advanced questions and detailed explanations. The NCERT Exemplar Solution also improves logical thinking and analytical skills, while NCERT solutions for class 10 support complete preparation for examinations with concept-based learning.

Nervous System and Coordination in Human Beings
The nervous system is the control center of the human body. It receives information from the surroundings, processes it, and sends responses to different organs. The chapter explains the structure and functions of neurons, brain, spinal cord, and nerves in a simple and systematic manner. Students understand how messages travel through electrical impulses and help the body react quickly.
The brain is divided into different parts, each performing specific functions. The forebrain controls thinking, memory, and voluntary actions. The midbrain and hindbrain coordinate balance, heartbeat, and involuntary activities. Reflex action is another important topic discussed in this chapter. Reflexes are quick automatic responses controlled by the spinal cord without involving conscious thinking. Students also study receptors and effectors, which play an important role in detecting changes and producing responses. Exemplar questions from this section usually focus on diagrams of neurons, reflex arcs, and functions of different parts of the brain. Practicing these questions helps students improve conceptual understanding and scientific explanation skills.
The NCERT Exemplar Solution for Class 10 Science Chapter-7 Control and Coordination provides detailed answers that make complicated biological processes easier to understand. It also prepares students for application-based and reasoning questions in board examinations.
Hormonal Coordination and Endocrine System
Apart from the nervous system, the body also uses hormones for coordination. Hormones are chemical messengers secreted by endocrine glands. These chemicals regulate growth, metabolism, reproduction, and many other body functions. The chapter explains important glands such as the pituitary gland, thyroid gland, pancreas, adrenal gland, and reproductive glands.
The pituitary gland is known as the master gland because it controls the activities of other endocrine glands. Students learn about the role of insulin in controlling blood sugar levels and the importance of thyroxine in metabolism. The chapter also explains hormonal imbalance and its effects on health. Chemical coordination through hormones is slower than nervous coordination but lasts longer. Exemplar exercises often include comparison-based questions between the nervous system and endocrine system. These questions help students understand the differences in speed, method, and duration of control mechanisms.
The chapter further explains adolescence and hormonal changes during growth. This makes the topic practical and relatable for students. By solving exemplar questions regularly, learners develop confidence in answering diagram-based and conceptual biology questions effectively.
Coordination in Plants and Importance of Exemplar Questions
Plants do not have a nervous system, yet they respond to environmental changes through movements and hormones. The chapter explains plant movements such as phototropism, geotropism, hydrotropism, and thigmotropism. Students learn how plants react to stimuli like light, gravity, water, and touch.
Plant hormones such as auxins, gibberellins, cytokinins, and abscisic acid are discussed in detail. These hormones regulate growth, seed germination, flowering, and other plant activities. The chapter shows how plants coordinate their activities without a brain or nerves. Exemplar questions from this section improve observation and analytical skills. Students practice identifying types of plant movements and understanding hormonal functions. These exercises also help in preparing for competency-based questions in school examinations.
One major advantage of studying exemplar solutions is the development of scientific thinking. The solutions provide accurate explanations, diagrams, and reasoning that help students understand the logic behind every answer. Regular revision of exemplar exercises strengthens memory retention and improves exam performance. This chapter is highly scoring when concepts are understood clearly. Students who revise the nervous system, hormones, and plant coordination systematically can answer both short and long questions with confidence. The combination of theoretical knowledge and practical examples makes this chapter highly engaging and useful for future science studies.
