It explores how animals, particularly humans, use nervous and hormonal systems for rapid and sustained responses, and how plants coordinate their growth and development through chemical signals. Understanding these systems is fundamental to comprehending life processes. Key topics Living organisms need to respond to changes in their environment and coordinate their internal activities for survival. This involves receiving stimuli and generating appropriate responses. Example How a plant bends towards light (phototropism) or how an animal reacts to a sudden loud noise. Watch out Thinking that coordination only applies to complex animals with brains.

Tap the card for an example Example How a plant bends towards light (phototropism) or how an animal reacts to a sudden loud noise. Why it matters It ensures the organism's survival, adaptation, and efficient functioning in a dynamic environment. Watch out Thinking that coordination only applies to complex animals with brains. Ask at home Ask your child to give an example of how a plant or animal responds to something in its surroundings and why that response is important. This chapter introduces the concept of control and coordination as essential for the survival and efficient functioning of all living organisms. It details the human nervous system, comprising the central and peripheral nervous systems, explaining the structure of a neuron and the transmission of nerve impulses. Reflex actions and the reflex arc are discussed as rapid, involuntary responses. The chapter then transitions to chemical coordination in animals, describing the endocrine system, major endocrine glands, the hormones they produce, and their roles in regulating various body functions, including the crucial concept of feedback mechanisms. Finally, it covers coordination in plants, focusing on plant hormones (phytohormones) and their influence on growth, development, and responses to environmental stimuli like light and gravity, known as tropisms.

What you should learn Keep these close Control and coordination are essential for all living organisms to respond to stimuli. The nervous system provides rapid, short-lived responses, while the endocrine system provides slower, long-lasting responses. Neurons are the basic units of the nervous system, transmitting electrochemical impulses. A synapse is the gap between two neurons where nerve impulse transmission occurs. The human nervous system comprises the Central Nervous System (brain and spinal cord) and the Peripheral Nervous System. Reflex actions are involuntary, rapid responses mediated by a reflex arc. Hormones are chemical messengers secreted by endocrine glands into the bloodstream. Major endocrine glands include pituitary, thyroid, adrenal, pancreas, testes, and ovaries. Feedback mechanisms regulate the secretion of hormones to maintain homeostasis. Plants coordinate through plant hormones (phytohormones) like auxins and gibberellins. Tropisms are directional growth movements in plants in response to stimuli (e.g., phototropism, geotropism). Adrenaline prepares the body for 'fight or flight' responses during stress. Common confusions It is easy to think Plants do not have control and coordination because they lack a nervous system. The clearer idea Plants exhibit sophisticated control and coordination through chemical signals (plant hormones) that regulate their growth, development, and responses to environmental stimuli like light, gravity, and touch. It is easy to think All body responses are voluntary and require conscious thought. The clearer idea Many body responses, particularly reflex actions (e.g., blinking, withdrawing hand from heat), are involuntary and occur automatically without conscious thought to protect the body rapidly. It is easy to think Nerves and hormones work completely independently in the body. The clearer idea While they operate through different mechanisms and speeds, the nervous and endocrine systems often interact and influence each other to achieve integrated control and coordination of body functions, ensuring a holistic response.
