Control and Coordination
Your child will discover how bodies react in milliseconds while plants bend over hours. This chapter usually fetches about five marks, often a reflex-arc or hormone-function question. Learners trace the reflex arc from receptor through the spinal cord to the muscle, study the structure of a neuron, divide brain labour among sensing, thinking and movement regions, follow plant bending toward light and gravity through chemical signals, and survey human glands from thyroid to adrenal regulating growth, sugar and stress response. Three errors appear. Students route reflexes through the brain inste
