Coordination and Response in Plants

This topic introduces tropisms—directional growth responses in plants to stimuli like light (phototropism) and gravity (geotropism). Students explore the relevance of these responses to plant survival. Understanding how plants interact with their environment is a basic principle of biology assessed in ECZ exams. It helps Zambian learners appreciate that even stationary organisms like plants sense and respond to their surroundings, a concept that will be expanded with plant hormones in Form 2.
