How does phototropism occur in plants?
What is happening in the given picture? Which hormone is responsible for this type of movement?
Observe a plant growing near a window and explain how it responds to light and gravity. Identify the types of tropic movements involved and describe the role these movements play in the plant's survival.
In a school science experiment, students planted bean seeds in two pots. Pot A was placed in a well-lit area near the window, while Pot B was kept in a dark cupboard. Over the next two weeks, the students observed the growth of the plants. The plant in Pot A grew straight and healthy with green leaves, while the plant in Pot B became dull, pale, and weak, with small yellow leaves. The students concluded that light plays a crucial role in the healthy growth of plants.
