Question

Describe one way how plants respond to stimuli.

Answer 1

Hint: Tropic movement refers to a plant's movement in response to a stimulus in the environment; this movement is triggered by root and shoots development. Plants exhibit tropic movements in response to many stimuli such as light, water, touch, and food. Tropic movements in plants are observed as changes in the growth pattern of the plant shoots and roots.

Complete solution:
Some of the ways by which plants respond to stimuli are described below:
Phototropism is the movement of a plant in reaction to light; it causes the plant to grow in the direction of the light. It can be either positive (if facing the light) or negative (if facing away from the light) (if away from the light).
Geotropism is the movement of plants in reaction to gravity, which causes them to move in the same direction as gravity. Roots will grow downwards, exhibiting positive geotropism, whereas shoots will grow upwards, exhibiting negative geotropism.
Chemotropism - The passage of pollen grains to the female gamete in seed plants is aided by the release of chemicals. This demonstrates chemotropism in a good way.
Hydrotropism is the movement of plants in reaction to water; the roots of the plant will grow in the direction of the water.
Thigmotropism is the reflex movement or activity of a plant in reaction to being touched. The touch me not plant is a good example of this. The leaves droop as soon as they are touched.

Note:
Tropic movement is the movement of a plant in response to stimulus. It's significant because: They act as a form of protection. They also aid in the development of quick reactions during a charge. Furthermore, they assist in plant growth and development by allowing the plant to migrate closer to the sun. Thus, tropic movements are an integral part of plant physiology.
