👌

Answer 1

Tropic movements are important for plants because of the following reasons:

• They serve as protective function. They help in developing a sudden response for a stimulus or change.
• It helps in the growth of pollen tubes towards the ovules.
• It helps in the growth and development, by facilitating the movement of plants towards sunlight, nutrients, water, etc.

Two Tropic Movements:

• Phototropism : The movement or growth of a part of the plant in response to light is called phototropism. Stems show positive phototropism and roots show negative phototropism.
• Geotropism : The growth or movement of a part of plant in response to gravity is call geotropism. Here, stems are negatively geotropic and roots are positively geotropic.
