Question

Write T for True and F for False. Correct the false statement.

Downward growth of roots towards gravity is called phototropism.

Accepted Answer

The statement is false-F.

The downward growth of roots towards gravity is called geotropism.

The response to stimulus is one of the main characteristics of living organisms. Plants are living organisms, but they cannot move from one place to another like animals. However, Different parts of plants respond to different stimuli by moving or bending their parts towards or away from the stimulus.

The response to the stimulus in plants can be explained under the following phenomenon-

Phototropism-The response to the sunlight is called phototropism. The stem of the plant grows upward towards the light. Whereas, roots grow deep into the soil away from the sunlight. Therefore, the stem is positively phototropic, and the roots are negatively phototropic.

Geotropism-The response to the gravity is called geotropism. The stem of the plant moves upward against gravity. Whereas, the roots move downwards towards gravity. Therefore, the roots are positively geotropic, and the stem is negatively geotropic.

Write T for True and F for False. Correct the false statement.

Downward growth of roots towards gravity is called phototropism.
