Question

Name the movement which causes ‘X’ and ‘Y’ to grow downwards and upwards respectively. (Refer above figure)

Hint:

Gravitropism is a crucial response for plants to orient their roots downward into the soil for water and nutrients, while the stem grows upward toward light for photosynthesis.

Answer 1

- The movement which causes F₂‘X’F₂ (roots) to grow downwards is called F₂gravitropismF₂ (also known as geotropism), where the plant grows in response to gravity.
- The movement which causes F₂‘Y’F₂ (stem) to grow upwards is called F₂negative gravitropismF₂ (also known as geotropism), where the plant grows against gravity.
