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 downward growth of F₂‘X’F₂ (roots) is termed F₂gravitropismF₂ (or geotropism), reflecting plant growth in response to gravity.
- The upward growth of F₂‘Y’F₂ (stem) is termed F₂negative gravitropismF₂ (or geotropism), reflecting plant growth against gravity.
