Question

Herbaceous plants growing in well-watered soils are found to wilt on a hot day. Why?

Answer 1

Reason for the wilting of well-watered herbaceous plants:

1. Herbaceous plants are vascular plants that have no persistent woody stems above ground, and they wilt even in well-watered soil on a hot day because their rate of transpiration exceeds the rate of water absorption by the roots.
2. Herbaceous plants become flaccid, and leaves become soft and wilt because of less water in the cells.
