Question

The plants grows, flowers, and seeds
The plant grows and thrives.
The plant goes into hibernation
The plant withers and dies.

Answer 1

The scientist will observe that the plant withers and dies. The blocking of stomata prevents the plant from transpiring water through evaporation. Transpiration helps to bring water and nutrients from the roots to the leaves of plants. Therefore, blocking stomata will result in a lack of water and nutrients being delivered to the leaves, causing the plant to wither and eventually die.
