Water Loss | MCQs

Explanation

The type of transpiration occurring through special openings in plant stems is called lenticular transpiration.

These openings, known as lenticels, are small pores in the bark of woody stems and allow for gas exchange and water vapor loss. 

Explanation

This refers to the loss of water through the cuticle, the waxy layer on the surface of leaves. 

Sources consistently state that approximately 5-7% of total transpiration occurs via the cuticle. 

Explanation

Plasmolysis is the process by which a plant cell loses water and its cytoplasm shrinks, causing the cell membrane to pull away from the cell wall.

This can occur due to osmotic stress, such as when a plant is exposed to high concentrations of salt or sugar.

Explanation

• Transpiration is the process by which water is transported through the plant and evaporates from the aerial parts.
• Such as leaves, stems, and flowers, primarily through small openings called stomata.
