EXPLANATION
GS20. What is the process by which plants release water vapor through their leaves?
a) Transpiration
b) Photosynthesis
c) Respiration
d) Germination
ANSWER: a) Transpiration
EXPLANATION:
The process by which plants release water vapor through their leaves is:
a) Transpiration
Transpiration is the process by which water vapor is released from the surfaces of plant leaves, stems, and other plant parts into the atmosphere. It occurs through small openings on the leaves called stomata. Transpiration helps plants to regulate temperature, transport nutrients, and maintain cell turgidity. It is a crucial part of the plant's water cycle.
WRONG OPTIONS:
Option b) Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen, typically occurring in the leaves.
Option c) Respiration is the process by which living organisms, including plants, convert glucose and oxygen into energy, typically occurring in the cells.
Option d) Germination is the process by which a seed begins to grow into a new plant.
Therefore, the correct answer is a) Transpiration.
