6. Transpiration is a process in which plants (a) receive water from soil. (b) absorb water vapour from air. (c) prepare food from water. (d) release water vapour.
Answer (1)
Transpiration is a process in which plants release water vapor.
Transpiration primarily involves the movement of water from the roots, through the plant, and out into the atmosphere. Here's how it works step-by-step:
Water Absorption : Plants absorb water from the soil through their roots. This water then moves upward through the plant.
Water Movement : The water travels through the plant via the xylem, which is the tissue responsible for transporting water and nutrients.
Water Evaporation : Once the water reaches the leaves, it evaporates from small openings called stomata into the atmosphere as water vapor. This process is known as transpiration.
Importance of Transpiration : Transpiration helps in several ways. It allows plants to cool off on hot days, helps them transport nutrients throughout the plant, and also maintains the flow of water and minerals from the soil.
Based on the choices provided in the question, the correct option is:
(d) release water vapour.
