Water vapour is lost in plants during transpiration through
Answer Details
Water vapor is lost in plants during transpiration through stomata and lenticels. Stomata are tiny pores on the surface of leaves that allow for the exchange of gases, including water vapor. When the stomata are open, water vapor is released into the air through a process called transpiration. Lenticels are small openings on the stems and roots of plants that also allow for gas exchange.
Transpiration is an important process in plants as it helps to pull water and nutrients up from the roots to the leaves. As water evaporates from the leaves through transpiration, it creates a negative pressure or tension in the xylem, the tissue responsible for transporting water and nutrients from the roots to the rest of the plant. This negative pressure pulls water and nutrients up from the roots to the leaves, a process known as the transpiration-cohesion-tension mechanism.
The other options listed do not play a direct role in the process of transpiration. Xylem is the tissue responsible for transporting water and nutrients, but it is not involved in the release of water vapor during transpiration. Sclerenchyma and parenchyma are types of plant cells that provide structural support and perform various functions, but they are not directly involved in transpiration. Guard cells are specialized cells that control the opening and closing of stomata, but they are not involved in the loss of water vapor during transpiration.
