Write the functions of the following
1) Lenticels. 2) hydathodes. 3) stomata. 4) guard cells. 5) waxy cuticle
Answers
Answer:
Guard cells are a bodyguard of the leaf
Answer:
Explanation:
Lenticels- It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. The name lenticel, pronounced with an [s], derives from its lenticular (lens-like) shape.
Hydathodes- Hydathodes are the structures that discharge water from the interior of the leaf to its surface in a process called guttation. ... It is thought that guttation is a necessary process to absorb solutes when transpiration is suppressed
Stomata- The main function of stomata is to open and close the pores in the leaves for an exchange of gases. It allows the plant to take in carbon dioxide and give out oxygen for photosynthesis. ... It helps to expel the excess water out from the leaves in the form of water vapor.
Guard cells- Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing.
Waxy cuticle- A primary function of the leaf's waxy cuticle is to reduce water loss through the leaves, which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall. ... Stomata are pores on the leaf surfaces that open and close to regulate water and gas exchange.
