Q:

Why are stomata on the bottom of leaves?

Quick Answer

Stomata are found on the bottom of leaves to reduce dehydration. Water is lost through these small pores, which usually can only be seen with a microscope.

Full Answer

Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.

  • Q:

    What is the function of stomata?

    A:

    Stomata are microscopic openings on the surfaces of plant leaves that allow for the easy passage of water vapor, carbon dioxide and oxygen. They are crucial to the function of leaves as photosynthesis requires plenty of carbon dioxide as well as the release of waste oxygen and excess water. "Stomata" means "mouth" in the Greek language.

  • Q:

    What causes the stomata to open and close?

    A:

    There are guard cells surrounding each stoma that cause them to open or close throughout the life cycle of the plant. This occurs in response to water and ion concentration in the plant cell, according to Pearson Education.
