Question

Explain difference between stomata and lower epidermal

Answer 1

Lower epidermisrefers to a single layer of cells on the lower surface of the leaf, which contains. stomata and guard cells.The lower epidermis (abaxial epidermis) covers the lower surface of the leaf.

• It contains stomata cells that help prevent water loss and regulate the exchange of gases such as oxygen and carbon dioxide, enabling plants to survive.

• Other cells in the lower epidermis include a waxy cuticle to protect underlying layers.

• Transparency in epidermal cells allows sunlight to pass through to chloroplasts, which are involved in photosynthesis.

stomata are microscopic pores found on the epidermis of plants. Though most stomata are found on leaves, they can be found on all aboveground parts of a plant. These pores allow the exchange of gases between the outside environment and the air canals within a plant. These pores play a critical role in the process of photosynthesis, and can open and close as a response to environmental conditions.
