Cross Section Of A Leaf Stomata
Glass slides and cover slips.
Cross section of a leaf stomata. The epidermis contains stomata. This type of stomata can be found in more than ten dicot families such as caryophyllaceae and acanthaceae. Next to stomata when leaf has lots of water guard cells become turgid so the gap between them is larger so more carbon dioxide can diffuse through.
A cross section through a leaf features of leaves and their functions the role of stomata the stomata control gas exchange in the leaf. When the leaf has little water the guard cells become flaccid and closes the stomata so it conserves water. Tiny pores small holes surrounded by a pair of sausage shaped guard cells.
Sensitive to light so closes during night. These cells can change shape in order to close the pore. Just inside the cuticle lies the epidermis.

Whereas the transparent thin epidermal skin of the leaf allows the student to observe the stomata and other epidermal cells it would be important to prepare a cross section of a leaf to observe the arrange of cells inside the leaf structure. It is sometimes called caryophyllaceous type.
