State the function of the structures called stomata that are present in leaf epidermis?

The leaf surface has many tiny apertures called stomata. During respiration oxygen from the atmosphere diffuses into the stomata and then into the cells of the leaf. When carbon dioxide concentration in the cells increases, the stomata opens and releases carbon dioxide into the atmosphere.

Why stomata are present only on lower epidermis in nerium leaf?
as nerium is a xerophyte i.e.as it cannot take in sufficient amount of needed water,the sunken stomata are present in the lower epidermis to reduce loss of water by transpiration.there are also certain hair present in the sunken stoma to protect it.
Are their stomata on the upper leaf epidemis of rhoeo spathacea?
Yes, there are stoma present. Rhoeo leaves have dorsiventral symetry. The dorsal side being pink in color have more stomata and ventral side facing sun is green with less stomata per unit area.
What are Tiny pores found on the ruptured epidermis of woody stems?
Stomata
Which is more advantageous to plants-more stomata on the upper epidermis or lower epidermis?
upper epidermis for sure>>>
Are stomata found in a leaves epidermis?
The leaf and stem epidermis is covered in stomata, or pores. The stomacomplex regulates gas and water exchange in the leaf.
Gaseous exchange occurs in plants through these structures in the epidermis?
stomata
Why are stomata absent or present in low numbers in the upper epidermis?
To minimize the rate of transpiration

What are stomata and what are they?
exchange of gases takes place by simple diffusion directly into each cell through the openings present in epidermis called stomata. Stomata are found on the underside of leaves. :)
Gaseous exchange occurs in plants through these strutures in the epidermis?
The structure in the epidermis that gaseous exchange occurs in plants is through the stomata. A stomata is a tiny opening or pore in the epidermis.
Which part of a plant has stomata?
It is a pore,large numbers of which are present in the epidermis of leaves (especially on the undersurface) and young shoots

What are the pores in the epidermis called?
It is called the stomata.
Epidermis is modified in a root by the addition of?
Stomata
How do you draw and label each part of leaf?
Can't draw a diagram for you but, from top to bottom: cuticle-waxy substance secreted by epidermis cells that waterproofs the leaf upper epidermis-closely fitted together like a jigsaw. no chlorophyll palisade layer-where most photosynthesis occurs. chlorophyll present spongy layer-gases diffuse through this layer. chlorophyll present lower epidermis (contains stomata)-like upper epidermis. stomata contain chlorophyll
