The pores, technically known as stoma, are used to admit air (plants need carbon dioxide from the air in order to perform photosynthesis) and to release water vapor.
The stomata are located on the lower surface of a leaf.
There are about 92 stomatas on upper surface and 39 stomatas on the lower surface. In a dorsiventral leaf number of stomata is more on the lower surface hence the above answer may please be verified
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.
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.
The lower surface of the leaf has the stomata. You can see the reason for this if you cut a leaf in half from upper side to lower side. The upper portion of the leaf consists of tightly packed cells that are full of chloroplasts for taking in light. The lower half of the leaf is made up of loosely arranged cells. This allows room for air to enter the lower part of the leaf through the stomata and contribute carbon dioxide and take away oxygen. The upper surface of the leaf is covered by the cuticle which prevents dehydration, as such the stomata cannot be located or function on the upper surface
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.

Stomata in lotus plant is on the upper side of the leaves . BY:Alvir Tuazon
On a dorsi-ventral leaf most of the stomata are found on the lower side of the leaf, that remains away from sunlight. On an iso-bilateral leaf stomata are present on both the sides, upper as well as lower.
Yes, lotus leaves have stomata, but they are located on the upper surface of the leaf rather than the lower surface. This unique positioning helps reduce water loss through transpiration while still allowing for gas exchange.
The stomata are the pores and the guard cells control the opening and closing of these pores.
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
Small pores on the leaf surface are called stomata. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
