Because the water keeps the plant cool so the sun won't over-heat the stomata like a regular plant on land.
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.
They are found on the upper surface of the leaf.
The underside of leaves is where the 'stomata' are to be found in most (not all) plants and it is through these stomata that the gas exchange occurs. The upper surfaces of leaves are usually tough and shiny to protect the leaf and shed water. If the stomata were on the upper surface and the leaf was wet, the water would block them and impede gas exchange.
Stomata in lotus plant is on the upper side of the leaves . BY:Alvir Tuazon
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
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
In most cases it is at the underside of the leaf, as it does not want sunlight to dry it up.
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
Duckweed has stomata on the top surface of the leaf to minimize water loss and prevent desiccation. By having stomata on the upper surface, duckweed can control gas exchange while reducing exposure to dry and windy conditions.
Pondweed does have stomata, It is located on the upper surface on the leaf as it still needs to photosynthesis and cant get sun from underneath.
The stomata are located on the lower surface of a leaf.
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.
