∙ 11y agoYes stomata is found on duckweed just like all other plants floating or not. Without stoamta the plant would not survive and be able to go through photosynthesis!
Wiki User
∙ 7y agoBecause the plant is designed to float. The stomata allows for gas exchange by the plant... if the stomata were on the underside of the leaf, gas exchange couldn't happen.

Why is stomata not on the top of the leaf?
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.
Where does most transpiration occur in a leaf?
On the bottom of the leaves. This is because Stomata, the place in the leaf were gaseous exchanges of water and carbon dioxide occur, are more common in this part of the leaf compared to the top of the leaf. This is an adaption, because if plants had all of their stomata on the top of their leaves, excessive loss of water will be lost to the environment and cause dehydration of the plant and even potential death.
Why are more stomata present on the lower surface of the leaf?
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.
Why would it be an advantage for a plant to have stomata on the underside of a horizontal leaf?
Having them on the underside reduces water loss. When water evaporates, it rises. Since there is a leaf blocking the moisture from rising, most is just reabsorbed by the plant. There is also less sunlight exposure from the sun on the underside. Stomata have guard cells surrounding the opening that swell and shrivel depending on water availability. If the stomata were on top of the leaf, the guard cells would shrivel too easily from the heat. This closes the stomata so the plant can retain water, but without carbon dioxide entering the plant, it cannot photosynthesize. Also, on the top side of the leaf is the cuticle, a waxy layer that protects the leaf. If stomata were on the top, they would have to be strong enough to do the same job as the cuticle, which they are not. The stomata would be damaged too easily by the environment, putting the whole plant at a disadvantage.
What will happen if there are too many stomata on the top of the leaf?
Stomata are a plants way of exchanging gasses in photosynthesis. The stomata also are resoponsible for transpiration. Most plants have stomata on the under side of the leaf in order to prevent too much water loss. There already is a lot of stomata in leaves but I think you mean to ask "What would happen if the stomata were open all the time?" this would result in mass water loss and cause a plant to wilt.Edited answer:Large number of stomata will increase porocity of the leaves and will facilitate better gaseous exchange and more transpiration.
Do lotus leaf have stomata?
Yes they do! All leaves have stomata, but the lotus's stomata are on the top of the leaf, not the bottom.

How do Lily's breath?
Using their stomata normally located under the leaf, but since the bottom of the lily pad's leaf is submerged in water, the stomata are on the top of the leaf.

What side of the leaf are stomata found?
Most stomatas are found on the bottom of a leaf, a few can be found on the top depending on the plant variety
Why is the stomata at the top for xerophytes?
Xerophytes definitly have their stoma on the BOTTOM of the leaf not the top, this is to minimise water loss through transpiration
Why are more stomata present on the lower surface of the leaf?
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.
