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.

Why does duckweed have stomata on the top surface of the leaf?
duckweeds does not have stem but only roots.
Where can stomata be found?
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. :)
Stomata are part of which type of plant structure?
Tinyopenings on underside ofleaves
Why are there few stomata on the upper surface of most leaves?
small pores have on the leaves excess water transfer into the atomospehere incase there have have no the stomata (pores) on the leaf the plant will die.must the plant can must drain the water.So the stomata exist upper surface of the water.
Why is water loss in leaves of a plant unavoidable?
Because the Stomata on the underside of the leaf have to open (so stomata are turgid) to allow for the exchange of CO2 and O2 so photosynthesis can occur. As this process takes place water diffuses out of the stomata.
Where is the stomata on the plant?
In the underside of the leaf
What is the small opening in the underside of the plant?
Stoma or stomata
What is the breathing organ of plant?
The Stomata is the small opening on the underside of the left that allows for the absorption of CO2. A plant can open and close the stomata to help cut down on moisture loss.
Are small opening on the underside of leaving through which carbon dioxide enter a plant?
Stomata
What is breathing organ of plant?
The Stomata is the small opening on the underside of the left that allows for the absorption of CO2. A plant can open and close the stomata to help cut down on moisture loss.
If white glue is used to seal the stomata on the underside of plant leaves what will happen to the leaves?
the stomata will be closed off, not allowing gas exchange to occur.
What is the job for the tiny openings on the underside of What is the name for the tiny openings on the underside of the leaves?
they are called stomata and they are used to exchang gases for the plant. It has to be very wet.
Where are stomata generally most abundant in the majority of leaves?
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.
What plant leaf is adapted to prevent water loss?
Most of their stomata are on the underside of the leaf.
How do plants breathe?
They breathe through the stomata and other pigments.Plants have these tiny holes on the underside of the leaves that allows them to absorb co2 and produce O
Where does all of the molecules enter and leave during Plant respiration?
There are pores on the underside of the leaf called stomata they allow transpiration.
What are small openings on the underside of the leaves through which carbon dioxide enters a plant?
Stoma (or plural form stomata for a number of stoma)
