It is located on both sides of leaves but more is present on the bottom side of leaves. However in water plants, it is present on top.

Stomata are typically located on the underside of leaves. This positioning helps to reduce water loss by minimizing exposure to direct sunlight and reducing the chances of evaporation. The presence of stomata on the underside of leaves also reduces the risks of damage from external factors such as wind and heat.

Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
How is the lost water in stomata replaced?
The guard cells of the stomata have greater osmotic pressure due to loss of water. Thus, by way of osmosis this loss is compansated continuously from the surrounding cells of the stomata.
Why are cactus leaves tiny?
I think because in a desert, the cactus doesn't find much water. So, to save water it does not expel much water out of itself, and as stomata is responsible for expelling water of the plant, the cactus has less stomata
What two structures in plants leaves help prevent the loss of water?
The two structures in plant leaves that prevent the loss of water are stomata (located in the bottom part of the leaf) and the epidermis (covers the top and bottom of the leaf).
What plant leaf is adapted to prevent water loss?
Most of their stomata are on the underside of the leaf.
Botanists believe that gymnosperm leaves have evolved sunken stomata below the leaf surface to reduce water loss from?
Transpiration.
How does the stomata density affect the water loss?
When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.

What are the openings in the epidermis of a plant that allow air and water to pass in and out of the leaf?
Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
Where does water plants have stomata?
to prevent excessive water loss by transpiration
What is the importance of guard cells?
If by guard cells you mean the ones located in plants, they open and close the stomata to control water loss :)
Why are cactus leaves tiny?
I think because in a desert, the cactus doesn't find much water. So, to save water it does not expel much water out of itself, and as stomata is responsible for expelling water of the plant, the cactus has less stomata
What can open and close to change the amount of water loss?
stomata
To control water loss the size of the stomata is reduced by the?
Guard Cells

Bot
Which do guard cells control?
