Well, stomata are the pores through which leaves breathe. These are also the pores through which transpiration takes place (Transpiration is the loss of excess water- just like in us, only we call it sweating). So if these pores were on the top of the leaf where sunlight falls directly, then there would be a lot of loss of water through evaporation and it is definitely not good to lose so much water.
So in order to reduce the chance of losing lot of water, these stomatal pores are in the lower leaf.
Leaves in sunny environments may have more stomata to facilitate increased gas exchange for photosynthesis and transpiration. Leaves in shady environments may have fewer stomata to minimize water loss while still allowing for some gas exchange. Additionally, certain plant species may have evolved to have more stomata based on their specific needs for gas exchange and water regulation.
To soak up sunlight and carbon dioxide to enable them to undergo photosynthesis, and to give off oxygen as a waste product.
Some leaves would need more stomata than others if they are in an environment with more water. Stomata regulate the amount of water that goes in and out of a plant through the leaves.

Why are there more stomata on the bottoms of leaves?
This is because, to prevent water loss. If the stomata were on the upper side of the leaf, it would be in direct contact with the sun, which would absorb all the water from the leaf, when the stomata is open (which is around 9am and 3pm). This would not be essential for the leaf, as it would not be able to photosynthesise, hence, unable to respire, therefore, would die due to a lack of food and energy.
What will happen if there are too many stomata on the top of the leaf?
If there are too many stomata on the top of the leaf, it can lead to excessive water loss through transpiration and make the leaf more prone to dehydration. This can affect the overall health of the plant and its ability to photosynthesize efficiently.
Where does most transpiration occur in a leaf?
Most transpiration occurs through small pores called stomata located on the underside of a leaf. Stomata open and close to regulate the exchange of gases and the loss of water vapor in a process called transpiration.
How carbon dioxide enter the leaves?
stomata
Which has more stomata the upper or lower epidermis?
Typically, the lower epidermis has more stomata compared to the upper epidermis. This arrangement helps plants regulate gas exchange, such as carbon dioxide intake and oxygen release, more efficiently.
What kind of living thing breathe through their stomata?
Plants Breathe Through Stomata. Stomata is found on the leaves of a plant. To Learn More Check On The Internet
Where on the leaf is the stomata found and how to prove that?
Stomata are found on the underside of plant leaves. To prove this, you can use a microscope to observe and identify the stomata on a leaf's underside. Staining techniques can also be employed to make the stomata more visible for identification.

Why Carbon-dioxide is absorbed more by lower leaf surface?
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.
Why do lotus and water lily have stomata on the upper surface of the leaf?
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.
What would happen what would happen if rita coated the leaves of her money plant with oil?
By coating the leaves of a money plant with will make these more shiny but it will harm the plant as oily coat will not facilitate exchange of air to and fro stomata.
What will happen if there are too many stomata on the top of the leaf?
If there are too many stomata on the top of the leaf, it can lead to excessive water loss through transpiration and make the leaf more prone to dehydration. This can affect the overall health of the plant and its ability to photosynthesize efficiently.
How do gases enter and leave plants?
In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems. In aquatic plants, gas exchange directly though the tissue surface.
Where is the stomata located to reduce water loss?
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.
How do curled leaves loss less water when compared to flattered leaves?
The percentage of humidity around stomata is more in curled leaves than those of flat leaves, hence the diffusion of water vapour is slower in curled leaves.
Why do most plants have many stomata than lenticels?
Stomata are present in leaves where CO2 is required for photosythesis and lenticels are pesent on woody parts of the plant to provide perforation. SINCE THE REQUIREMENT OF CO2 is more in the leafy areas, there are many stomata than the lenticels.
Where does most transpiration occur in a leaf?
Most transpiration occurs through small pores called stomata located on the underside of a leaf. Stomata open and close to regulate the exchange of gases and the loss of water vapor in a process called transpiration.
