because as the temperature rises plants transpire more rapidly.
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.
Stomata in lotus are primarily located on the upper surface of the leaves. This adaptation helps to minimize water loss through transpiration by reducing exposure to sunlight and wind, which can promote evaporation. The positioning of stomata on the upper surface also allows for efficient gas exchange and absorption of carbon dioxide.
From what I know about plants, the leaves have stoma in the bottom layer. Stoma are holes, through which excess water moves out of during transpiration The weather, humidity, water potential gradients and temperature all affect transpiration rates.
The transfer of moisture from vegetation to the atmosphere through the stomata of plant leaves is called transpiration. Transpiration helps plants regulate temperature, transport nutrients, and maintain cell turgidity. It also creates a suction force that helps pull water and nutrients from the roots to the upper parts of the plant.
Stomata are mainly found on the undersurface of leaves to reduce water loss through transpiration. The lower surface is generally more shaded and cooler compared to the upper surface, which helps to minimize water loss by reducing the rate of transpiration. Additionally, having stomata on the undersurface can also protect the stomata from direct sunlight, preventing excess water loss.
The pattern of stomata on the leaf surface can vary widely among different plant species, but they are typically more numerous on the lower (abaxial) surface than on the upper (adaxial) surface. Stomata can be arranged in a random pattern, in rows, or in clusters, depending on the plant's adaptation to its environment. This arrangement helps optimize gas exchange while minimizing water loss, particularly in plants adapted to dry conditions. Overall, the specific pattern reflects the plant's strategy for balancing photosynthesis and transpiration.

Transpiration in a leaf causes water to be lost through the stomata, leading to a decrease in internal water pressure. To compensate for this loss, stomata are typically distributed more on the lower surface of a leaf where there is less direct sunlight and wind exposure, helping to reduce excessive water loss and maintain the plant's hydration levels.
Cobalt chloride paper is used to study rate of transpiration through the upper and lower surface of leaf.The upper surface of leaf has less number of stomata so more time will be taken to change from blue to pink by cobalt chloride paper; while the lower surface of leaf has more number of stomata so less time will be taken to change from blue to pink by cobalt chloride paper. This is because the fact that the transpiration rate is higher when stomata are more in number and vice versa.
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
No, the upper epidermis of a leaf is not specialized for photosynthesis. Its main function is to protect the underlying mesophyll tissue and help reduce water loss through the leaf surface. Photosynthesis primarily occurs in the mesophyll cells located below the upper epidermis.
