There are more stomata on the lower epidermis of leaves to reduce water loss through transpiration. Stomata open to allow gas exchange for photosynthesis, but this also leads to water loss. Having more stomata on the lower surface reduces water loss while still allowing for efficient gas exchange.
Because the top of the leaf is covered by the cuticle of the leaf which prevents water loss and transpiration. If there were stomata in the top of the leaf, more water wold be lost and the plant would wilt. The stomata are located in the bottom of the leaf because There is no cuticle there to stop the proccess of transpiration and so doesn't interfere with the proccess of photosythesis.
The upper side of a leaf is exposed to the sun to a greater extent than the lower side of a leaf. Therefore, water evaporating through the upper side will be more than the lower side of a leaf.
The number of stomata is more abundant in the lower epidermis to help reduce the amount of water lost through transpiration.
Stomata are present in plant leaves for gaseous exchange from the atmosphere. A lot of water is also lost due to transpiration through the stomata. To minimize the water loss the stomata remain on the under side of the leaves.
The lower epidermis remains away from direct sunlight hence stomatal perforation on this side minimizes the loss of water by transpiration.
This helps prevent transpiration (water evaporating out of the plant).
Because lower epidermis remains away from the light and in the absence of light the water loss through transpiration is minimized.

Which is more advantageous to plants-more stomata on the upper epidermis or lower epidermis?
upper epidermis for sure>>>
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.
Are their stomata on the upper leaf epidemis of rhoeo spathacea?
No, the upper leaf epidermis of Rhoeo spathacea does not have stomata. Stomata are typically found on the lower leaf surface of most plant species to allow for gas exchange and minimize water loss through transpiration.
Why lower epidermis has more guard cells?
The lower epidermis of a leaf typically has more guard cells because it is exposed to the external environment and plays a crucial role in regulating gas exchange and water loss through stomata. Having more guard cells allows for a higher density of stomata, which helps optimize the balance between gas exchange for photosynthesis and water conservation.
Number of stomata in upper and lower surface of leaf of hibiscus?
The upper surface of a hibiscus leaf generally has fewer stomata than the lower surface. The lower surface tends to have a higher density of stomata to facilitate efficient gas exchange through transpiration. The specific number of stomata can vary depending on the age and health of the leaf, as well as environmental conditions.

Why do the lemna form their stomata in the upper epidermis?
Lemna, also known as duckweed, form their stomata in the upper epidermis to increase gas exchange efficiency. Placing stomata on the upper surface allows for easier access to carbon dioxide from the air for photosynthesis while minimizing water loss through transpiration. This adaptation helps lemna thrive in their aquatic environment.
Is there a difference in the number of stomata on the upper and lower surfaces of a leaf?
Yes, there are more on the lower side than the upper. Stomata on the upper side allow water to easily escape or transpire with direct contact by the sun.
Why lower epidermis has more guard cells?
The lower epidermis of a leaf typically has more guard cells because it is exposed to the external environment and plays a crucial role in regulating gas exchange and water loss through stomata. Having more guard cells allows for a higher density of stomata, which helps optimize the balance between gas exchange for photosynthesis and water conservation.
Like your skin a leafs what protects its more tender inner cells?
tissues are layers of similar cells. the outside layer of a leaf is called the epidermis tissue. the epidermis is made of flat cells . this layer is like the top layer of your skin. it protects the plant.
Why dicot leaf is known as dorsiventral leaf?
Dicot leaf is also called dorsiventral leaf as it has both dorsal and ventral side with identifiable features. The protective layer is named as Epidermis and there is both upper and lower epidermis. In dorsiventral leafs the lower epidermis which is also called abaxial side will have more number of stomata compared to the adaxial side or upper epidermis. The gap between the two epidermis is termed as mesophyll and in dicot leaf we can see a differentiated mesophyll region. The region is differentiated into palisade and spongy tissue. The region just below upper epidermis have elongated parenchyma cells with chlorophyll filled in and they are called Palisade tissues. This is the main reason behind dark green colour at upper side of a dicot leaf.
Number of stomata in upper and lower surface of leaf of hibiscus?
The upper surface of a hibiscus leaf generally has fewer stomata than the lower surface. The lower surface tends to have a higher density of stomata to facilitate efficient gas exchange through transpiration. The specific number of stomata can vary depending on the age and health of the leaf, as well as environmental conditions.
What are the difference between the upper and lower epidermal layer of the santan leaf ixora coccinea?
The upper epidermal layer of the Ixora coccinea leaf is typically thicker and contains more stomata compared to the lower epidermal layer. The upper epidermis also tends to have more cuticle wax to prevent water loss through transpiration. Overall, both layers serve to protect the leaf and regulate gas exchange.
Difference between dicots and monocots in terms of stomata number and distribution?
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
Why it is that the palisadi layer is located only in upper epidermis and not in lower epidermis?
The palisade layer is located in the upper epidermis of a leaf because this is where it can receive the most sunlight for photosynthesis. The arrangement of the palisade layer in the upper epidermis allows for efficient absorption of light energy. The lower epidermis may lack a palisade layer because it receives less direct sunlight and is more involved in gas exchange and water regulation.
