What is the bottom of a leaf called?
The bottom of a leaf is called the abaxial surface. It is typically lighter in color than the top of the leaf and may have different characteristics, such as more stomata for gas exchange.
Why is stomata not on the top of the leaf?
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
Where does most transpiration occur in a leaf?
On the bottom of the leaves. This is because Stomata, the place in the leaf were gaseous exchanges of water and carbon dioxide occur, are more common in this part of the leaf compared to the top of the leaf. This is an adaption, because if plants had all of their stomata on the top of their leaves, excessive loss of water will be lost to the environment and cause dehydration of the plant and even potential death.
What are the key features of simple leaf anatomy?
The key features of simple leaf anatomy include a single blade, a main vein called the midrib, smaller veins branching out from the midrib, and a petiole that connects the leaf to the stem. The leaf is typically flat and thin, with a top surface called the adaxial surface and a bottom surface called the abaxial surface. The outer layer of the leaf is called the epidermis, which contains stomata for gas exchange and a waxy cuticle to prevent water loss.
Why are more stomata present on the lower surface of the leaf?
The pores, technically known as stoma, are used to admit air (plants need carbon dioxide from the air in order to perform photosynthesis) and to release water vapor.
Do lotus leaf have stomata?
Yes, lotus leaves have stomata, but they are located on the upper surface of the leaf rather than the lower surface. This unique positioning helps reduce water loss through transpiration while still allowing for gas exchange.
How do Lily's breath?
Using their stomata normally located under the leaf, but since the bottom of the lily pad's leaf is submerged in water, the stomata are on the top of the leaf.
What is the bottom of a leaf called?
The bottom of a leaf is called the abaxial surface. It is typically lighter in color than the top of the leaf and may have different characteristics, such as more stomata for gas exchange.
Why is the stomata at the top for xerophytes?
Stomata are located on the top surface of xerophyte leaves to minimize water loss by reducing exposure to direct sunlight and wind. Placing stomata on the top surface helps create a more humid microenvironment around the stomata, reducing water loss through transpiration. This adaptation is crucial for xerophytes living in dry environments with limited water availability.
How does the lily and the lily breathe?
Using their stomata normally located under the leaf, but since the bottom of the lily pad's leaf is submerged in water, the stomata are on the top of the leaf.
Are the stoma found more on the top or bottom of a leaf?
Stomata are typically found on the bottom surface of leaves, although some plants may have stomata on both the top and bottom surfaces. This placement helps reduce water loss through transpiration, as the underside of the leaf is usually more protected from direct sunlight and wind.
Why is stomata not on the top of the leaf?
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.

What side of the leaf are stomata found?
Most stomatas are found on the bottom of a leaf, a few can be found on the top depending on the plant variety
