Xylem is typically located on the upper surface of a leaf to facilitate efficient water transport from the roots to the photosynthetically active tissues. This positioning allows for optimal light exposure and minimizes the distance for water to travel to the mesophyll cells, where photosynthesis occurs. Additionally, being on the upper side helps reduce water loss through evaporation by limiting exposure to air and sunlight compared to the lower surface, where stomata are primarily located.
What else can I help you with?
Are stomata under surface or upper surface of the leaf?
In most cases it is at the underside of the leaf, as it does not want sunlight to dry it up.
What parts of the plant are responsible to allow air and nutrients to enter the leaf cells respectively?
Stomata are responsible for allowing air to enter the leaf cells through tiny openings on the leaf surface. Nutrients are absorbed by the root hairs from the soil and transported through the xylem and phloem tissues to reach the leaf cells.
What does xylem do to a vein leaf?
Xylem is a type of vascular tissue in plants. There are both xylem and phloem that operate to move material thru the plant.the Xylem are like tubes that carry water and minerals up from the roots of the plant.the Phloem on the other hand are tubes that distribute sugars, amino acids and other organic stuffs.but specifically in the LEAF (from wiki:)"Transpirational pull: the most important cause of xylem sap flow is the evaporation of water from the surfaces of mesophyll cells to the atmosphere. This transpiration causes millions of minute menisci to form in the mesophyll cell wall. The resulting surface tension causes a negative pressure or tension in the xylem that pulls the water from the roots and soil."...meaning basically: when the water evaporates off the leaf (mesophyll layer) it causes a lower pressure in the xylem and so that pressure actually "pulls" the water from the roots to the surface. so basically it shows one way in which the xylem tube functions: by transpirational (=>evaporative) pull.
What makes up the majority of the tissue on a leaf?
xylem
What is the part of the leaf containing the xylem and Phoenix?
Cortex
Where is the xylem and phloem located in a leaf structures?
Xylem and phloem are located in the vascular bundles of a leaf, which are found in the midrib or veins. Xylem is typically located on the upper side of the leaf, while phloem is found on the lower side. These vascular bundles transport water and nutrients throughout the leaf.
Why is the upper surface of the leaf transparant?
siciid
Why is the upper surface of a leaf transparent?
The upper surface of a leaf is transparent because it lacks chloroplasts which carry out photosynthesis. This allows light to pass through the upper surface and reach the chloroplast-rich cells in the lower side of the leaf where photosynthesis occurs.
Where is the stomata in the lotus?
They are found on the upper surface of the leaf.
Are stomata under surface or upper surface of the leaf?

Where is the location of the stomata?
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.
Number of stomata in upper and lower surface of leaf of hibiscus?
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
How water travels through a leaf?
Water enters a leaf primarily through the roots via the xylem vessels, then moves up the stem to the leaf through a process called transpiration. Once in the leaf, water evaporates from the stomata on the leaf surface, creating a negative pressure that pulls up more water from the roots through the xylem. This continuous flow of water through the leaf helps transport nutrients and maintain cell turgidity.
Difference between the upper and lower surfaces of the leaf?
Upper part darker, can see venation more clearly. Upper part (ventral) originates from xylem. Lower part (dorsal) originates from phloem. Do not confuse with other denominations of dorsal/ventral.
Stomata are found on upper or lower surface in lotus leaf?
Stomata in lotus plant is on the upper side of the leaves . BY:Alvir Tuazon
