Because in leaves it is mostly the upper side facing the sun and receiving light for photolysis of water by the chlorophyll present in the chloroplasts of palisade layer cells hence the palisade layer in dorsiventral leaves is present below the upper epidermis of leaves.
This answer refers to the cell layers of a plant leaf: There's the outer cuticle, the upper epidermis, the palisade mesophyll cell, the bundle sheath cell (containing xylem and phloem) surrounded by spongy mesophyll cells and then the lower epidermis. Not sure if this helps...
Chloroplast layer is present below and above of the upper and lower epidermis respectively. But more chlorophyll pigment is present on the upper layers.
Upper epidermis and lower epidermis
upper epidermis for sure>>>
uhhhm. peanut butter?! (this question wanst answered before anyways, so don't be disspaointed.) First of all, this is NO help whatsoever. You don't need to be doing this, these are serious questions, and immature idiots like you don't need to be on here answering questions like this, this makes people so angry!
Answer: the epidermis of a leaf includes: upper epidermis and lower epidermis but if you are referring to the epidermis of an onion: it is only one layer
how many layer of cells make up upper epidermis and lower epidermis
because most number of stomatal pores are present on lower epidermis of leaves.
Epidermis is the top layer of skin and the one you can actually see. The dermis is the layer that lies underneath the epidermis, and it is composed entirely of living cells. The most important function of dermis is respiration. The various glands such as the oil and sweat glands originate in the lower dermis. From here, they rise to the surface of the skin to eliminate waste matter.
mesophyll layer
In a leaf,a most of the chloroplasts are found in the upper epidermis layer. A leaf has four distinct tissue layers, upper epidermis, lower epidermis, spongy layer, and palisade layer.
the function of epidermis: in the lower part there is the sign,cellula,membrua, sinkline, and midrib in the upper part of epidermis there is also the sign cell, cellule, membrua, and sinotopilensicuaye and in wax layer is the botany crispifiedencius "crispifiedencius" is a kind of cell which leaves layer the insects into it. and the last layer is synocimprotocium membulare crisd.

Human skin is composed of three layers. The top layer is the epidermis, the middle layer is the dermis and the lower portion of the skin is the lower dermis.
Below the upper epidermis and above the lower epidermis.
the upper epidermis prevents water loss while the lower allows gases to enter and exit, resulting in photosynthesis
4 tissues: The Upper Epidermis The Palisade layer Spongy Layer The Lower Epidermis. All these tissues do very different jobs! XX
