What is the function of the plant upper epidermis?
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.
Why removing the lower epidermis layer of the leaf and not the upper epidermis?
because most number of stomatal pores are present on lower epidermis of leaves.
What layer is more cellular than the other- Dermis or Epidermis?
the upper epidermis is more cutinized,to prevent excess loss of water from the leaf surface
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.
