Which is more advantageous to plants-more stomata on the upper epidermis or lower epidermis?
upper epidermis for sure>>>
Are their stomata on the upper leaf epidemis of rhoeo spathacea?
Yes, there are stoma present. Rhoeo leaves have dorsiventral symetry. The dorsal side being pink in color have more stomata and ventral side facing sun is green with less stomata per unit area.
Why there are more stomata in lower epidermis than in upper epidermis?
Because lower epidermis remains away from the light and in the absence of light the water loss through transpiration is minimized.
Why lower epidermis has more guard cells?
because lower epidermis is not covered with dust which falls from above.
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

Why do the lemna form their stomata in the upper epidermis?
because the amount of water is less on the lower epidermis, along with the sunlight, and because if lemna formed their stoma in the lower epidermis, transpiration would be scarce.
Are their stomata on the upper leaf epidemis of rhoeo spathacea?
Yes, there are stoma present. Rhoeo leaves have dorsiventral symetry. The dorsal side being pink in color have more stomata and ventral side facing sun is green with less stomata per unit area.

because lower epidermis is not covered with dust which falls from above.
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.
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.
Is the cloroplast layer at the top or bottum of the leaf?
Chloroplast layer is present below and above of the upper and lower epidermis respectively. But more chlorophyll pigment is present on the upper layers.
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 do lotus and water lily have stomata on the upper surface of the leaf?
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
