Which has more stomata the upper or lower epidermis?
Lower epidermis of leaves being away from direct sunlight have more stomata per unit area to minimize exessive traspiration.
Are stomata found in a leaves epidermis?
The leaf and stem epidermis is covered in stomata, or pores. The stomacomplex regulates gas and water exchange in the leaf.
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.
What are the openings in the epidermis of a plant that allow air and water to pass in and out of the leaf?
Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
Why stomata are present only on lower epidermis in nerium leaf?
as nerium is a xerophyte i.e.as it cannot take in sufficient amount of needed water,the sunken stomata are present in the lower epidermis to reduce loss of water by transpiration.there are also certain hair present in the sunken stoma to protect it.
Which has more stomata the upper or lower epidermis?
Lower epidermis of leaves being away from direct sunlight have more stomata per unit area to minimize exessive traspiration.
What are the openings on the lower epidermis called?
Stomata or stoma(plural)stomach
Are stomata found in a leaves epidermis?
The leaf and stem epidermis is covered in stomata, or pores. The stomacomplex regulates gas and water exchange in the leaf.
How does lower epidermis adapt to do it job in the leaf?
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
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 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.

Why lower epidermis has more guard cells?
because lower epidermis is not covered with dust which falls from above.
What are the internal parts of a leave?
Upper and lower epidermis, stomata and mesophyll consisting of palisade, spongy paenchyma and vascular bundles.
Where on the plant are the stomata found?
Stomata are pores in the leaf's epidermis, or outer surface. They are used to regulate the outflow of water vapour and oxygen from the plant leaves as well as the inflow of carbon dioxide into the leaves. Stomata are normally found on the underside of the leaves (protected from direct sun and exposure to wind).
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.
