Why water lily has stomata on the upper side of leaves?

Answer 1

Because they are water plants they get enough water, unlike say the xerophytes which dont(and so their stomata is on the lower surface to minimise the loss of water) and because they get more than enough water they would want to get rid of it more easily so stomata are on the upper surface!

Answer 2

The stomatas are present on the upper side of a hydrophyte because the hydrophyte lives in water and therefore it gets excess water, so to improve the loss of water through transpiration the stomatas are present on the upper side of the leaf of a hydrophyte. Water has to be lost because the plant can sink as water will make it less dense and heavy.

Xerophytes have stomata on the lower side because they do not get excess water but they get less than what they need, hence the stomatas are present on the lower side so that less water is lost. Secondly, they live in desets and there will be more evaporation as desert is very hot.

Answer 3

Water lilies grow in ponds where their leaves generally float directly on the surface of the water or slightly above it. To thrive in this environment, like all plants, they have developed specialized features , such as to grow stomata on top of their leaves.

Answer 4

Water plants have stomata on top (upper epidermis) because the lower epidermis is in contact, if not submerged in water. Stomata opens and closes to regulate gas exchange and transpiration.

Desert plants or plants where moisture may be unavailable or in short supply for at least part of the year have sunken stomata to reduce water loss.

Answer 5

Stomata is located at the upperside of the leave to get and have carbon dioxide or CO2 and it closes if reached approximately enough carbon dioxide. Carbon dioxide and other gasses move upwards so it is impractical to place a CO2 collecting objects such as a stomata under a leaf where probably the gasses are already scattered in the atmosphere. Leaves looks like an umbrella that makes a cover therefore collecting carbon dioxide from below would be useless since it would be still be covered by the leaf itself and the stomata hasn't have high sunction power that it could collect carbon dioxide from below and if it does have the carbon dioxide will still be scattered since it's flow will still go around the leaf and some carbon dioxide is scattering.

Answer 6

Water lilies have stomata on the upper side of their leaves because they are adapted for living in aquatic environments. Having stomata on the upper side helps prevent water loss from the leaf surface by reducing evapotranspiration and allows the plant to efficiently exchange gases with the atmosphere while being submerged in water.

Answer 7

because water plants need also carbon dioxide that wasn't present in the water.

Answer 8

Type your answer here... because on the top side of aleaf sunlight falls directly and water transpires resulting in less availability of water for photosynthesis

Answer 9

The lower surface may be on the water or in the water and the upper surface is always cleared to accept carbon dioxide from the air into the leaves through the stoma.
