If the temperature is not very hot when would stomata generally be open or closed?
That depends on whether or not the plant wants it to be open or closed.
Why does duckweed have stomata on the top surface of the leaf?
duckweeds does not have stem but only roots.
Which physiological adaptation would decrease the process of transportation in a plant?
You can try putting a layer of oil on the leaf surfaces
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.
Why would it be an advantage for a plant to have stomata on the underside of a horizontal leaf?
Having them on the underside reduces water loss. When water evaporates, it rises. Since there is a leaf blocking the moisture from rising, most is just reabsorbed by the plant. There is also less sunlight exposure from the sun on the underside. Stomata have guard cells surrounding the opening that swell and shrivel depending on water availability. If the stomata were on top of the leaf, the guard cells would shrivel too easily from the heat. This closes the stomata so the plant can retain water, but without carbon dioxide entering the plant, it cannot photosynthesize. Also, on the top side of the leaf is the cuticle, a waxy layer that protects the leaf. If stomata were on the top, they would have to be strong enough to do the same job as the cuticle, which they are not. The stomata would be damaged too easily by the environment, putting the whole plant at a disadvantage.

What part of the day would the stomata be closed?
midday
What do you think would happen if a plant had no stomata?
If a plant did not have stomata on the bottom of its leaves, water and oxygen leaving the plant would not be regulated.
Why would the stomata be in particular be effected if a plant is not watered?
as the stomata is responsible in gas exchange, and it constantly looses water through it the stomata would die out
What structure would control the exchange of these gases in a plant?
stomata
Why does duckweed have stomata on the top surface of the leaf?
duckweeds does not have stem but only roots.
What structure would control the exchange in theses gases in a plant?
The following is a characteristic of monocots are stomata.
When would plant cells need to close or partially close their stomata?
At night or when there is no sunlight available.
What would happen if a plant lacks stomata?
Water could not pass through it and it could not function.
Which physiological adaptation would decrease the process of transportation in a plant?
You can try putting a layer of oil on the leaf surfaces
What would happen to plant if its stomata stayed open all the time?
It would dehydrate because it would transpire too much.
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
