That depends on whether or not the plant wants it to be open or closed.

What time of day would you exspect the stomata on a plant to be open or closed?
at night when there is little to no light.
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.
How do plants breathe at night when the stomata closed?
As humans plants also need oxygen to breathe they only take in carbon dioxide to do photosynthesis.So they wont do photosynthesis at night and so they only need to breathe. even though their stomata are closed at night some oxygen can go inside. and this is how plants breathe when their stomata are closed. pipidipo
What will happen if there are too many stomata on the top of the leaf?
Stomata are a plants way of exchanging gasses in photosynthesis. The stomata also are resoponsible for transpiration. Most plants have stomata on the under side of the leaf in order to prevent too much water loss. There already is a lot of stomata in leaves but I think you mean to ask "What would happen if the stomata were open all the time?" this would result in mass water loss and cause a plant to wilt.Edited answer:Large number of stomata will increase porocity of the leaves and will facilitate better gaseous exchange and more transpiration.
Why does duckweed have stomata on the top surface of the leaf?
duckweeds does not have stem but only roots.
What part of the day would the stomata be closed?
midday
Why are stomata's in the lower epidermis but not in the upper epidermis?
The explanation lies in how the stomata works. They regulate any gases that pass through them. When the temperature is too hot, it will close to conserve water vapor but this will block CO2 coming in also. Therefore plants don't want to have their stomata closed all the time nor opened all the time. Sunlight hits the top of the leaves and therefore the temperature and light intensity is higher on the top surface of the leaves. If many stomata were to be located on the top, the plant would loose much of its water and when the stomata closes to conserve water, it won't get as much CO2. Therefore for most plants, the stomata stay on the bottom where the temperature is a bit cooler. Also it is protected from the wind since wind can cause evaporation of water.
What would cause a decrease in gas pressure in a closed container?
Lowering the temperature will cause a decrease in gas pressure in a closed container.
Why would closing their stomata during the day be an advantage for the cacti?
During mid day when the intensity of light and day temperature is higher
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 time of day would you exspect the stomata on a plant to be open or closed?
at night when there is little to no light.
What would happen if the stomata were smaller?
If the stomata were smaller then CO2 would diffuse into the cell less rapidly.
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.
Closing the stomata of a leap keeps CO2 from entering what would cause stomata to close?
they close to conserve water
Closing the stomata of a leaf keeps CO2 from entering what would cause the stomata to close?
They close to conserve water.
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.
What would cause a radiator cooling fan not to shut off?
A/C or defroster on Relay stuck in closed position Temperature sensor not sensing proper temperature
