because its the best time for photosythesis. otherwise water from leaf will be evaporated from transpiration AND plant would not photosynthesis.
soo.. opening on hot day would be a waist

. CAM plants close their during the day and open them at night?
stomata
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called?
CAM plants
Do guard cells open during the day to allow gases to flow through the stomata?
Yes this is true.
Does the stomata on a leaf have to be open or closed during the Calvin benson cycle?
The stomata better be open so that plenty of carbon dioxide diffuses into the leaf and feeds into the Calvin cycle and makes sugars, specifically glyceraldehyde-3-phosphate.
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
What change occurs in the stomates on a hot and humid day?
The stomata remain wide open
Why does the stomata of a desert plant close during the day?
In desert plants, the stomata is open during night. During night, desert plants (also called xerophytes) absorb co2 and form an intermediate. Then during day time when the stomata is closed to prevent loss of water, they use this stored carbon dioxide to perform photosynthesis.
Does a cacti open its stomata during the day?
no!
When are the stomata usually open?
during the day
. CAM plants close their during the day and open them at night?
stomata
CAM plants close their what during the day and open them at night?
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called?
CAM plants
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.
When are the stomata of leaves usually open?
Depending on the environment of the plant, stomata will open and close at different times. In hot, dry environments stomata will open around dusk and dawn to minimise water loss. In Wet environments stomata will open during the day as needed
Do guard cells open during the day to allow gases to flow through the stomata?
Yes this is true.
What regulates the stomata?
The guard cells open and close the stomata as needed.
Does the stomata on a leaf have to be open or closed during the Calvin benson cycle?
The stomata better be open so that plenty of carbon dioxide diffuses into the leaf and feeds into the Calvin cycle and makes sugars, specifically glyceraldehyde-3-phosphate.
