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.
What substance is released from the stomata?
Stomata are small openings in a leaf to allow carbon dioxide to get in during the day and oxygen to get in at night. Both gases also pass out through stomata. Water vapor also passes out of stomata.
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.
What guard cells guard?
They are the pair of cells that surround the stomata (pores on the underside of leaves) They can change shape to open or close the stomata. Most plants open their stomata during the day (to allow co2 to enter for photosysthis) and close them at night. However cacti open their stomata during the night to reduce water loss, and have to use stored co2 for photosysthesis.
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.
How stomata occur during night?
Stomata do not occur - during the night or day. Stomata are physical features of leaves: they are there from when the leaf is created to when it dies.
What do cam plants close?
Their stomata during the day!.
. CAM plants close their during the day and open them at night?
stomata
How does CO2 get into a leaf?
Through the stomata, openings in the leaf surface. By diffusion. There are three photosynthesis processes, C3, C4, and CAM. (These names describe part of the chemistry.) The desert plants (and some epiphytes) use CAM, for in this process, the stomata are closed during the day, and open at night. The plant absorbs CO2 into its system as a complex chemical (the CAM bit) over night, and during the day, the stomata close and the plant converts the CAM chemical into CO2 to be used for photosynthesis in the usual way. Normal plants open their stomata during the day, and CO2 diffuses in and O2 out.

What plants close stoma to control transpiration?
All plants use guard cells to control how long stomata should be opened or closed. CAM plants, for example, close their stomata during the day to prevent loss of water.
Why is the function of the stomata?
The stomata are openings in plant leaves through which gasses pass in and out. During the day carbon dioxide passes from the air through the stomata to the leaves and oxygen, produced by the leaf, passes back out through them. At night plants yield up small amounts of carbon dioxide through the stomata.

Does a cacti open its stomata during the day?
no!
