How does cacti obtain CO2 needed for photosynthesis?
Cacti obtain CO2 needed for photosynthesis through small pores called stomata on their stems. These stomata open at night when it is cooler to minimize water loss through evaporation. During this time, cacti take in CO2 and store it for use in photosynthesis during the day.
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
How does the process of cactus photosynthesis differ from that of other plants?
Cacti have a unique photosynthesis process compared to other plants because they perform a type of photosynthesis called Crassulacean Acid Metabolism (CAM). This allows cacti to open their stomata at night to reduce water loss and store carbon dioxide, which is then used during the day for photosynthesis. In contrast, most other plants perform photosynthesis during the day through a process called C3 photosynthesis, where stomata are open during the day.
How has the succulent adapted its stomata to prevent too much water loss?
it does does . god works . don't ever question gods works .
. CAM plants close their during the day and open them at night?
stomata
Which plants keep their stomata open only at night?
In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place. As they also allow transpiration (water loss) the stomata of most plants close during the night when photosynthesis is not possible. There is a group of mainly desert plants known as CAM plants. These carry out a process called Crassulacean acid metabolism, which effectively allows them to store carbon dioxide in their leaves. In these plants the stomata are normally closed during the day to prevent water loss when temperatures are high, and open during the night when temperatures are lower.
Why are stomsta shut at night?
Stomata are shut at night to conserve water. When there is no light, plants cannot fix carbon dioxide. Stomata are usually open to allow entrance of carbon dioxide. A side effect is that water is lost from the leaves.There is an exception to this, however. CAM plants such as cacti and succulents open the stomata at night, store carbon dioxide as acids, and close them during the day to prevent dessication from harsh desert conditions.
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.
When are the stomata usually open?
Stomata are typically open during the day to allow for gas exchange, such as photosynthesis (uptake of carbon dioxide and release of oxygen). They usually close at night to conserve water and prevent excess water loss through transpiration.
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?
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 (Crassulacean Acid Metabolism) plants. CAM plants have adapted their carbon fixation process to avoid water loss during the day by keeping stomata closed, and perform photosynthesis during the night when conditions are cooler and less water loss occurs.
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.
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.
