What else can I help you with?
The pineapple plant closes its stomata during the day and opens its stomata during the night. This process helps the plant conserve water by preventing?
transpiration.
. 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?
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.
Is water loss in plants greater during the day or at night?
Water loss in plants is typically greater during the day due to the process of transpiration, where water is lost through the stomata on the leaves. This is because transpiration rates are usually higher when the stomata are open for photosynthesis to occur. At night, when photosynthesis does not take place, transpiration rates are lower.
When the stomata in a leaf close during the day then?
When the stomata in a leaf close during the day, it helps to reduce water loss through transpiration and conserves water within the plant. However, it can also limit the entry of carbon dioxide for photosynthesis, potentially slowing down the plant's growth and metabolism.
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.
What is the advantages of a stomata being closed at night?
Closing stomata at night helps conserve water by reducing transpiration when there is no sunlight for photosynthesis. It also prevents the loss of stored sugars and other nutrients through transpiration during the night. Additionally, closing stomata at night can reduce the risk of herbivory or pathogen entry when the plant is less active.
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.
Why transpiration does not takes place at night?
Transpiration does not occur at night because the stomata (small openings on leaves that allow for gas exchange) typically close in the absence of sunlight. The closure of stomata helps to conserve water and prevent excessive water loss from the plant when there is no light available for photosynthesis.
How many stomata are likely to open 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 do some plants open their stomata by night instead by day?
Very few of them do open 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.
