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 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.


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.


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 do some plants close their stomata at night?

At night, there is no light, therefore no photosynthesis (which is the process of making energy from light). Photosynthesis uses CO2, however since photosynthesis is not occurring at night, there is no need to acquire CO2.Some plants (CAM plants) only open their stomata at night, however, in order to take in CO2 and store it until it is light and they can use photosynthesis then. This helps to eliminate water loss through the stomata which would occur more rapidly if the stomata were open during a hot day. (therefore, most CAM plants are found in desserts and such)


Why are a plant's stomata generally open during the day and closed at night?

A plant's stomata are generally open during the day to allow for the exchange of gases like carbon dioxide and oxygen needed for photosynthesis. They are closed at night to prevent water loss through transpiration when photosynthesis is not occurring.

How do plants breathe in oxygen at night?

It is through a opening called 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 happens to the oxygen produced by the Calvin cycle in CAM plants during the day, when their stomata is closed?

It is widely known that CAM plants open their stomata at night time to fix the CO2 in form of organic acids. However, during the light reactions in daytime O2 is evolved while the stomata are closed and there is no way out. The question goes to the possible mechanism by which these plants can handle this high oxygen level during the daytime, while the stomata are closed. Do these plants have an oxygen accumulation and release system like that of CO2? Is such a mechanism studied or described elsewhere?

What do leaves go through at night?

At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.


Where do c4 and cam plants store co2?

C4 plants store CO2 in the mesophyll cells, where initial carbon fixation occurs using PEP carboxylase. CAM plants store CO2 in vacuoles within their cells during the night, when stomata are closed, and use it during the day for photosynthesis when stomata are open.


What plants close stoma to control transpiration?

Plants can close their stomata to reduce water loss during times of stress using mechanisms like the accumulation of ions that cause osmotic changes, as well as the production of abscisic acid which signals stomatal closure. Additionally, certain plants, like succulents and CAM plants, have specialized adaptations that allow them to limit water loss by keeping their stomata closed during the day and opening them at night.


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.
