Photosynthesis does not occur in the absence of light during the night.

But there are some plants where reverse mechanisms occur for e.g.

TimesMojo is a social question-and-answer website where you can get all the answers to your questions.

Functions of Stomata: The main function of stomata is to open and close the pores in the leaves for an exchange of gases. This exacerbates the transpiration problem for two reasons: first, RuBisCo has a relatively low affinity for carbon dioxide, and second, it fixes oxygen to RuBP, wasting energy and carbon in a process called photorespiration.

This saturates RuBisCO with carbon dioxide, allowing minimal photorespiration. Debbie Swarthout and C.Michael Hogan. stomata diagram night plant labelled well draw neat grasscity rate cycles climate should care why

They convert it to things that aren't gases -- oxaloacetic acid or malate, or 3-phosphoglycerate, or possibly others that haven't been noticed yet.

I think your answer is quite good, but could use some expansion - what happens during the night with CAM, C4 or C3? Stomata | Opening and Closing of Stomata | Class 10 | Biology | ICSE Board | Home Revise Watch on

Plants have ways to grab onto CO2 so it won't just drift away.

Photosynthetic systems may calculate water use efficiency (A/E), g, intrinsic water use efficiency (A/g), and Ci. However, it has been recently shown that stomata do in fact sense the presence of some, if not all, pathogens. Stomata are very small openings in membranes, particularly in plants, through which water and gas pass. During the day, stomata close if the leaves revel in a lack of water, akin to right through a drought. They take up CO2 during the night through stomata and store it in their photosynthesising cells in the form of an intermediate until the day.

Succulents have a sponge-like interior that stores a lot of water. 8 Why do cacti open their stomata at night?

But as fascinating as these stomata look, their function is even more exciting.

Stomata are mouth-like cellular complexes at the epidermis that regulate gas transfer between plants and Stomata are thus named because they permit the exchange of gases between the atmosphere and the inside of the leaf.

Photosynthesis also produces energy-rich carbohydrates like starch. A group of mostly desert plants called "CAM" plants (Crassulacean acid metabolism, after the family Crassulaceae, which includes the species in which the CAM process was first discovered) open their stomata at night (when water evaporates more slowly from leaves for a given degree of stomatal opening), use PEPcarboxylase to fix carbon dioxide and store the products in large vacuoles. The inverse of r is conductance to water vapor (g), so the equation can be rearranged to[12], Photosynthetic CO2 assimilation (A) can be calculated from, where Ca and Ci are the atmospheric and sub-stomatal partial pressures of CO2 respectively[clarification needed].

Then, because of rings of cellulose microfibrils that prevent the width of the guard cells from swelling, and thus only allow the extra turgor pressure to elongate the guard cells, whose ends are held firmly in place by surrounding epidermal cells, the two guard cells lengthen by bowing apart from one another, creating an open pore through which gas can diffuse.[6]. Stomata open during daytime and close at nighttime because of the presence of light.

They allow the exchange of gases and hence are essential for photosynthesis. Your email address will not be published.

In leaves, they typically open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water. Stomata are tiny holes found in the underside of leaves. This makes the cell plasmolysed, which results in the closing of the stomatal pores. stomata close

Why does the stomata open and close during the day?

It provides plants to maintain their temperature or get cooling effect in day time.

Movement of water out of the guard cells reduces their turgor, causing the guard cells to shrink and closing the stomata. The stomata is a structure in a plant cell that allows water or gases to be let into the plant.

While C3 plants open their stomata during the day and close them at night, CAM plants open their stomata at night and slam them shut every morning. Stomata are open during the day because this is when photosynthesis typically occurs.

Okay, @GrumpyMammoth, I added a link to a prior similar question that I answered. Some CO2 gets this treatment at the roots (where CO2 concentration can sometimes be as high as 8%) and the storage compounds then get sent toward the leaves along with water and minerals.
