plants breathing out CO2 during the night?

Question

do plants breath out CO2 during the night?

Answer 1

i don't know why so many people seem to forget that plants preform cellular respiration just like most living creatures. They respire all day & all night because they need energy all day and all night to preform all their functions (like metabolism and growth).

the preform photosynthesis to convert light energy into glucose but to convert glucose into usable energy (ATP) they do respiration. CO2 is a byproduct of respiration.

CAM plants (desart plants) keep their stomata closed during the day and therefore take in atmospheric CO2 at night.

what you may be referring to is fish die-off just before dawn. Since plants do not release O2 at night but are respiring along with all the other animals (respiring aerobes) and giving off CO2, the dissolved oxygen level gets very low just befor dawn and if it gets too low the fish die. this happens most during the warm months because dissolved oxygen is lower in warmer water.

Answer 2

There is a simple equation for the process of photosynthesis.

6H2O (water) + 6CO2 (carbon dioxide) + Energy (sunlight) -->
C6H12O6 (glucose, simple sugar) + 6O2 (oxygen)

This equation says that plants take in water and carbon dioxide which are absorbed by chloroplasts, which contain chlorophyl, which use energy provided by the sun to convert the water and carbon dioxide to a simple sugar and oxygen.

During the night, the measurement of CO2 may seem to go up, but this is because there is no photosynthesis taking place to convert the CO2 into O2. Therefore the plants are not producing CO2, they are just not converting it either so it has the ability to build up.

Answer 3

No, that happens at night. Flowering plants open and close their stomata during the daytime in response to changing conditions, such as light intensity, humidity, and carbon dioxide concentration. It is not entirely certain how these responses work. However, the basic mechanism involves regulation of osmotic pressure. When conditions are conducive to stomatal opening (e.g., high light intensity and high humidity), a proton pump drives protons (H+) from the guard cells. This means that the cells' electrical potential becomes increasingly negative, and so an uptake of potassium ions (K+) occurs. This in turn increases the osmotic pressure inside the cell, drawing in water through osmosis. This increases the cell's volume and turgor pressure. Then, because the wall of the guard cell facing the stomatal pore is less elastic (more rigid) than the wall on the opposite side of the cell, the two guard cells bow apart from one another, creating an open pore through which gas can move. When the roots begin to sense a water shortage in the soil, abscisic acid (ABA) is released. ABA binds to certain receptors in the guard cells' plasma membranes, which first raises the pH of the cytosol of the cells and cause the concentration of free Ca2+ to increase in the cytosol due to influx from outside the cell and release of Ca2+ from internal stores such as the endoplasmic reticulum and vacuoles. This causes the chloride (Cl-) and inorganic ions to exit the cells. Secondly, this stops the uptake of any further K+ into the cells and subsequentally the loss of K+. The loss of these solutes causes a reduction in osmotic pressure, thus making the cell flaccid and so closing the stomatal pores. When the stama become flaccid some water is lost to the environment. This loss of water is called transpiration and is essential in the water cycle.

Answer 4

Yes! While performing photosynthesis the plant does take in CO2 and release excess O2, during the night, or when there is no light, the plant is performing cellular respiration just like animals, taking in O2 to burn its fuel and letting out CO2 and water vapor, just like you do. Over a plant's lifetime it will take in more CO2 than it lets out, and let out more O2 than it takes in.

Answer 5

Plants produce carbon dioxide all the time because their cells need energy all the time. They use cellular respiration and break up glucose in their mitochondria just like animals do.

Photosynthesis does use carbon dioxide and produce oxygen. Respiration does the opposite.

During daylight hours, the plant uses more carbon dioxide than it is making, so carbon dioxide is probably not escaping from the plant. But the plant IS using respiration and making carbon dioxide in the daytime.

When it's dark, the plant does not do photosynthesis, so it isn't using up carbon dioxide. It doesn't "switch over" to respiration, but respiration continues just as it did in the light. So now the plant is making more carbon dioxide than it is using.

Answer 6

at night the plants produce co2

Answer 7

No plants breath in CO2 and breathe out O2 (oxygen).

Answer 8

Do you mean 02?
Plants take in C02 (breathe in), and breathe out 02; during the day and even at night (light independent photosynthesis).

Answer 9

Plants take in CO2 and put out oxygen.
