the amount of oxygen released by a plant during a day and amount of oxygen inhaled by a plant during the night

Answer 1

Plants don't inhale oxygen, they "inhale" carbon dioxide and release it to make oxygen.

Answer 2

Plants absorb carbon dioxide and use it along with water and light to manufacture food for themselves. This process is called photosynthesis. A byproduct of this process is oxygen which is then released to the atmosphere by the plant.
How much carbon dioxide the plant uses and how much oxygen in produces in the process will be dependent on many things. The size of the plant, how many leaves does it have, how much light is it exposed to, how much water is available to it, is it a healthy plant, is it a warm or cold day, etc., etc.
If this was a homework question your teacher does not have a good grasp of botany. There are too many variables involved to produce an accurate answer.
The answer to the question as written though is that the amount of oxygen released by a plant during the day will be dependent on how much photosynthesis is occuring and this will change from day to day and even minute to minute based on many variables.
The amount of oxygen inhaled by a plant at night is "zero" since plants never inhale oxygen. They produce and release it during the chemical process of photosynthesis.

Answer 3

in the night plants need 30-40 % oxygen and day released 70-80% oxygen

Answer 4

No, that occurs at night. Flowering vegetation open and close their stomata during the sunlight hours in accordance with changing circumstances, which includes mild intensity, humidity, and carbon dioxide concentration. it is not completely specific how those responses paintings. regardless of the shown fact that, the consumer-friendly mechanism is composed of regulation of osmotic rigidity. whilst circumstances are conducive to stomatal commencing (e.g., severe mild intensity and severe humidity), a proton pump drives protons (H+) from the look after cells. this implies that the cells' electric powered skill will become progressively greater detrimental, and so an uptake of potassium ions (ok+) happens. This in turn will improve the osmotic rigidity interior the cellular, drawing in water by way of osmosis. This will improve the cellular's quantity and turgor rigidity. Then, by using fact the wall of the look after cellular dealing with the stomatal pore is far less elastic (greater inflexible) than the wall on the choice side of the cellular, the two look after cells bow different than for one yet another, transforming into an open pore during which gasoline can pass. whilst the roots start to experience a water scarcity interior the soil, abscisic acid (ABA) is released. ABA binds to precise receptors interior the look after cells' plasma membranes, which first will improve the pH of the cytosol of the cells and reason the concentration of loose Ca2+ to extend interior the cytosol by using inflow from outdoors the cellular and launch of Ca2+ from inner shops such by using fact the endoplasmic reticulum and vacuoles. This reasons the chloride (Cl-) and inorganic ions to go out the cells. Secondly, this stops the uptake of from now on ok+ into the cells and subsequentally the lack of ability of ok+. The loss of those solutes reasons a alleviation in osmotic rigidity, consequently making the cellular flaccid and so final the stomatal pores. whilst the stama grow to be flaccid some water is misplaced to our environment. This loss of water is asserted as transpiration and is obligatory interior the water cycle.

Answer 5

plants don't inhale oxygen
