Question

Routinely, in nature, during a 24-hour period in nature, what substance do green plants continuously require and use?​

Answer 1

Routinely, in nature, during a 24-hour period in nature, green plants continuously require and use oxygen and carbon dioxide.

Throughout the day and night, the leaves absorb oxygen from the air through stomata, which are openings in their surface.

The absorption of oxygen allows them to use the carbohydrate reserves to obtain this energy, then expelling carbon dioxide and water vapor at the end of the process.

That is, the stomata allow oxygen, carbon dioxide, gases and water to leave and enter the leaves.

In turn, stomata and lenticels are part of the stomatal apparatus, along with the rest of the epidermis of plant species, it is there where gases such as carbon dioxide and oxygen accumulate.

Therefore, we can conclude that during a 24-hour period in nature, green plants continuously require and use oxygen and carbon dioxide, respiration occurs during the day and at night; to do this, plants take oxygen from the air and release carbon dioxide.

Answer 2

Answer:

Plants take in oxygen all the time for respiration.

Photosynthesis which begins by combining water and CO2, continues in the "dark phase" in making the glucose molecule. Light is not used for this part of the reaction so it is called dark , because light is needed for the first part.
