Question

In this article in the second paragraph, it is written that the stomata remains closed at night to reduce water loss. We know that the plants respire and take in oxygen at night. Then how do plants take in oxygen i.e. respiration takes place at night?

Again in this article, it is written that the oxygen during respiration is taken through stomata. Which is correct ??

Answer 1

Plants take in oxygen for respiration at night through structures called lenticels.

Step-by-step explanation:

Plants take in oxygen for respiration during the night by using other structures called lenticels.

Lenticels are small, corky openings on the bark of woody stems and roots. They allow for gas exchange, including the intake of oxygen and release of carbon dioxide. While stomata remain closed at night to reduce water loss, lenticels provide an alternative way for plants to obtain oxygen.

Therefore, both statements in the article are correct. Stomata are primarily responsible for gas exchange during the day, while lenticels serve this purpose at night.
