does plant take CO2 during day I want to know more about their respiration and breathing wanted taken and what did take out it's little doubt for me to understand this topic.

Solution

Photosynthesis:
carbon dioxide + water+ light energy -> oxygen + glucose

Plants respire all the time, day and night. But photosynthesis only occurs during the day when there is sunlight.


Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide as follows.

Dark – Only respiration takes place. Oxygen is consumed while carbon dioxide is released.

Dim sunlight – Photosynthesis rate equals respiration rate. A plant consumes all the oxygen photosynthesis generates. It also uses all the carbon dioxide respiration creates. As a result, no gas exchange takes place with the environment.

Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen. Extra oxygen is released into the atmosphere.

During daytime, photosynthesis produces oxygen and glucose faster than respiration consumes it. Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use.

This is why plants are so important to human and other animals’ survival. Without photosynthesis, we wouldn’t have oxygen or food to stay alive.

What Is The Difference Between Cellular Respiration And Breathing
People breathe. Animals breathe. Do plants breathe?



Breathing refers to the act of inhaling air into the lung and then expelling it out of the bodies afterwards. So it’s a physical process of exchanging gases between the living objects and the environment.



Plants do not breathe in the strictest sense of the word. Plants respire.

During respiration and photosynthesis, gases go in and out of the plants through little holes called stomata using diffusion, not breathing.

But in everyday lives, we use those words slightly differently because we are not all biologists or chemists.

Respiration in plants is strikingly similar to why living objects breathe.

Living objects breathe because they need to obtain oxygen to carry out cellular respiration to stay alive, just like plants need to respire to stay alive. Then byproducts such as carbon dioxide and water are released and removed from the living objects through breathing, just like plants do when they respire.

Because of these parallel processes, people sometimes imprecisely call respiration in plants as “breathing”.

This is why it is not entirely incorrect if you’re not using this as an answer in exams, but rather, just use it as an analogy. Plants don’t breathe in and out using lungs, but it is an analogy nonetheless.
