Select the INCORRECT statement regarding respiration in plants.

Correct option is B

Sol: The correct answer is (b) Carbon dioxide is added to the atmosphere during the day

Key Points:

• During the day, plants perform photosynthesis, where they use carbon dioxide ($$CO_2$$​) from the atmosphere and release oxygen ($$O_2$$​).
• While respiration occurs continuously (day and night), during the day, the net exchange of gases involves uptake of $$CO_2$$​ for photosynthesis and release of $$O_2$$​​
• Plants do not add $$CO_2$$​ to the atmosphere during the day; instead, they reduce $$CO_2$$​ levels.

Information booster:

• Plants exchange gases through stomata, tiny pores on leaves, allowing $$CO_2$$ uptake for photosynthesis during the day and $$O_2$$​ intake for respiration at night, regulated by guard cells through diffusion.
• ​Intercellular spaces in plant tissues allow gases like oxygen and carbon dioxide to diffuse freely, enabling efficient gas exchange for processes like photosynthesis and respiration
• ​Oxygen and $$CO_2$$​ are exchanged by diffusion in plants, moving along their concentration gradient without requiring energy, facilitating gas exchange during photosynthesis and respiration.​
