Questions
Do the plants respire all day and night or only during the night?
Do the plants respire all day and night or only during the night? Give reasons.
Solution
Plants respire all day and night because their cells need a steady source of energy for all the different processes that happen inside them. Plants need energy to grow, for root cells to get into the ground and take in water and minerals, and for many other things. Therefore, plants are always breathing, day and night.
