Question

During respiration in plants, the glucose is breakdown into
A. Carbon dioxide
B. Water
C. Energy
D. All the above

Answer 1

Hint:- Respiration is defined as the process in which plants utilized the sugars generated during photosynthesis along with the oxygen to produce energy for the growth of plants. In simple words, respiration is the contrary of photosynthesis. In plants, respiration happens 24 hours, but at night time respiration is more apparent because the process of photosynthesis terminates.

Complete Answer:-
A process by which plant cells get chemical energy and release carbon dioxide, by the breakdown of glucose after the uptake of oxygen from the environment is known as respiration. To proceed with the process of respiration, plant cells need oxygen and a means of eliminating carbon dioxide just as animal cells do. Each portion of the plant such as leaves, stem, and roots performs respiration the same as humans do because plants do not have any specialized organs like creatures for the exchange of gases. In plants, tiny pores present on the surface of leaves that help in the exchange of gases during the process of respiration is known as stomata. Root hairs take the oxygen from the air that is present in between the soil particles and utilize respiration.
Thus, the right option is D.

Note:- Respiration occurs inside the mitochondria (known as the powerhouse of the cell) in the presence of oxygen is known as Aerobic respiration. There are 2 kinds of respiration in plants: Dark respiration ( occurs in the presence or absence of light) and photorespiration ( occurs in the presence of light).
