Question

why CO2 is formed during respiration in plants?

Answer 1

During aerobic respiration, complete oxidation of carbohydrates takes place. Glucose is broken down by oxygen to release energy, while carbon dioxide and water are the by-products of the reaction. ... However, carbon dioxide is still produced. This is called anaerobic respiration and the process occurs in the cytoplasm

Answer 2

all organisms need energy. energy is gained by breaking down chemical compounds such as glucose. for breaking down glucose, we need oxygen which is gained by respiration(while inhaling). the oxygen breaks glucose into CO2 and water and some other organic compounds releasing energy which we use. the same happens in plants and animals . the co2 released out during the process is given out through respiration (while exhaling)
