Question

Why carbondioxide is essential for photosynthesis?

Answer 1

Carbon dioxide is needed for photosynthesis. The lower part of the leaf has loose-fitting cells, to allowcarbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily. Carbon dioxide is present in the air we breathe, at very low concentrations.

Answer 2

Carbon dioxide provides the carbon that the plant uses to produce glucose. Carbon dioxide is combined with water using the energy from sunlight. The carbon in glucose is not only used in cellular respiration to make ATP, but actually makes up most of the plants. The majority of a plants mass comes from the carbon that it gets from carbon dioxide(not the soil or else potted plants would gradually suck out most of the soil around them) after the sugar it makes is metabolized into other things.

During photosynthesis, the plants take carbon dioxide (which is present throughout the air) and water (which is also in the air and dirt) and turn it into sugar, among other compounds. Plants also produce oxygen during photosynthesis.
