Answer 2

Answer:-

• Option A:- Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar

• Option B:- During true photosynthesis, the carbon dioxide is reduced and water is oxidized. The carbon dioxide is reduced to glucose and the water is oxidized to release oxygen in the presence of sunlight to synthesize nutrients such as carbohydrates in the form of glucose and release oxygen.

• Option D:-To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

• Option D:- To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

• Option C:-Photosynthesis is an example of an anabolic reaction. It synthesizes sugars from the addition of the smaller molecules like carbon dioxide and water in the presence of sunlight, which gives oxygen and glucose in return along with some energy.

• Option D:- Photosynthesis occurs inside the chloroplast of mesophyll cells. In photosynthesis, l ight reactions occur in the membranes of thylakoids. Whereas dark reaction occurs in the stroma of chloroplasts.

• Option D:- Photosynthesis occurs inside the chloroplast of mesophyll cells. In photosynthesis, l ight reactions occur in the membranes of thylakoids. Whereas dark reaction occurs in the stroma of chloroplasts.

• Option C:- Photolysis of water observes release of oxygen, as a by-product, and release of hydrogen. During photosynthesis when chlorophyll is left by its electrons, the place where the electrons were is left with a hole, which is filled by oxidised water. When this oxidised water splits, it releases oxygen and hydrogen.

• Option A:- Light is upmost importance for photosynthesis to occur

• Option B :- Chlorophyll is the informal factor of photosynthesis
