Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy as sugar.

Photosynthesis is the process of preparing food in the presence of sunlight and chlorophyll.
In this process, the plant uses water from the soil, carbon dioxide from the air, and energy from sunlight to prepare glucose.

Carbon dioxide + Water + light energy → Glucose + Oxygen

During the initial phase of photosynthesis, light energy is harvested to produce ATP and NADPH where water is oxidized to provide electrons and protons.
After the formation of ATP and NADPH, carbon dioxide is reduced to carbohydrates (glucose)
The reduction of carbon dioxide to carbohydrates doesn’t directly depend on the presence of sunlight but on the supply of ATP and NADPH that were formed during the initial phase.

Read the given paragraph about photosynthesis and select the incorrect statement regarding it.Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose molecules. It occurs in chloroplasts, organelles containing the pigment chlorophyll. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen. This process is essential for maintaining the oxygen levels in the atmosphere.
