Question

Quizplus · Accepted Answer

Photosynthesis involves the process of carbon dioxide and water being converted into glucose (a form of sugar) and oxygen using sunlight as the energy source. This process is carried out by chloroplasts present in the leaves of green plants. So, option B is the correct answer.

Option A is incorrect because it's the opposite of what happens during photosynthesis which uses up carbon dioxide and releases oxygen.

Option C is incorrect because respiration is a separate process of releasing energy from glucose and does not involve photosynthesis.

Option D is incorrect because important reactions occur within the leaves of plants, specifically in the chloroplasts, which are responsible for photosynthesis.
