Carbon dioxide reacts with water in presence of sunlight and chlorophyll to produceglucose, oxygen and water.

This statement is describing the process of photosynthesis, which is how plants produce their own food. Here's the step-by-step process:

1. Carbon dioxide enters the plant through small openings in the leaves, stems, and roots called stomata.

2. Water is absorbed by the roots and transported to the leaves.

3. In the chloroplasts (the part of the plant cell responsible for photosynthesis), sunlight is absorbed by a pigment called chlorophyll.

4. The energy from the sunlight is used to convert the absorbed carbon dioxide and water into glucose (a type of sugar) and oxygen.

5. The glucose is used by the plant for growth and energy, while the oxygen is released back into the atmosphere.

6. Some of the glucose is also converted back into water, which is used in the next cycle of photosynthesis.

This process is crucial for life on Earth as it is the primary source of oxygen in the atmosphere.
