photosynthesis

The process described, where a plant cell takes in carbon dioxide (CO2), sunlight, and water to produce its own sugar and give off oxygen, is called photosynthesis.

The correct answer is photosynthesis.

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose (sugar). This process takes place in the chloroplasts of plant cells. During photosynthesis, plants use carbon dioxide (CO2) from the atmosphere, water (H2O) from the soil, and sunlight to produce glucose (C6H12O6) and oxygen (O2). This glucose serves as a source of energy for the plant, while oxygen is released into the environment as a byproduct.

To obtain this answer, you can remember the key components and steps of photosynthesis:

1. Carbon dioxide (CO2): Plants take in carbon dioxide from the atmosphere. This gas enters through small openings on the leaves called stomata.

2. Water (H2O): Plants absorb water through their roots from the soil, which is then transported to the leaves through specialized tissues called xylem.

3. Sunlight: The energy needed for photosynthesis comes from sunlight. Plants capture light using a molecule called chlorophyll, which is found in chloroplasts.

4. Chloroplasts: These organelles are responsible for photosynthesis. They contain chlorophyll and other pigments that absorb light energy.

5. Glucose production: Using the energy from sunlight, plants convert carbon dioxide and water into glucose (sugar). This process occurs in the chloroplasts, specifically in a series of chemical reactions called the Calvin cycle.

6. Oxygen release: As a byproduct of photosynthesis, plants release oxygen into the atmosphere through the stomata.

Remembering these key points will help you understand and recall the process of photosynthesis and its importance in the production of oxygen and sugar in plants.
