Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Detailed explanation-3: -Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air. Photosynthesis starts when chlorophyll absorbs energy from sunlight.

Detailed explanation-4: -Five key factors determine a plant’s ability to photosynthesize: sunlight, carbon dioxide, water, soil organisms, and nutrients.

Detailed explanation-5: -Water is responsible for cell structural support in many plants, creating a constant pressure on cell walls called turgor, which makes the plant flexible yet strong and allows it to bend in the wind or move leaves toward the sun to maximize photosynthesis.
