Photosynthesis

process in which plants produce food using light

Equation for photosynthesis:

Carbon dioxide + Water → Glucose + Oxygen

Factors that affect photosynthesis

Water, carbon dioxide, light, chlorophyll

How does carbon dioxide affect photosynthesis?

Needed to produce glucose, the excess glucose is stored as starch (carbohydrates).

Water

Enters through roots, stem and leaves, needed for photosynthesis.

Light

Plant’s main energy source for photosynthesis.

Chlorophyll

The green pigment in plants that captures light energy for photosynthesis.

Products of photosynthesis:

Glucose (Carbohydrates) and oxygen

Glucose in photosynthesis:

Main product of photosynthesis, soluble in water, excess is stored as insoluble starch.
