PHOTOSYNTHESIS

Photosynthesis

Process by which plants capture energy and make complex molecules (carbohydrates) in a series of linked chemical reactions.

Energy is required for life processes such as: growth & development, movement, transport

Autotrophs – organisms that produce food from sunlight.

Heterotrophs –consume other organisms for energy. Primary consumers Secondary

Photosynthesis occurs in the chloroplasts of plants.

Absorbs light energy It reflects green wavelengths of light (this

is why plants are green)
