Photosynthesis Review

This is the process done by plants, algae, and other autotrophic organisms that get energy from the sun.

Energy from sunlight is captured and stored as sugars.

Multiple Choice

Who does photosynthesis?

• Autotrophs

• Heterotrophs

Leaves: site of most photosynthesis; have stomata, pores to let materials in and out.

Stem: transports material through the plant; water travels through xylem.

Roots: absorb water and nutrients from the soil.
