Process
Photosynthesis
Using light energy to turn carbon dioxide and water into sugar, releasing oxygen.
Plant Lab
Follow water, sugar and gases through a plant, test what limits photosynthesis, and match hormones to their effects.

How this step works
- Open the Plant Lab and work through it at your own pace.
- Come back here and mark the lab as done.
Lab XP is earned once per lab. If another path includes the same lab, finishing it here counts there too.
Concepts you will meet
Structure
Xylem and phloem
Xylem carries water up from the roots; phloem carries sugars from leaves to where they are used or stored.
Structure
Stomata
Adjustable leaf pores that let carbon dioxide in and water vapor out.
Structure
Chloroplasts
Capture light energy to make sugar by photosynthesis.
Molecule
Plant hormones
Chemical signals such as auxin and abscisic acid that coordinate plant growth and responses.
Process
Pollination
Moving pollen between flowers, often by animals, so plants can make seeds.
Molecule
Rubisco
The enzyme that captures carbon dioxide in photosynthesis, often called the most abundant protein on Earth.
