Process map by Brian. 38 steps, 3 layers. Tags: science, biology, plants.
- The Sun: Sunlight streams toward Earth
- The plant: Roots drink water up from the soil
- The plant: Leaf opens its stomata to breathe in CO2
- Leaf cell: Enough water and CO2 on hand?
- Chloroplast: Capture the light with chlorophyll
- Chloroplast: Build sugar from CO2 in the Calvin cycle
- Leaf cell: More sugar than the plant needs right now?
- Leaf cell: Store the extra as starch
- The plant: Exhale oxygen through the stomata
- The plant: A green, growing plant quietly feeding the planet
- Leaf cell: Burn sugar now for growth and repair
- The plant: Close the stomata to stop losing water
