Stomatal Function
Game Objective:
Discover how light intensity and CO₂ levels affect stomatal opening in plant leaves.
Scientific Principles:
• Stomata open in response to blue light detected by phototropins
• Low CO₂ concentrations inside the leaf trigger opening
• Guard cells swell when turgid, creating the stomatal pore
