Stomatal Response to Light
Observe Guard Cell Behavior Under Different Light Conditions
Investigate how light intensity affects stomatal opening in leaf epidermis. Adjust the light levels and observe changes in stomatal aperture under the microscope.

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
