3 main environmental factors affecting photosynthesis rate
3 main environmental factors affecting photosynthesis rate
Light intensity, carbon dioxide concentration, temperature
Role of light in photosynthesis
Role of light in photosynthesis
Provides energy needed to power photosynthesis
Light saturation point
Light saturation point
When adding more light doesn't increase rate; other factors limit
Role of CO₂ in photosynthesis
Role of CO₂ in photosynthesis
Raw material for glucose production
Why temperature affects photosynthesis differently
Why temperature affects photosynthesis differently
It influences enzyme activity
Effect of high temperature on enzymes
Effect of high temperature on enzymes
Denatures (destroys shape of) enzymes, making them non-functional
Greenhouse definition
Greenhouse definition
Glass/plastic structure trapping heat, allowing light for plants
Greenhouse effect
Greenhouse effect
Natural phenomenon where sun's heat trapped on Earth by CO₂
