Factors Affecting Photosynthesis Rates in Autotrophs

Front

Factors affecting photosynthesis

Back

Light intensity, carbon dioxide concentration, temperature

Front

Light intensity

Back

Higher light intensity increases photosynthesis rate

Front

Carbon dioxide concentration

Back

Higher CO2 concentration increases photosynthesis rate

Front

Temperature

Back

Optimal temperature range increases photosynthesis rate

Front

Suboptimal temperature (anything below what the plant prefers or functions best at)

Back

Decreases photosynthesis rate
