Factors that affect photosynthetic rate (5.2) Flashcards
State what the opening of the stomata controls
- loss of water
- entry of carbon dioxide
Describe C3 plants
Rely on Calvin cycle (carbon fixation pathway) to convert CO2 into an organic compound
State the effect of limited inputs on photosynthetic rate
If any one of the 3 required inputs is limited, photosynthesis will be limited
Describe the relationship between light intensity and photosynthetic rate
Photosynthetic rate increases with an increase in light intensity until a point of saturation
Describe the relationship between carbon dioxide concentration and photosynthetic rate
Photosynthetic rate increases with an increase in carbon dioxide levels
Describe the relationship between temperature and photosynthetic rate
Photosynthetic rate increases with an increase in temperature until the optimal temperature range is reached
Describe the effect of chloroplast availability on photosynthetic rate
Low chloroplast availability will limit photosynthetic reaction rate
State the reactants of photosynthesis
Water and CO2
State the products of photosynthesis
Glucose, oxygen and water
