Study Notes
Alternative Pathways
- C4 plants partially close their stomata during the hottest part of the day.
- C4 plants use enzymes to convert carbon dioxide to four-carbon compounds instead of three-carbon compounds, allowing them to photosynthesize efficiently despite low carbon dioxide levels.
- Corn and sugarcane are examples of C4 plants.
- CAM plants open their stomata at night and close them during the day.
- At night, CAM plants take in carbon dioxide and fix it to organic compounds to be used for photosynthesis during the day.
Factors that Affect Photosynthesis
- Light intensity directly affects the rate of photosynthesis.
- As light intensity increases, so does the rate of photosynthesis.
- However, there is a point where increasing light intensity has no further effect on the rate of photosynthesis.
- Carbon dioxide levels also influence the rate of photosynthesis.
- Increasing carbon dioxide levels increases the rate of photosynthesis up to a certain point.
- Temperature plays a crucial role in the rate of photosynthesis.
- There is an optimal temperature where the rate of photosynthesis is highest.
- When temperatures go above or below this optimal temperature, the rate of photosynthesis decreases.
