Study Notes
C3 and C4 Plants
- The main difference between C3 and C4 plants is the initial carbon fixation site: mesophyll cells in C3 plants and mesophyll cells followed by bundle-sheath cells in C4 plants.
C4 Plant Characteristics
- Initial carbon fixation occurs in mesophyll cells, followed by the Calvin cycle in bundle-sheath cells in C4 plants.
- C4 plants are more efficient in hot and dry conditions.
- A disadvantage of the C4 pathway is the higher energy requirement compared to the C3 pathway.
CAM Plants
- CAM (Crassulacean Acid Metabolism) plants are known for minimizing water loss by opening stomata at night and fixing carbon dioxide into organic acids.
Common Features and Differences
- A common feature among C3, C4, and CAM plants is their ability to perform photosynthesis.
- C3, C4, and CAM plants are distinguished by their carbon fixation mechanisms and adaptations to environmental conditions.
- The primary advantage of C4 plants over C3 plants is their increased efficiency in hot and dry conditions.
