C4 has two features that are advantages in warm, dry environments.

C4 has two features that are advantages in warm, dry environments. Suppression of photorespiration (more C gain) 2. Lower stomatal conductance (less water loss) C4 plants can achieve high photosynthetic rates at lower stomatal conductance than C3 plants. How?. C4. C3. Photo- synthesis.

Alternative Mechanisms of Carbon Fixation

Alternative Mechanisms of Carbon Fixation. Stomata. Allow for the entry of CO 2 and exit of water vapor (transpiration). On sunny, hot, dry days, guard cells close to preserve water, but this poses a problem for photosynthesis.

Special Adaptations of C 4 and CAM Plants (Unit 7.12)

Special Adaptations of C 4 and CAM Plants (Unit 7.12). James Michael Shefali. C 3 Plants. C 3 plants absorb the carbon dioxide they use in the Calvin Cycle directly from the atmosphere; this means that they must keep their stomata open most of the time despite the water loss this entails.
