Over time, what would we expect in the evolution of C3, C4, and CAM strategies?
A) As the most complicated plants, CAM plants are most likely to go extinct.
B) As the probable ancestral form of photosynthesis, C3 plants are primitive and most likely to go extinct.
C) Because CAM plants make better usage of metabolism during the night, they are superior and will eventually become the dominant plants.
D) Because CO2 is delivered by the bundle sheath cells in C4 plants, they are superior and will eventually dominate.
E) Each form of photosynthesis has advantages in a heterogeneous world and, as long as environmental conditions vary, all forms will have an adaptive advantage in their unique niche.
CAM Strategies
CAM strategies refer to Crassulacean Acid Metabolism, a photosynthetic adaptation used by some plants to minimize water loss by fixing CO2 at night.
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water, generating oxygen as a byproduct.
Evolution
The process through which species of organisms undergo changes over time through genetic variation and natural selection.
- Understand the basic principles and differences among various photosynthetic strategies (e.g., C3, C4, CAM).
- Identify the evolutionary significance of different photosynthesis strategies in a changing environment.
