How are C3 and C4 plants similar and different?
C3 plants use the C3 pathway or Calvin cycle for the dark reaction of photosynthesis. C4 plants use the C4 pathway or Hatch-Slack Pathway for the dark reaction of photosynthesis. These plants are cool-season plants, commonly found in cool and wet areas. These plants are warm-season plants, commonly found in dry areas.
Which best describes a difference between C3 and C4 plants?
In C3 plants, the bundle sheath cells do not contain chloroplasts. In C4 plants, the bundle sheath cells contain chloroplasts. In C3 plants, the carbon dioxide fixation takes place only at one place. In C4 plants, the carbon dioxide fixation takes places twice (one in mesophyll cells, second in bundle sheath cells).
What are the similarities and differences between C4 and CAM plants?
C4 vs CAM Plants The main difference between C4 and CAM plants is the way they minimize water loss. C4 plants relocate the CO2 molecules to minimize photorespiration while CAM plants choose when to extract CO2 from the environment.
What differences exist in C3 and C4 plants anatomy and pathway of photosynthesis?
In C4 plants, the bundle sheath cells contain chloroplasts. In C3 plants, the carbon dioxide fixation takes place only at one place. In C4 plants, the carbon dioxide fixation takes places twice (one in mesophyll cells, second in bundle sheath cells). C3 plants possess only one CO2 acceptor.
What is the difference between C3 and C4 photosynthesis?
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

What is the difference between C3 and C4 cycle?
How do C4 plants differ from C3 plants quizlet?
The leaves of C4 plants have more prominent bundle sheath cells than the leaves of C3 plants. Another important difference is that the Calvin cycle takes place in the bundle sheath cells of C4 plants whereas the Calvin cycle takes place in the mesophyll cells of C3 plants.
Why are C4 plants more efficient than C3 plants?
C4 plants are more efficient than C3 due to their high rate of photosynthesis and reduced rate of photorespiration. The main enzyme of carbon fixation (Calvin cycle) is RuBisCO.
Which is more efficient, a C3 or a C4 plant?
The C4 pathway is certainly more efficient than the C3 pathway in the sense of carbon fixation. The enzyme responsible for this step is RuBisCO. In C4 plants, the inner cells get only carbon dioxide in the form of malate. This avoids the oxygenation process and, hence, makes this pathway more efficient.
Why efficiency of C4 plants is more than C3 plants?
The C4 plants are considered to be more productive than the C3 plants because they lack the phenomenon of photorespiration. They also have the mechanism to increase the CO. C4 acids are broken in the bundle sheath cells to release CO2, thus increasing the intracellular concentration of CO2
What are some good examples of C3 and C4 plants?
