Why do C4 plants have a higher photosynthetic rate because?
Why do C4 plants have a higher photosynthetic rate because?
Most C4 plants are native to the tropics and warm temperate zones with high light intensity and high temperature. Under these conditions, C4 plants exhibit higher photosynthetic and growth rates due to gains in the water, carbon and nitrogen efficiency uses.
What is the rate of photosynthesis in C4 plants?
C4 Photosynthesis
| Parameter | C3 | C4 |
|---|---|---|
| Maximum daily production rate | 10–40 | 40–80 |
| Maximum biomass yield | 1–5 | 3–14 |
| Photosynthetic thermal optimum | 15–30 | 30–40 |
| Photorespiration/Photosynthesis @ 10 °C | 8% | 1–5% |
What is the difference between C3 and C4 pathway?
C3 plants are defined as the plants that exhibit the C3 pathway. On the other hand, C4 plants are defined as the plants that use the C4 pathway or Hatch-slack pathway during the dark reaction. The leaves possess kranz anatomy, and the chloroplasts of these plants are dimorphic.
Is Arabidopsis a C3 or C4?
The short-term response of Arabidopsis thaliana (C3) and Zea mays (C4) chloroplasts to red and far red light. Planta.
What does C3 and C4 mean in photosynthesis?
C3 and C4 photosynthesis The majority of plants and crop plants are C3 plants, referring to the fact that the first carbon compound produced during photosynthesis contains three carbon atoms. Under high temperature and light, however, oxygen has a high affinity for the photosynthetic enzyme Rubisco.
Can a C3 plant be turned into a C4 plant?
Therefore engineering C4 feature into C3 plants has been suggested as a feasible way to increase photosynthesis and yield of C3 plants, such as rice, wheat, and potato. To identify the possible transition from C3 to C4 plants, the systematic comparison of C3 and C4 metabolism is necessary.
How is the C3 cycle different from the C4 cycle?
Concentration of oxygen does not have any inhibitory role in C4 cycle. C3 cycle requires 18 ATP molecules to synthesize one molecule of glucose. C4 cycle requires 30 ATP molecules to synthesize one molecule of glucose. The complete steps of C3 cycle are executed in the mesophyll cells only.
Why does oxygen reduce the efficiency of C3 photosynthesis?
Under high temperature and light, however, oxygen has a high affinity for the photosynthetic enzyme Rubisco. Oxygen can bind to Rubisco instead of carbon dioxide, and through a process called photorespiration, oxygen reduces C3 plant photosynthetic efficiency and water use efficiency.
