Question
Which of the following is not a C4 plant?
- Sugarcane
- Maize
- Sorghum
- Rice
Hint:
C4 plants are defined as the plants that use the C4 pathway or Hatch-Slack pathway during the dark reaction.
The correct answer is: Rice
C4 plants are defined as the plants that use the C4 pathway or Hatch-Slack pathway during the dark reaction.
Examples for C4 plants: corn, sugarcane, amaranth, mostly grasses, but some shrubs too, which are cold tolerant.
So Rice is not a C4 plant because Rice has a C3 photosynthetic pathway
