Question
Where do the light-independent reactions take place in C3 photosynthesis? Mesophyll cells during the daytime Bundle-sheath cells at night Where do the light-independent reactions take place in C4 photosynthesis? Mesophyll cells at night Bundle-sheath cells during the daytime Where do the light-independent reactions take place in CAM photosynthesis? Mesophyll cells during the day Bundle-sheath cells at night In oceans, a large amount of photosynthesis is done by single-celled diatoms. In parts of the ocean, CO_2 concentrations are very low. A few years ago, scientists discovered an adaptation in some diatoms for photosynthesizing under low CO_2 conditions. Which of these might that be? Smaller stomata C3 photosynthesis C4 photosynthesis High photorespiration Diatoms are single-celled algae that are one of the major photosynthesizers in the oceans. There are numerous species of diatoms. Some have adaptations that allow them to deal with low CO_2 concentrations in some areas of the ocean.Explanation / Answer
56. In C3 plants, carbon fixation and photosynthesis occur in bundle sheath during night time on the surface of leaf. This is because of stomata, which plays a role in this process. Hence, the correct option is bundle sheath cells at night.
57. Light independent reactions associated with C4 occur in mesophyll cells at night time.
