Give comparison between the following:
Anatomy of leaf in C3 and C4 plants
Advertisements
उत्तर
| C3 leaves | C4 leaves | |
| 1. | The leaves do not possess kranz anatomy. | The leaves have kranz anatomy. |
| 2. | Chloroplasts do not have peripheral reticulum. | Chloroplasts have peripheral reticulum. |
| 3. | Chloroplast are of one type (monomorphic) | There are two types of chloroplasts (dimorphic). |
| 4. | Bundle sheath cell usually do not contain chloroplast. | Bundle sheath cells posses promient chloroplast. |
| 5. | In higher plants operating C3 cycle, all the chloroplasts are granal. | There are two types of chloroplasts, granular in mesophy II cells and agranal in bundle sheath cells. |
| 6. | Mesophy II cell perform complete photosynthesis. | Mesophy II cells perform only initial fixation. |
| 7. | Perform photosynthesis only when stomata are open. | Perform photosynthesis even when stomata is closed (from CO2 produced in respiration). |
