Question:

''Kranz anatomy'' is present in

Options:

1. All photosynthetic plants
2. Only C₃ plants
3. Only succulent plants
4. Only C₄ plants

Solution:

''Kranz anatomy'' refers to a special leaf anatomy found in some plants, especially C₄ plants. It is characterized by the presence of a ring of bundle sheath cells surrounding the leaf veins. This ring of cells contains numerous chloroplasts and is responsible for the majority of the CO₂ fixation in C₄ plants. Kranz anatomy is not found in all photosynthetic plants, nor is it limited to succulent plants. It is a specialized adaptation to increase the efficiency of carbon fixation in C₄ plants, which are typically found in hot, dry environments.
