NEETBotanyPhotosynthesis in Higher Plants
Adaptations of C4 Plants Functions A. Bundle Sheath Cells 1. Have thick walls that are impervious to gaseous exchange and contain many chloroplasts. B. Mesophyll Cells 2. Found surrounding the bundle sheath cells and are involved in the initial fixation of CO2. C. Efficient Carbon Fixation 3. Results from the lack of photorespiration and the presence of specialized leaf anatomy. D. Lack of Intercellular Spaces 4. Hel
Options
- AA - 4, B - 2, C - 3, D - 1
- BA - 2, B - 1, C - 4, D - 3
- CA - 1, B - 4, C - 2, D - 3
- DA - 2, B - 3, C - 4, D - 1
Correct answer
A. A - 4, B - 2, C - 3, D - 1
Step-by-step solution
A - 4: The lack of intercellular spaces in bundle sheath cells helps in reducing CO2 loss and preventing photorespiration. B - 2: Mesophyll cells are responsible for the initial fixation of CO2 in C4 plants. C - 3: C4 plants achieve efficient carbon fixation due to their lack of photorespiration and specialized leaf structure. D- 1: Bundle sheath cells in C4 plants have thick walls and are rich in chloroplasts, forming a key part of the Kranz anatomy.
