The Bundle sheath cells are rich in -------- while lacks----.
- a)RuBisCo, PEPCase
- b)PEPCase, RuBisCo
- c)ATPase, Hydrolase
- d)Hydrolase, ATPase
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The Bundle sheath cells are rich in -------- while lacks----.a)RuBisCo...
The Bundle sheath cells are rich in RuBisCo while lacks PEPCase.
- RuBisCo: Enzyme responsible for carbon fixation in the Calvin cycle.
- PEPCase: Enzyme involved in C4 photosynthesis, found in mesophyll cells.
In C4 plants, Bundle sheath cells possess RuBisCo for the Calvin cycle, while PEPCase is located in mesophyll cells where initial carbon fixation occurs. This spatial separation enhances efficiency by concentrating CO2 for RuBisCo in Bundle sheath cells.

Introduction to Bundle Sheath Cells
Bundle sheath cells are specialized plant cells found in the vascular tissue of leaves. They play a crucial role in photosynthesis, especially in C4 plants.
Characteristics of Bundle Sheath Cells
- Rich in RuBisCo:
- Bundle sheath cells contain high concentrations of RuBisCo (Ribulose-1,5-bisphosphate carboxylase/oxygenase), an essential enzyme for the Calvin cycle.
- RuBisCo catalyzes the fixation of carbon dioxide, making it vital for carbon assimilation.
- Lacks PEPCase:
- These cells do not produce PEPCase (Phosphoenolpyruvate carboxylase), which is involved in the initial fixation of carbon dioxide in C4 photosynthesis.
- PEPCase operates primarily in mesophyll cells, where the first steps of carbon fixation occur.
Function of Bundle Sheath Cells
- Photosynthesis:
- In C4 plants, the bundle sheath cells are crucial for the Calvin cycle, where they utilize the products of the mesophyll cells.
- Spatial Separation:
- C4 plants separate the processes of carbon fixation and the Calvin cycle spatially, allowing for more efficient photosynthesis in hot, dry conditions.
Conclusion
Understanding the composition of bundle sheath cells is critical for grasping the efficiency and mechanisms behind C4 photosynthesis. Their richness in RuBisCo and absence of PEPCase illustrate their specialized function in carbon fixation and the overall photosynthetic process. This distinction is essential for studies related to plant physiology and adaptations to environmental conditions, making option 'A' the correct answer.
