Difference between Mesophyll Cells and Bundle Sheath Cells
Mesophyll cells are located in the leaf’s interior, and responsible for initial CO2 fixation in C4 plants, while bundle sheath cells surround vascular bundles, facilitating the Calvin cycle and minimizing photorespiration. Here are some key differences,
Characteristic |
Mesophyll Cells |
Bundle Sheath Cells |
---|---|---|
Location |
Interior tissue of the leaf (mesophyll layer) |
Surrounding vascular bundles within the leaf |
Chloroplast Density |
Contains chloroplasts, less densely packed |
High concentration of chloroplasts, densely packed |
Cell Arrangement |
Loosely packed, irregular shape |
Tightly packed, regular shape |
Function in Photosynthesis |
Initial fixation of CO2 into a four-carbon compound |
Site of the Calvin cycle, breakdown of four-carbon compound to release CO2 |
Metabolism |
Involved in C4 pathway and other metabolic processes |
Primarily involved in the Calvin cycle |
Adaptations to Environment |
Adapted for gas exchange and light absorption |
Adapted to minimize photorespiration and maximize carbon fixation efficiency |
Kranz Anatomy – An Overview
Kranz Anatomy is a distinctive arrangement found in C4 plants, characterized by mesophyll cells forming a ring around the bundle-sheath cells. Kranz Anatomy is found in angiosperms like sugarcane and grasses which undergo C4 photosynthesis. Plants growing in warm tropical or arid environments have developed this efficient photosynthetic pathway. Let us discuss Kranz’s anatomy in detail.
