🔬 Mesosome Forms: Tubules vs Lamellae
Mesosomes are infoldings of the plasma membrane found in prokaryotic cells. They come in different structural forms based on their shape:
| Form |
Description |
Structure |
| Tubular Mesosome |
These are tube-like extensions that appear cylindrical and hollow. |
Resemble small pipes or tunnels spreading into the cytoplasm. |
| Lamellar Mesosome |
These are plate-like or sheet-like extensions. |
Resemble stacked membranes or broad, flat folds. |
✅ Key Difference:
While both are extensions of the plasma membrane, tubular mesosomes look like tubes (3D roundish structures), whereas lamellar mesosomes appear like flattened layers or plates.
