What is the difference between a palisade tissue and a mesophyll cell?
Palisade mesophyll
Spongy mesophyll
1. The palisade layer is found below the upper epidermis. | 1. The spongy mesophyll is found towards the lower epidermis |
2. Cells compactly arranged at right angle to the epidermis. | 2. Cells are with large inter cellular space. |
3. These cells possess large concentration of chloroplast. | 3. The cells possess chloroplast but three to four times lesser than the palisade tissue. |
4. Mainly meant for photosynthesis and as a result food is produced. | 4. The main function is buoyancy and exchange of water vapour. |
5. Possess irregular or isodiametrical cells. | 5. Possess elongated columnar cells. |
6. Non-living inclusions are found in this layer. | 6. Non-living inclusions are completely absent. |
