Petiole is also called as leaf stalk. | Lamina is also called as leaf blade and it is flattened part of the leaf. |
2. | The leaf and stem are attached together by the petiole and contains vascular tissue. |
Lamina of the plant is of flat structure and contains chloroplast and the stomata which are made up of mesophyll tissue. |
3. |
Vascular tissues are present in the petiole of the plant. | Mesophyll is present in the lamina of the plant. |
4. | Petiole in the plant is responsible for the connection between stem and leaf. Photosynthesis process give products (carbohydrates) and are transported from leaf to the other parts of the plants. |
The photosynthesis process occurs on the surface of the leaf which is known as lamina. Plants produce their own food by the photosynthesis process. Lamina give large area for the photosynthesis process. |
