The cross section of a typical leaf is divisible into three main parts namely, the Epidermis, Mesophyll, and the Veins. The Epidermis is made of several layers of cells that are sandwiched between two layers. The Epidermis protects the tissues which lie between them and also helps in the process of gaseous exchange. Epidermis is further divisible into two types called, the Upper Epidermis and the Lower Epidermis. Beneath the Epidermis is the Mesophyll where Photosynthesis takes place. Photosynthesis is the process by which plants make their own food like sugars & amino acids. The Veins (surrounded by the Bundle sheath cells) provides the necessary support to the leaf in the transport of water and plant food to other parts of the plant. The Stoma located in the Lower Epidermis is an opening that control the gaseous exchange that occurs between the leaf and the atmosphere during photosynthesis. The gas exchange involves the use of common gas like Carbon Dioxide and Oxygen. | 0.690094 |

Epidermis | d | DD_0107 | image | teaching_images/parts_leaf_3854.png | The diagram shows the main parts of a cross section of a typical plant leaf. The cross section of a typical leaf is divisible into three main parts namely, the Epidermis, Mesophyll, and the Veins. The Epidermis is made of several layers of cells that are sandwiched between two layers. The Epidermis protects the tissues which lie between them and also helps in the process of gaseous exchange. Epidermis is further divisible into two types called, the Upper Epidermis and the Lower Epidermis. Beneath the Epidermis is the Mesophyll where Photosynthesis takes place. Photosynthesis is the process by which plants make their own food like sugars & amino acids. The Veins (surrounded by the Bundle sheath cells) provides the necessary support to the leaf in the transport of water and plant food to other parts of the plant. The Stoma located in the Lower Epidermis is an opening that control the gaseous exchange that occurs between the leaf and the atmosphere during photosynthesis. The gas exchange involves the use of common gas like Carbon Dioxide and Oxygen. | 0.690094 |
