tissues are layers of similar cells. the outside layer of a leaf is called the epidermis tissue. the epidermis is made of flat cells . this layer is like the top layer of your skin. it protects the plant.
Typically, the waxy layer of a leaf, known as the cuticle, is thinner than the epidermis. The cuticle is a thin, waterproof layer that helps prevent water loss from the leaf, while the epidermis is a thicker layer of cells that provides protection and support to the leaf.
Palisade cells are typically found in the upper layer of a leaf called the palisade mesophyll. They are located directly beneath the upper epidermis and are responsible for carrying out photosynthesis due to their high concentration of chloroplasts.
the outside layer of flat cells is the epidermis.
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.
There are 4 layers to the typical leaf; the upper epidermis, palisade layer, spongy layer and lower epidermis. ref http://users.rcn.com/jkimball.ma.ultranet/Biology/Pages/L/Leaf.html
