External and internal part of leave?
A leaf normally consists of the following parts: the epidermis, the mesophyll, and the veins. The epidermis cover the upper and lower surfaces (the outside) of the leaf. It contains many types of cell tissues that protect against water loss, regulates the exchange of gases, secretes metabolic compounds and in some leaves controls the absorption of water. The mesophyll, or middle leaf, is where photosynthesis usually occurs. It is often made up of two layers, the palisade and the spongy layers. The veins consist of the Xylem and the Phloem tubes. The Xylem tubes carry water and minerals from the roots to the leaf and the Phloem tubes move sap out of the leaf.
