What are the internal parts of a leaf? Plant Family. A leaf is a plant organ that is flat, thin and usually green in color. Coniferous plant species that thrive in cold environments, such as spruce, fir, and pine, have leaves that are reduced in size and needle-like in appearance. The scaly stipules which occur on ventral side of petiole and enclose and protect the vegetative buds during early stages of development, and fall-off soon after the leaf primordia enlarge and unfold, e.g., Magnolia, Ficus, Ricinus etc. These are modified into tendrils. Stipules are the lateral appendages of the leaf borne at its base. This sheathing leaf base is of frequent occurrence among monocotyledons. This Elodea leaf cell exemplifies a typical plant cell. In banana, sheathing of many leafs jointly makes a stem like structure known as false stem (pseudostem). It is of two types – Reticulate and Parallel.
