Scanning electron microscope image of Nicotiana alata leaf's epidermis, showing trichomes (hair-like appendages) and stomata (eye-shaped slits, visible at full resolution) The plant epidermis consists of three main cell types: pavement cells, guard cells and their subsidiary cells that surround the stomata and trichomes, otherwise known as leaf ...
Trichomes (/ ˈ t r aɪ k oʊ m z, ˈ t r ɪ k oʊ m z /; from Ancient Greek τρίχωμα (tríkhōma) 'hair') are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
The stamens sometimes have appendages that form a staminal corona—for example in Hymenocallis. The gynoecium has an ovary in the case of amaryllioids and a superior ovary in agapanthoids and allioids. It is formed by three carpels joined and delimiting three cavities or loculi, which contain from two to three to many anthropoid ovules of ...
In botany, a plant shoot consists of any plant stem together with its appendages like leaves, lateral buds, flowering stems, and flower buds. [1] [2] The new growth from seed germination that grows upward is a shoot where leaves will develop.
In botany, an awn is either a hair- or bristle-like appendage on a larger structure, or in the case of the Asteraceae, a stiff needle-like element of the pappus. Awns are characteristic of various plant families, including Geraniaceae and many grasses ( Poaceae ).
