Epiphytic root – This type of root seen in epiphytic orchids. The thick root hangs from the plant's base directly into air. The root is covered with a special, usually 4- to 5-cell layer thick, [12] spongy tissue (called Velamen), which helps the plant to absorb moisture from the atmosphere. Epiphytic orchid have another sort of root, called ...
The protective external layer of tissue on the stem s and root s of woody trees and shrubs; includes all of the living and non-living tissue external to the cambium. basal Situated or attached at or close to the base (of a plant or a phylogenetic tree diagram). basifixed Something attached by its base, e.g. an anther attached to the filament.
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, engages in photosynthesis, stores nutrients, and produces new living tissue.

A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. [5] [6] Rhizomes have nodes and internodes and auxiliary buds. [7] Roots do not have nodes and internodes and have a root cap terminating their ends. [8]
The Liliaceae are characterised as monocotyledonous, perennial, herbaceous, bulbous (or rhizomatous in the case of Medeoleae) [7] flowering plants with simple trichomes (root hairs) and contractile roots. [8] The flowers may be arranged (inflorescence) along the stem, developing from the base, or as a single flower at the tip of the stem, or as ...
The vegetative (somatic) structures of vascular plants include two major organ systems: (1) a shoot system, composed of stems and leaves, and (2) a root system. These two systems are common to nearly all vascular plants, and provide a unifying theme for the study of plant morphology.
Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant. [22] Examples of stem tubers are potatoes and yams and examples of root tubers are sweet potatoes and ...
The edible portion is stem tissue. The fig "fruit" is actually an inverted flower cluster with both the male and female flower parts enclosed inside the base of the inflorescence, corresponding to the peduncle. Ginger root The edible portion is a branched underground compressed stem also referred to as a rhizome. Kohlrabi
