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.
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.
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 ...
Consistent with the three modes of fruit development, plant scientists have classified fruits into three main groups: simple fruits, aggregate fruits, and multiple (or composite) fruits. [15] The groupings reflect how the ovary and other flower organs are arranged and how the fruits develop, but they are not evolutionarily relevant as diverse ...
Fasciculated root (tuberous root) occur in clusters at the base of the stem; examples: asparagus, dahlia. Nodulose roots become swollen near the tips; example: turmeric. Brace roots arise from the first few nodes of the stem. These penetrate obliquely down into the soil and give support to the plant; examples: maize, sugarcane. Prop roots give ...
Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam. The term root tuber describes modified lateral roots , as in sweet potatoes , cassava , and dahlias .
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]
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.
