Many plants have elaiosomes that attract ants, which take the seed to their nest and feed the elaiosome to their larvae. After the larvae have consumed the elaiosome, the ants take the seed to their waste disposal area, which is rich in nutrients from the ant frass and dead bodies, where the seeds germinate .
The rhytidome is the most familiar part of bark, being the outer layer that covers the trunks of trees. It is composed mostly of dead cells and is produced by the formation of multiple layers of suberized periderm, cortical and phloem tissue. [33] The rhytidome is especially well developed in older stems and roots of trees.
A plant that loses all of its leaves only briefly before growing new ones, so that it is leafless for only a short time, e.g. approximately two weeks. bristle A straight, stiff hair (smooth or with minute teeth); the upper part of an awn (when the latter is bent and has a lower, stouter, and usually twisted part, called the column). brochidodromous
A fir tree snag among living fir trees. In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris.
Rootstock – the underground part of a plant normally referring to a caudex or rhizome. Runner – an above-ground stem, usually rooting and producing new plants at the nodes. Sapwood – Scandent – a stem that climbs. Spine – an adapted leaf that is usually hard and sharp and is used for protection, and occasionally shading, of the plant
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
In plant bodies that produce secondary growth, lenticels promote gas exchange of oxygen, carbon dioxide, and water vapor. [8] Lenticel formation usually begins beneath stomatal complexes during primary growth preceding the development of the first periderm .
The heat is also believed to contribute to the illusion of it being a dead body, to attract carcass-eating insects. [12] Both male and female flowers grow in the same inflorescence. The female flowers open first, and the male flowers open a day or two later. That usually prevents the flower from self-pollinating.
