Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers , which are the reproductive structures of angiosperms , are the most varied physically and show a correspondingly great diversity ...
Plant morphology treats both the vegetative structures of plants, as well as the reproductive structures. 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 .
In plant taxonomy, which is the study of the classification and identification of plants, the morphology of plant's flowers are used extensively – and have been for thousands of years. Although the history of plant taxonomy extends back to at least around 300 B.C. with the writings of Theophrastus , [ 124 ] the foundation of the modern ...
The most common form of plant reproduction used by people is seeds, but a number of asexual methods are used which are usually enhancements of natural processes, including: cutting, grafting, budding, layering, division, sectioning of rhizomes, roots, tubers, bulbs, stolons, tillers, etc., and artificial propagation by laboratory tissue cloning.
Reproducing through seeds is the most widespread method of reproduction in both monocots and dicots. However, internal seed structure is vastly different between these groups. The cotyledon is the embryonic leaf within a seed; monocots have one whereas dicots have two. The evolution of having one or two cotyledons may have arisen 200-150 Mya ...
The floral formula is a way of symbolically representing the structure of a flower through the use of letters, numbers and other signs. Typically, the floral formula is used to represent the morphological characteristics of the flowers of a given plant family, rather than of a particular species. The following are the most commonly used symbols ...
Herbaceous plants (also called herbs or forbs): a plant whose structures above the surface of the soil, vegetative or reproductive, die back at the end of the annual growing season, and never become woody. While these structures are annual in nature, the plant itself may be annual, biannual, or perennial. Herbaceous plants that survive for more ...
A plant derived from the asexual vegetative reproduction of a parent plant, with both plants having identical genetic compositions. coalescent Having plant parts fused or grown together to form a single unit. cochleariform Concave and spoon-shaped. cochleate Coiled like a snail's shell. coenobium An arranged colony of algae that acts like a ...
