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 ...
Secondly, plant morphology observes both the vegetative (somatic) structures of plants, as well as the reproductive structures. The vegetative structures of vascular plants includes the study of the shoot system, composed of stems and leaves, as well as the root system.
Sexual systems play a key role in genetic variation and reproductive success, and may also have led to the origin or extinction of certain species. [4] In flowering plants and animals, sexual reproduction involves meiosis , an adaptive process for repairing damage in the germline DNA transmitted to progeny. [ 5 ]
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.
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: [28] K = calyx; for example, "K5" indicates that the flower has 5 sepals. C = corolla; for example, "C3" means that the flower has 3 ...
Phytoestrogens are not essential nutrients because their absence from the diet does not cause a disease, nor are they known to participate in any normal biological function. [2] Common foods containing phytoestrogens are soy protein , beans , oats , barley , rice , coffee , apples , carrots (see Food Sources section below for bigger list).
Plant morphology is the field in botany that studies the diversity in forms, with the naked eye or slight optical magnification. This is opposed to plant anatomy (see Category:Plant anatomy ) that needs to cut into plants to be able to study its subject, usually with a microscope.
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
