Where both bisexual and unisexual flowers exist on the same plant, it is called polygamous. Polygamous plants may have bisexual and staminate flowers (andromonoecious), bisexual and pistillate flowers (gynomonoecious), or both (trimonoecious). Other combinations include the presence of bisexual flowers on some individual plants and staminate on ...
Bearing both male and female reproductive organs; usually, flowers with both stamen s and carpel s; synonymous with hermaphrodite, synoecious, and monoclinous. Bisexual flowers occur only on monoecious plants. See also androgynous, monoicous, and plant reproductive morphology. bitegmic (of an ovule) Covered by two integument s. Contrast unitegmic.
A flower, also known as a bloom or blossom, [1] is the reproductive structure found in flowering plants (plants of the division Angiospermae).Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower.
Unlike (most) animals, plants grow new organs after embryogenesis, including new roots, leaves, and flowers. [3] In the flowering plants, the gynoecium develops in the central region of the flower as a carpel or in groups of fused carpels. [4]
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 ...
Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
A primordium (/ p r aɪ ˈ m ɔːr d i ə m /; pl.: primordia; synonym: anlage) in embryology, is an organ or tissue in its earliest recognizable stage of development. [1] Cells of the primordium are called primordial cells. A primordium is the simplest set of cells capable of triggering growth of the would-be organ and the initial foundation ...
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
