A flower, also known as a bloom or blossom, 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. These petals attract pollinators, and reproductive organs that produce gametophytes, which in ...
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. [1][2 ...
A floral diagram is a schematic cross-section through a young flower. [1] It may be also defined as “projection of the flower perpendicular to its axis”. [3] It usually shows the number of floral parts, [Note 2] their sizes, relative positions and fusion. Different organs are represented by distinguishable symbols, which may be uniform for ...
The flower-bearing part of the plant is usually sharply distinguished from the leaf-bearing part, and forms a branch-system called an inflorescence. [37] Flowers produce two kinds of reproductive cells. Microspores, which divide to become pollen grains, are the male cells; they are borne in the stamens. [57]
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. [note 1] Fertile leaves or sporophylls carry ...
Leaf margin. Rachis. A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [ 1 ] usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [ 2 ][ 3 ] while the leaves, stem, flower, and fruit collectively form the shoot system. [ 4 ]
Petal. Diagram showing the parts of a mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators.
The large calyx of the medlar fruit is the source of its vulgar nicknames. A sepal (/ ˈsɛpəl, ˈsiːpəl /) [1][2][3] is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. [4]
