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 ...
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 ...
Floral morphology. 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 ...
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 ...
Complete – of a flower, having all the possible parts represented: sepals, petals, stamens, and pistils. Gynodioecy – describes a plant species or population that has some plants that are female and some plants that are hermaphrodites. Homogamous – when the flower's anthers and stigma are ripe at the same time.
Pollen grain Hibiscus flower. Flower colour in certain species, such as H. mutabilis and H. tiliaceus, changes with age. [9] The fruit is a dry five-lobed capsule, containing several seeds in each lobe, which are released when the capsule dehisces (splits open) at maturity. It is of red and white colours. It is an example of complete flowers.
The reproductive parts of an orchid flower are unique in that the stamens and style are joined to form a single structure, the column. [ 10 ] [ 11 ] [ 12 ] Instead of being released singly, thousands of pollen grains are contained in one or two bundles called pollinia that are attached to a sticky disc near the top of the column.
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 ...
