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 ...
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 ...
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae ).

Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of ...
