A cyclic flower is a flower type formed out of a series of whorls; [1] sets of identical organs attached around the axis at the same point. Most flowers consist of a single whorl of sepals termed a calyx; a single whorl of petals termed a corolla; one or more whorls of stamens (together termed the androecium); and a single whorl of carpels termed the gynoecium.
The morphology of most flowers (called cyclic flowers) is based on four types of whorls: The calyx: zero or more whorls of sepals at the base; The corolla: zero or more whorls of petals above the calyx; The androecium: zero or more whorls of stamens, each comprising a filament and an anther
The weed-like plants have regular, minute, or small, cyclic flowers. The flowers have no petals, but 5 sepals which are united at the base. It has 5 stamens and the ovary is positioned superior and consists of 2 united carpels. Which late matures into a fruit (or seed capsule). [3]
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.
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
Replacement of a tap root system by a fibrous root is seen in onions, tuberose (Polyanthes tuberosa), grasses, etc. Fibrous roots from normal-stem nodes are seen in grasses like maize, sugarcane, bamboo, etc. Fibrous roots from nodes help in the survival of the plant and thus in vegetative reproduction, when the plant's base is damaged or cut ...

The age of some herbaceous perennial plants can be determined by herbchronology, the analysis of annual growth rings in the secondary root xylem. [18] Herbaceous plants do not produce perennializing above-ground structures using lignin, which is a complex phenolic polymer deposited in the secondary cell wall of all vascular plants. The ...
