(N/A) typical flower consists of four whorls arranged on the thalamus. These are categorized into two sterile whorls and two fertile whorls.
$1$. Sterile Whorls:
- Calyx: The outermost whorl consisting of sepals,which protect the flower in the bud stage.
- Corolla: The second whorl consisting of petals,which are often brightly colored to attract pollinators.
$2$. Fertile Whorls:
- Androecium: The male reproductive whorl consisting of stamens. Each stamen has a filament (stalk) and an anther (pollen-bearing part). The connective tissue joins the anther lobes to the filament.
- Gynoecium: The innermost female reproductive whorl consisting of one or more carpels (pistils). Each carpel consists of three parts: the ovary (basal swollen part containing ovules),the style (elongated tube),and the stigma (terminal part that receives pollen grains).
