Explain the parts of a flower, with a neat labelled diagram.

Explanation

In a plant, which part would you like the most? Of course, it is a flower, because of its colour and fragrance. The flower is a significant diagnostic feature of angiosperms. It is a modified condensed reproductive shoot. The growlh of the flower shoot is determinate. There are two whorls, accessory and essential. Accessory whorl consists of calyx and corolla and essential whorl comprises of androecium and gynoecium. Flower is said to be Complete when it contains all four whorls. An Incomplete flower is devoid of one or more w horls.
(i) Pistil: The female reproductive organ of a flower is Gynoecium or pistil. Each member is carpel
(ii)Petal: innermost accessory whorl of flower is corolla. Each member is called petal.
(iii)Sepal: Outermost whorl of flower is calyx. Each member is called sepal.(iv) Perianth (perigonium), Undifferentiated calyx and corolla. Individual members are called tepal.
(v) Bract: Subtending leaf or leaf like structure of any flower is called Bract.
(vi) Stamen. Male organ of a flower is androecium. Each member is stamen.
(vii) Thalamus (torus or receptacle): The part of the flower on which other floral parts are attached.
(Viii) Bracteole: A smaller bract present on the side of pedicel is called bracteole or bractlet. A whorl of bracteoles at the base of calyx is called epicalyx.
(ix) Pedicel: Stalk of the flower. Flower is pedicellate or sessile depending upon presence or absence. The flowers with a short, rudimentary pedicel are called subsessile flowers.
