“Every Flower part serves somepurpose in the making of seeds. Thecolorful, fragrant petals and otherparts of it.”
A flower beauty and perfection of form maybe enjoyed more fully if one understand its structure and how itspart helps in the work of seed making. A typical flower has four sets of organs. From the outside to thecenter, they are: sepals, petals, stamens, and pistils. Theleaf like sepals make up the calyx, or “cup”. The petals fprm the corolla, or “little crown.”
PISTIL-----A flower may have one or more pistils which consist of a basal portion called the ovarywhich contains the embryo seeds called ovules and area where the pollen is received called the stigma. Often the stigma may be borne on a stalk likestructure called the style. The pistil consist of ovule- bearing basic units called carpels. Collectively, the carpels form the gynoecium which is sometimesreferred to as the female part of the flower because the carpels produce the female gametes, but are sometimes incorrectly called female, the correct term is carpellate.
SEPAL----- Usually green , sepals typically functionas protection for the flower in bud, and often assupport for the petals when in bloom,it is aneffective protection against some kinds of birds andinsects is a part of the flower ofangiosperms(flowering plants). Collectively thesepals are called the calyx, the outer most whorl ofparts that form a flower, a cup or a goblet.
STAMEN-----(plural stamina orstamens, from Latin stamen meaning“thread of the wrap”) is the pollenproducing reproductive organ of a flower .stamens typically consist of a stalk calledfilament. Anthers are most commonly two-lobed and are attached to the filamenteither at the base or in the middle portion.The sterile tissue between the lobes is calledthe connective.
PETALS----- are modified leaves thatsurround the reproductive parts of a flowers.They are often brightly colored or unusuallyshaped to attract pollinators. Together , all ofthe petals of a flower are called acorolla, petals are usually accompanied byanother set of special leaves called sepalslying just beneath the corolla. When thepetals and sepals of a flower look similar theyare called tepals.
