Detailed explanation-1: -The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style.
Detailed explanation-2: -The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules.
Detailed explanation-3: -The four main parts of a flower are the petals, sepals, stamen, and carpel (sometimes known as a pistil). If a flower has all four of these key parts, it is considered to be a complete flower. If any one of these elements is missing, it is an incomplete flower.
Detailed explanation-4: -Female flowers have pistils and male flowers have stamens. An easy way to remember is that stamen has the word “men” in it. A pistil consists of three parts: the stigma, style, and ovary.
Detailed explanation-5: -Pistil is the name of the female floral organ. The pistil consists of a long cylindrical central part, called a style, that connects the lower ovary to the upper stigma, which receives and holds pollen. There may be a single pistil, as in the lily, or several to many pistils, as in the buttercup.
