Question

What is the female part of a flower known as?
(a) Pistil
(b) Corolla
(c) Stamen
(d)Pollen Tube

Answer 1

Hint: The female part of the plant is divided into three different parts which include stigma, style, and ovary, and helps in the process of fertilization.

Complete answer:
The pistil is the female part of the plant, which contains an expanded basal portion called the ovary, an elongated section called style, and an apical structure that receives pollen called the stigma is present. These all together form the gynoecium or the female reproductive portion of a flower.

Additional information:
-The ovary is an enlarged basal portion which may be located above or below or at the point of junction with the base of the petals and sepals. A locule is a chamber in which the ovules develop.

-Style is a pillar-like stalk through which pollen tubes grow to reach the ovary. Some flowers such as Tulips do not have a distinct style, and the stigma sits directly on the ovary. Whereas in some plants such as lilies, the style is a hollow tube or has transmitting tissues through which the pollen tubes grow.

-Stigma is typically located at the tip of the style, which receives pollen or male gametophytes. They are sticky or feathery to capture pollen.


So, the correct option is, 'Pistil'.

Note:
1. The ontogenetic modification of the shoot apex is being regarded as the floral apex. The shoot is now considered a single unit composed of the stem and leaves; and in that light, it is assumed that development of the flower is “parallel to that of the vegetative shoot, and not as being derived from it”.
2. A megasporophyll is a leaf-like structure that bears megasporangia.
3. Each pistil is constructed from one to many enrolled carpels, each of which encloses one or more ovules. The carpel is a single megasporophyll.
4. An apocarpous flower contains separate pistils (and therefore separate carpels)whereas a syncarpous flower contains a single pistil with two or more united carpels, which is called syncarpous.
