Question

Each female flower consists of
A. Ovary
B. Stigma
C. Ovary, style, and stigma
D. Thalamus

Answer 1

Hint:- Angiosperms are the foremost developed variety of plants among the full kingdom Plantae. They are also called as flowering plants showing sexual reproduction (amphimixis).
Much before the particular flower is seen on a plant, the decision that the plant going to flower has taken place. Several hormonal and structural changes are initiated which cause the differentiation and further development of the flower.

Complete Answer:-
The flower contains a stalk called a pedicel. The free end of the pedicel is flattened or dome-shaped which is termed as the thalamus. The thalamus could be a form of modified stem on which nodes and internodes are present.
The petals, sepals and the reproductive parts of a flower, all are arranged on the thalamus.
Thus the thalamus is found in both male and female flowers.
Female reproductive part of a flower is additionally called gynoecium (pistil).
The gynoecium may be of two types. It may encompass a single pistil (monocarpellary) or may have more than one pistil (multicarpellary). When there are more than one, the pistils could also be fused (syncarpous) or could also be free (apocarpous).
Each pistil has three parts named as - stigma, style and ovary. The stigma is a landing platform for pollen grains. The style is the elongated slender part located beneath the stigma. The basal bulged part of the pistil is called the ovary. Inside the ovary, is the ovarian cavity (locule). The placenta is located inside the ovarian cavity. Ovules (megasporangia) arise from the placenta. The number of ovules in an ovary may be one or more than one.
Thus, the right option is C.

Note:- During the process of pollination, pollen grains from the anther are released and they come in contact with stigma with various methods or with the help of various pollinating agents.
After pollination, pollen grains germinate on the stigma. They absorb moisture and sugar content from the stigma and swell up. The inner thin layer of pollen grain ultimately develops into a pollen tube. Pollen tubes then produce certain enzymes which digest the tissue of stigma and solid style.
