Define Gynoecium with its uses_??

$\huge\black{\mid{\fbox{\tt{ANSWER}}\mid}}$

It is the fourth and the last whorl of the flower. Gynoecium is the female reproductive part of the flower which is composed of one or more carpels. Carpels may be free or fused. When the carpels are free (as in lotus and rose) then they are said to be apocarpous and when the carpels are fused (as in mustard and tomato) then they are said to be syncarpous. A carpel has three parts namely.

• Ovary : Ovary is the basal, swollen part of the carpel. It is the lower part of the carpel which bears one or more ovules. These ovules, after fertilisation mature into seeds. The ovules are attached to a flattened, cushion-like structure called placenta. The ovary has one or more chambers or loculi. The ovary containing one chamber is unilocular, two chambers is bilocular, three chamber is triocular and so on. The ovules are borne in these chambers. The wall of the ovary after fertilisation forms the pericarp (fruit wall).

• Style: The tube-like structure which connects the stigma to the ovary is called style. It lies above the ovary in a carpel.
• Stigma : Stigma is generally situated at the tip of the style. Stigma acts as the receptive organ for pollen grains during pollination.

After fertilisation ovules develop into seeds and ovary matures into a fruit.
