A. Solanaceae
B. Liliaceae
C. Compositae
D. Cruciferae

Answer 1

Hint: Ovary is present mostly in flowering plants and is part of their reproductive organ. It is a part of the pistil and bears ovules. After fertilization the ovary turns into fruits whereas the ovules develop into seeds.

Complete Answer:
- Among the given options each plant family has different forms of ovaries. In the case of Solanaceae family that comprises potatoes, eggplant, tomatoes, petunia, etc. the gynoecium is found to be bicarpelar with a superior ovary and two locules.
- It consists of one style and stigma and the ovary is located in an oblique position with respect to the plane of the flower. In the case of the Liliaceae family that comprises lily, tulip, etc. the ovary is superior with three fused carpels and maybe trilocular or unilocular.
- Along with that it consists of a single style and a three lobed stigma. In the case of Compositae which comprises sunflower, aster, daisy, etc. the ovary is inferior with two fused carpels. It consists of a single style and two lobed stigma.
- In the case of Cruciferae which comprises cabbage, broccoli, rapeseed, etc. the ovary is superior with two fused carpels. Apart from that it consists of a single style and either a single stigma or a two lobed stigma.

So the correct option is A) Solanaceae.

Note: The ovary serves an important role not during fertilization but also after it develops into a fruit. Thus knowledge about the different types of ovaries found in different plant families is important.
