A seed is ripened ________

Ovary
Flower
Gynoecium
Ovule

The correct answer is: A. Ovary

An ovary is the female reproductive organ in flowering plants. It is located in the pistil, which is the female part of the flower. The ovary contains ovules, which are the female gametes. After fertilization, the ovules develop into seeds.

The other options are incorrect because:

  • A flower is the reproductive structure of an angiosperm. It is typically composed of four main parts: the sepals, petals, stamens, and pistil. The sepals and petals are the non-reproductive parts of the flower. The stamens are the male reproductive organs, and the pistil is the female reproductive organ.
  • A gynoecium is the female reproductive organ of a flower. It is composed of the stigma, style, and ovary. The stigma is the part of the gynoecium that receives pollen. The style is the tube that connects the stigma to the ovary. The ovary is the part of the gynoecium that contains the ovules.
  • An ovule is the female gamete of a flowering plant. It is located in the ovary. After fertilization, the ovule develops into a seed.
