The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.
The flower is a modified shoot of the plants which acts as a reproductive structure in plants.
The flower is a characteristic feature of angiosperms which was evolved as an adaptation to survive. It encloses the gametophytic structure of the plants present on the stamens and carpels. Stamen produces male gametophyte- pollen grains and carpel produces- embryo sac which encloses egg cell.
