BOTANY

Detailed explanation-1: -Answer and Explanation: The ovary is the part of the flower where fertilization takes place. The ovary is part of flowering plant’s female reproductive structure known as the carpel. Typically, there is usually one large ovary for every flower, and it is usually located within the center of the flower.

Detailed explanation-2: -After fertilization in flowering plants, the sepals, petals and stamens of the flower fall off. However, the ovary remains attached to the plant.

Detailed explanation-3: -The sepals and petals are accessory parts or sterile appendages; though they protect the flower buds and attract pollinators, they are not directly involved with sexual reproduction.

Detailed explanation-4: -Flower fertilization requires both male and female gametes. If pollination does not occur it means that the male gamete is not available, hence fertilization cannot take place.
