NEET BIOLOGY

Detailed explanation-1: -After fertilisation the fertilised egg develops into an embryo and the primary endosperm nucleus into the endosperm. The ovule is converted into seed and ovary into fruit.

Detailed explanation-2: -Fertilized ovules ripen into seeds. The seeds are covered by fruits. A fruit is technically a ripened ovary. Gymnosperms contain ovules but they lack ovary, therefore, seeds are formed but fruits are not formed.

Detailed explanation-3: -After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.

Detailed explanation-4: -Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.

Detailed explanation-5: -Once pollen gets to the ovary within the flower, the ovary develops into a fruit. The ovules inside the ovary develop into seeds inside of this fruit.
