Detailed explanation-1: -In flowering plants after fertilisation, the zygote develops into the embryo, the ovules develop into the seed and the ovary develops into the fruit.

Detailed explanation-2: -The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant. The ovary develops into a fruit to protect the seed. Some flowers, such as avocados, only have one ovule in their ovary, so their fruit only has one seed.

Detailed explanation-3: -Plant Fertilization 101 Plant fertilization is the union of male and female gametes (reproductive cells) to produce a zygote (fertilized egg). So, how does fertilization occur?

Detailed explanation-4: -Fertilization occurs as one of the sperm cells fuses with the egg inside the ovule. After fertilization takes place, the ovule develops into a seed that contains a tiny, undeveloped plant. The ovary surround-ing the ovule develops into a fruit.

Detailed explanation-5: -Fertilization Process The pollen tube opens into the ovule through the micropyle and bursts into the embryo sac. Here, the male nucleus unites with the nucleus of an egg inside the ovule forming a diploid zygote, which later swells up and develops into a fruit.
