What kind of structure does the fertilized egg develop into?

The fertilized egg develops into the embryonic structure of the seed.

Ovary develops into fruit, ovule develops into seed, fertilized egg develops into embryo, and embryo is the main structure of seed. Analysis: After a flower is pollinated and fertilized, the calyx will wither or remain, the corolla and stamen will wither, the stigma and style will wither, and only the ovary of the pistil will continue to develop and finally bear fruit.

The fertilized egg develops into embryo, the fertilized polar nucleus develops into endosperm, and the integument develops into seed coat. The ovule includes integument, egg cell and polar nucleus, and the integument develops into seed coat. There are two sperm in the pollen tube of green flowering plants, one of which fuses with the egg cell near the micropyle to form a fertilized egg, and the other fuses with the two polar nuclei in the ovule to form a fertilized polar nucleus, which is a unique double fertilization of green flowering plants.

After the flowers of green flowering plants mature, the pollen falls on the pistil stigma. Under the action of mucus on the stigma, pollen begins to germinate and form pollen tubes, which pass through the stigma and style and reach the ovary. In the process of pollen tube germination, the reproductive nucleus in pollen tube undergoes mitosis to form two sperm. After the pollen tube enters the ovule through the micropyle, the top of the pollen tube breaks and releases two sperm.

One of them is combined with the egg cell, and the other is fused with the two polar nuclei in the center to complete the double fertilization process. After fertilization, the ovary develops and bears fruit, and the ovule develops into seeds. It can be seen that the correct order of sexual reproduction of green flowering plants is flowering → pollination → fertilization → fruiting.
