One , the natural reproduction process of humans
1. Male testicles produce sperm: female ovaries produce eggs.
3. The sperm enters the ovary and combines with the egg to form a fertilized egg.
4. The fertilized egg moves to the uterus and divides continuously to form a blastocyst.
5. The cells in the blastocyst continue to differentiate to form an embryo.
6. The embryo develops in the uterus to give birth to offspring.
2. What is the process of plant fertilization
Pollen on The pistil then sprouts pollen tubes from the stigma and directly reaches the ovary. Then two sperms in the pollen enter the ovary, one combines with the egg cell, and the other combines with the vegetative cell produced when the egg cell is produced to form the fertilization polar nucleus. The fertilization polar nucleus will develop into the endosperm, which provides nutrients for the development of the embryo. It is worth mentioning that monocotyledonous plants retain the endosperm when their seeds mature, while dicotyledonous plant seeds are slowly absorbed during development, so the nutrient reserve of mature dicotyledonous seeds is the cotyledon
The article ends here. If the process of combining sperm and eggs and the process of plant fertilization shared this time has solved your problem, then we are sincerely happy!
