Biological reproduction modes are divided into sexual reproduction and asexual reproduction. Sexual germ cells produced by parents become fertilized eggs through the combination of bisexual germ cells (such as sperm and egg cells), and then the fertilized eggs develop into a new individual reproductive model, which is called sexual reproduction; Such as sunflower, corn and peach trees, they reproduce their offspring through seeds, which is sexual reproduction.

Asexual reproduction refers to the reproductive mode in which new individuals are directly produced by the mother without the combination of bisexual reproductive cells. Green flowering plants use the roots, stems and leaves of vegetative organs to reproduce new individuals, which is called vegetative reproduction. Nutritional reproduction is conducive to maintaining the excellent characteristics of the female parent and accelerating the reproduction speed. Vegetative reproduction is asexual and there are no hermaphroditic germ cells. Asexual propagation includes grafting, cutting, tissue culture, layering, cloning, fission propagation, budding propagation and so on.

So, the answer is: sexual reproduction; Asexual reproduction
