2, bud propagation, bud propagation is also called bud, which is a kind of propagation method in which the mother gives birth to buds in a certain part.
3. Spore reproduction (including only asexual spores). Some organisms, when their bodies grow up, can produce a kind of cell, which can directly form a new individual without two two combination. This cell is called spore, and this reproduction is called spore reproduction.
4, vegetative reproduction, by the vegetative organs of plants (roots, leaves, stems) to produce a new way of individual reproduction, called vegetative reproduction.
5. Tissue culture shows that plant cells are totipotent. According to this theory, plant propagation can be completed by using plant tissue culture technology.
6. Cloning is a group of cells or individuals with the same genetic structure formed by asexual reproduction from precursors.
Extended data
Methods of asexual reproduction: grafting, cutting, layering and cloning; Most single-celled organisms reproduce by division, and protozoa can also reproduce sexually.
The "bud" in "bud grafting propagation" refers to the bud body growing on the mother body, not the structure of the real bud on higher plants. For example, potatoes are propagated by buds or tubers, which are vegetative rather than budding. In essence, the "bud" is the same as the mother, but the bud is smaller.
Spores in asexual reproduction are asexual spores (germ cells) with the same number of chromosomes or DNA as somatic cells. Therefore, asexual spores can only be produced by mitosis or amitosis, but not by meiosis.
