Introduction to spores: spores are germ cells that can directly or indirectly develop into new individuals after leaving their parents. It is the product of mitosis or meiosis; Most of them are haploid and a few are diploid. Spores are usually single-celled or multicellular propagules. The diversity of spores is formed due to the differences in their characters, occurrence process and structure.
There are two ways to form spores: one is the spore formed after mitosis, which is called filariasis; The other is the spore produced by meiosis, which is called meiotic spore.
