Explanation:
Animals can actually reproduce sexually and asexually. Animals that reproduce asexually do that through fission, fragmentation, budding, etc.
Some of the animals that reproduce asexually include planarians, sea stars, annelid worms, etc.
In the fertilization process, the male sperm cell and the female egg cell come together.
Sexual reproduction involve the fertilization of egg by the sperm. In asexual, there is no fertilization. Ferns are spore-bearing plants. They reproduce via spores but their spores are not actually blackish.
