question
asexual reproduction
answer
process by which a single parent reproduces by itself plants reproduce by using asexual reproduction.

a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size binary fission seems weird to me.
question
budding
answer
reproduction of some unicellular organisms (such as yeasts) by growth and specialization followed by the separation by constriction of a part of the parent budding is a very interesting way to reproduce.
