Reproduction, asexual defined

Protozoa are unicellular organisms with a well-defined cell nucleus. Some species are capable of sexual reproduction, while others reproduce asexually. In addition to their vegetative (usually motile) forms, most protozoa also develop cysts as a permanent state under unfavourable external conditions. They move with the aid of flagella or cilia, by amoeboid locomotion, or in a winding, gliding manner.
