What organisms use
Asexual Reproduction?
 BACTERIA
 Unicellular (single
celled)
 Do not contain a true
nucleus
 Examples include:
cholera, syphilis,
anthrax and leprosy
What organisms use

 PROTISTS
 Unicellular
 DNA is contained in

(example: plankton in

reproduce asexually aside from body cells
 2) Invertebrates (do not have backbones)
 Examples include: sponges, jellyfish, worms
and insects
 Reproduce asexually to form one or more
identical offspring from a single parent.
