Asexual reproduction
One individual is enough.
Going solo
A cell of Amoeba splits into two. A Hydra grows a bud. A Spirogyra thread breaks into pieces.
How many individuals does each of these need to create a new generation?

Which of these is an example of asexual reproduction?
Plasmodium divides into many daughter cells by multiple fission. How many individuals are needed?
- two individuals, a male and a female. This is sexual reproduction, which needs two individuals.
- a single individual — correct. Yes!
- two cells of a different kind. Asexual reproduction needs only one individual.
- A hen and a rooster producing chicks. Hens alone cannot produce new chicks. Both sexes are needed, so this is not asexual.
- A bull and a cow producing a calf. Bulls alone cannot produce new calves. Both sexes are needed, so this is not asexual.
- A Hydra growing a bud that detaches — correct. Yes!
- One — correct. Yes!
- Two, a male and a female. In multiple fission a single-celled organism divides by itself.
- Many, one for each daughter cell. The daughter cells are produced from one single-celled organism.
