Single cell
A tiny organism is just one cell.
How can it reproduce on its own?
What this lesson covers
The idea
Microbes and simple animals also reproduce asexually: single-celled bacteria and amoebae divide into two identical individuals, algae and Planaria regrow from small pieces, and Hydra grows buds that break off into new individuals.
Single cell
A tiny organism is just one cell.
How can it reproduce on its own?
- By splitting or budding, as one parent
- It needs two parents
- It cannot reproduce
Sort the examples
Put each organism with the way it reproduces asexually.
Splitting and budding
Single-celled organisms like amoeba and bacteria reproduce by splitting into two. Yeast and hydra reproduce by budding, where a small bud grows on the parent and separates as a new individual. All of these are asexual reproduction by a single parent.
Amoeba and bacteria split into two. Yeast and hydra bud. All are asexual (one parent).
Notes
Split: amoeba, bacteria. Bud: yeast, hydra. All asexual.
