Single-Celled Organisms
CONCEPTUALExplain how unicellular organisms such as bacteria and Amoeba carry out all the functions of life within a single cell
Mastery Evidence
- Names examples of unicellular organisms
- Lists the seven life processes (MRS NERG) and explains how a single cell performs each one
- Contrasts how unicellular organisms meet their needs compared to multicellular organisms
Assessment Prompt
“If [child] learned that bacteria are made of just one cell, could they explain how that single cell still manages to feed, grow, and reproduce — doing everything a whole body does?”
