# Cells and Systems Word Search

Every living thing, from a single amoeba to a human body, is built from cells that work together as a system. In Grade 8 Science, you study how organs and tissues carry out jobs like circulation, digestion, respiration and excretion, and how substances move into and out of cells by diffusion ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)). This puzzle reviews the vocabulary you need to describe how an organism's structure supports its function ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17319), [Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)).
