# Cells and Systems Word Search

This puzzle reviews the big ideas from Unit B: Cells and Systems. Every living organism is built from cells, and those cells depend on processes like diffusion and osmosis to move gases and liquids across the cell membrane ([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/17320)). In humans, systems for circulation, digestion, and respiration keep the body functioning, and the body constantly reacts to internal and external stimulus ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)). Find all eight terms hidden in the grid below.

## How to play

- Search the grid horizontally, vertically, and diagonally, in both directions, to find each word from the list.
- Circle or highlight each word as you find it, then cross it off the word list so you can track your progress.
- Some words may share letters where they cross paths in the grid, so read carefully before deciding a word isn't there.

## Words to find

- CIRCULATION
- DIFFUSION
- DIGESTION
- MEMBRANE
- ORGANISM
- OSMOSIS
- RESPIRATION
- STIMULUS
