Eggs. vs. Cells

Both eggs and cells . . .

- have a membrane
- have water inside
- can have diffusion/osmosis act on them
- will have their masses/volumes changed by solutions

Only eggs . . .

- are easily visible
- are not alive
- cannot maintain homeostasis
- cannot respond to stress from solutions (the environment)
- are a model for what could happen to cells
- are permeable to sugar and salt (they can diffuse in)

Only cells . . .

- are microscopic
- are alive
- can maintain homeostasis
- can respond to stress from solutions
- are not permeable to sugar and salt (they cannot easily diffuse in)
- are alive
