Answer:
Structures that perform different activities
Step-by-step explanation:
The different pieces of food represent cell organelles. Cell organelles can be thought of as the cell's mini "organs", each specialized to carry out different functions inside.
For example the nucleus stores our genetic information, ribosomes synthesise proteins, and Golgi apparatus modifies and transports proteins.
This is similar to how our heart, lungs, stomach, and brain perform different roles in the body.
