Cell Eating – Endocytosis (phagocytosis)
Consider these following questions before we complete the activity.
Cells need energy but how can they eat?
How do large particles, those too large to diffuse (break down), get into cells?
Do cells have mouths?
Which cell organelle could function as a mouth?
What would happen to food if it did get into a cell, what organelles would deal with it?
Activity
Your group should have:




1 plastic shopping bag
1 pair of scissors

Four pieces of candy
The Problem:



The candy must enter through a solid part of the bag.
The inside of the bag may not be directly open to the external environment.
The candies entering the bag must remain clustered together.
You may work with your hand in the bag to simulate the organelles inside the
cell.
 The candy may only be eaten if it enters the bag “cell” under all of the above
conditions.

Endocytosis - Activity Reflection
1. How do cells eat their food? Include a diagram with your
explanation.
2. What happens to the food when it enters the cell?
3. What do you feel you learned from this activity?
