Aim: How does the nucleus control the activities of the cell?
There are two main functions of the nucleus:
1. Contains the codes protein
2. Cell division
Task
Arrange the cell according to how you think the cell reproduces
Questions:
What do you notice about the first and last cell?
How are they the same/different ?
K-W-LWhat do you know, want to know about cell
division?
