Unit 3: Cell Structure & Organelle

Question 1

What are the three main things to Cell Theory?

Answer 1

1. All living things are made of cells
2. Cells are the basic unit of life
3. Cells come from the reproduction of existing
   cells

Question 2

What is the difference between Eukaryote and Prokaryote cells?

Answer 2

Eukaryotes: Have cells that have a nucleus and membrane-bound organelles
Prokaryotes: cells have no nucleus/organelles and are very simple
