| Question | Answer |
|---|---|
| Which scientist contributed this part of the cell theory - "All cells come from existing cells"? | Rudolf Virchow |
| Leeuwenhoek discovered tiny creatures living in pond scum and he called them "animalcules". What do we call these creatures today? | Protists |
| Which scientist looked at cork under a microscope and noticed that it looked like it was made of little boxes or "cells"? | Robert Hooke |
| What is the smallest unit that can perform all the processes needed for life to exist? | Cells |
| Several scientists worked together to develop the cell theory. What are the three parts of the cell theory? | 1. All organisms are made of one or more cells. 2. The cell is the basic unit of all living things. 3. All cells come from existing cells. |
| Which organelle, also known as the "control center" of the cell, contains the genetic material called DNA? | Nucleus |
| What does the cytoskeleton do for the cell? | The cytoskeleton keeps the cell from collapsing and allows some cells to move. |
| How does the cell store energy produced by the mitochondria? | Energy is stored as ATP |
| What structure, found in both animal and plant cells, is a barrier that protects the cell and moves nutrients in and out? | The cell membrane |

| What are three advantages to being a multicellular organism? | 1. Larger size 2. Longer life 3. Specialization of body parts |
| What do we call an organism that is made up of "many" cells? | multicellular |
| What are the smallest, most common form of prokaryotes? | bacteria |
| What do we call "mini organs" that are surrounded by membranes and perform specific jobs within the cell? | organelles |
| What is a single-celled organism that has no nucleus or membrane-bound organelles; very simple? | prokaryotes |
