What organelle controls the functions of the entire cell?
The nucleus! It is the brain of the cell.

What do vacuoles do for cells?
Vacuoles are for storage. Vacuoles hold water in plant cells and both water and food in animal cells.
100
What type of cells have vacuoles?
Both plant and animal cells have vacuoles.

What are the type types of microscopes we talked about?
Electron and light microscopes.
200
What surrounds the outside of a plant cell?
The cell wall - a rigid non living layer that protects the plant cell.
200
What does the cell membrane do?
Surrounds both plant, animal and bacteria cells. Lets some things through and keeps some things out.
200
Which will have more chloroplasts - a carrot or lettuce?
Lettuce will have more chloroplasts because carrots grow underground without sunlight. Only the top part of carrots will have chloroplast but all of the lettuce cells will have many chloroplasts.

Is it impossible for a living thing to be only a single cell?
No! There are many single celled organisms.
300
What organelle stores DNA and Chromosomes?
The nucleus!
300
What does DNA do for the cell?
DNA stores genetic information.

Who are the three men responsible for cell theory?
Schwann, Schleiden, Virchow

Which organelle supplies the cell with energy?
The mitochondria creates energy for cells. Muscle cells would have more than skins cells because of the work they do.
400
What does the endoplasmic reticulum (ER) do for the cell?
The ER creates and packages proteins.
400
What type of cell has only a cell membrane, DNA and cytoplasm?
A bacteria cell.

What does this theory tell us about how cells are created?
All cells come from other cells.
500
What organelle converts light energy into sugars?
Chloroplasts help plant cells get energy from the sun.

What do lysosomes do?
Lysosomes break down waste in animal cells.
500
What type of cell has lysosomes?
Animal cells are the only kinds that have lysosomes.

List all three parts of cell theory.
1. All cells come from other cells
2. All living things are composed of one or more cells
3. Cells are the basic unit and structure of life
