What is an independent variable?
300
Name the three parts of the cell theory.
1. Cells come from pre-existing cells.
2. All living things are made of cells.
3. Cells are the basic units of life.

You are investigating a new single-celled organism and you see that it does not have a nucleus. Would this organism be a prokaryote or eukaryote?
Prokaryote
300
Function of Endoplasmic reticulum
What is the organelle that creates ribosomes?
300
The phase of mitosis in which the cell begins to divide and chromosomes pair up.
What is prophase?
400
A scientific tool used to magnify and see small objects, such as cells.
What is a microscope?

Define homeostasis.
What is the ability to maintain a stable internal environment?
400
The key difference between prokaryotes and eukaryotes
What is prokaryotes do not have nuclei and eukaryotes do have nuclei?
400
Organelle with the nickname "protein factory"
What is a ribosome?
400
A solution in which the concentration of solutes outside the cell is more than the concentration of solutes inside the cell. Materials will move out of the cell.
What is a hypertonic solution?
500
Define control variable
What is a variable that an experimenter uses to focus on the results of changing the independent variable. Keeps the experiment constant/ fair?

1. Living things need energy to carry out life's processes.
2. Living things respond to their environment.
3. Living things grow and reproduce.
4. Living things are composed of cells.
5. Living things maintain a stable internal environment.
500
Name at least 4 differences between animal cells and plant cells.
1. Plant cells have a cell wall.
2. Plant cells have chloroplasts.
3. Plant cells have large vacuoles.
4. Animal cells have small vacuoles.
5. Animal cells have centrioles.

Function of Golgi apparatus.
What is the organelle that sorts, packages and transports proteins throughout the cell?
500
The phase of mitosis in which the spindle fibers pull the chromosomes apart and towards the sides of the cell?
