200
Organelle responsible for chemical and water storage
What is a vacuole
200
These control movements during cell replication inside the nucleus
What is centrioles
300
A subject identical to the experimental subjects, but it is not exposed to the independent variable.
What is a control
300
The process by which molecules move passively into and out of cells
What is diffusion
300
The abiltiy of a cell to maintain a precise balance of temperature, water content, sodium and potassium
What is homeostasis
300
the process of conversion of light energy into chemical energy (not an organelle)
What is photosynthesis
300
A whiplike structure that helps a simple cell to move
What is flagella
400
A variable that is responding to another variable in an experiment
What is dependent variable
400
Diffusion is a form of transport, requiring no energy
What is passive transport
400
organelle that houses DNA
What is the nucleus
400
Organelle that converts sugar into chemical energy (ATP)

400
organelle that synthesizes fats and lipids
What is smooth endoplasmic reticulum (SER)
500
A variable that is the cause of an effect in another variable
What is independent variable
500
process by which water molecules diffuse through the plasma membrane
