The study of cells
What is cytology
A structure inside the cell that performs special functions in the cell
What is an organelle
A "steady state"
What is homeostasis
Double membrane that completely surrounds the nucleus
What is a Nuclear Envelope
Contains all the structures and materials inside the cell membrane
What is the cytoplasm
Living things are made up of both cells and cell ________________
What are cell secretions
Give an example of a multicellular organism
What is answers may vary
Why is a mouse smaller than a human if our cells are about the same size?
What is a difference in the number of cells
Shorter and usually cover the entire cell. Can function in moving the cell, or in moving the environment
What are Cillia
Large membrane bound organelles that contain food, water, waste, or other materials
What are Vacuoles
Describe what happens to a cell in a isotonic solution
What is materials would flow in and out of the cell evenly
First person to observe and name cells
Who is Robert Hooke
If you could pick one team to win the world series every year, that team would be
Obviously the Cubs Chicago
Small, irregularly shaped membrane bound organelles filled with digestive enzymes

What is one bring things inside the cell, and the other takes things out of the cell
Point where an organism cannot survive
What is known as the limit of tolerance
Name 2 of the three basic principles of cell theory
What are
The cells is the basic unit of all living things
Cells perform all the functions of living things
New cells come from the reproduction of existing cells
Secrete steroids and lipids and can help break down toxic substances
What is the smooth ER
Contains large concentrations of RNA and is the site in the nucleus where ribosomes are partially assembled.
What is the nucleolus
Type of transportation that uses cell energy
What is active transport
Main limiting factors of cell size
What are both the DNA as well as the surface area to volume ratio. Less surface area and more volume means the cell eventually cannot receive enough nutrient's to maintain the cell
The main differences between eukaryotic and prokaryotic cells
What is eukaryotic cell have a membrane bound nucleus and also have some membrane bound organelles
Structures that contain pigments
What are Chromoplast
An addition to a cell wall
What is a capsule
