List the two types of cells.
Eukaryotic & Prokaryotic
100
The uneven distribution of electrons makes water
Polar
100
Transport that requires no energy and materials move from an area of high concentration to low concentration
Passive Transport
100
Active transport where small pockets of liquid are taken into the cell
Pinocytosis
100
Purpose of the cell membrane
Regulates what enters and leaves the cell
200
Identify the prokaryotic and eukaryotic cell 
A= prokaryotic B= eukaryotic
200
A solution that resists a change in pH when strong acids or bases are added
Buffer
200
Three types of passive transport
Diffusion, Osmosis, Facilitated diffusion
200
Active transport where the cell bringing a molecule (particle) INTO the cytoplasm
Endocytosis
200
The phosphate head
Hydrophilic/polar

What is the cell theory?
1. all cells come from pre-existing cells 2. cells are the basic unit of structure and function of living things 3. all living things are made up of one or more cells
300
When pH is high, Hydrogen ion concentration is
Low
300
When a normal cell is placed in a hypertonic solution it
There is a net movement of water out of the cell and will shrink due to osmotic pressure.
300
The two types of endocytosis
Phagocytosis (large solid molecules) and pinocytosis (molecules dissolved in liquid)
300
Material that channels and pumps are made of
Proteins

If viewing a cell under a microscope, how would you be able to identify the cell as either a plant or animal cell.
Plant- square, cell wall, LARGE central vacuole and chloroplast
animal cell- round, small vacuoles (if any)
400
The characteristic of water molecules sticking to other surfaces
Adhesion
400
In a hypotonic solution
Water enters cell, it swells and internal pressure increases. Animal cells may break (lyse), plant cells are supported by cell walls and will not break
400
Exocytosis.
Vesicles are filled with molecules in the inside of the cell and then fuse with the plasma membrane and deposit the molecules outside the cell.
400
An animal cell with an internal concentration of 1.0% is placed in a solution with a salt concentration of 0.3%
The cell will swell and burst due to the solution being hypertonic with respect to the cell, causing a movement of water into the cell
500
Describe what is happening to the cells in the image below. Be sure to mention all organelles and concentrations involved.
cell was placed in a hypertonic solution and water is diffusing out of the cell through the process of osmosis.
500
The concentration of H+ in solution, or the measure of how acidic or basic a solution is
pH
500
Type of passive transport would be used to move the following molecules across the cell membrane: glucose, small molecules in solution, and water
glucose-facilitated diffusion, small molecules in solution-diffusion, water-osmosis
500
What type of transport is represented and why?Active transport: energy is being used and molecules are moving from low to high concentration.

Keeps membrane “fluid” by preventing fatty acid tails from sticking together
