What is a Solution?
A mixture of materials with solute and solvent.
What is Osmosis?
The movement of water across the membrane.
What is exocytosis?
Molecules exiting the cell by the out folding of the membrane.
What is Isotonic?
A solution where there are equal amounts of solute and solvents on both sides of the cell.
What are the heads of a phospho lipid called?
A Hydrophilic Head
What does the breaking down in a solution?
Solvent
What is Diffusion?
The movement of molecules from an area of high concentration to low concentration.
What is endocytosis?
Molecules entering the cell by infolding the cell.
Which tonic causes the cell to expand?

Do the tails of a phospho lipid like water and what are they called?
They do not like water and known as hydrophobic tails.
What is it called when you are maintaining an internal stable environment?
Homeostasis
Facilitated and Simple

Hypertonic
What proteins allowed molecules to get inside a cell membrane?
Carrier Proteins
What proteins contain channel and carrier proteins?
Integral proteins
What is the difference between facilitated and simple diffusion?
Facilitated diffusion is larger molecules with the help of protein and simple diffusion is smaller molecules without the help of protein.
phagocytosis
What is the difference between Hypertonic and Hypotonic?
Hypertonic is more solute(salt) on the outside than on the inside, while hypotonic has more salt on the inside.
