| The movement of water molecules across a cell membrane is called ___. | osmosis |
| In a salt and water solution, the salt is known as the ___. | solute |
| If a cell membrane allows glucose to pass through it, then the cell membrane is said to be ____ to glucose. | permeable, 
|
| The movement of particles across a cell membrane from areas of high concentration to areas of low concentration is known as ____. | diffusion,  |
| The cell membrane is said to be _______ permeable to substances because it lets some pass through but not others. | selectively |
| The composition of nearly all cell membranes is a double-layered sheet called a __________ | lipid bilayer |
| Larger molecules and charged particles usually pass through _____ to get into cells. | channel protein |
| Cells will shrink if placed into a _____ solution. | hypertonic |
| When energy is needed to force molecules across a cell membrane, _______ is taking place. | active transport,  |
| Cells will grow bigger if placed in a ____ solution. | hypotonic |
| A solution that has the same concentration of solutes as the interior of a cell is known to be ____. | isotonic |
| Active transport requires _____. | energy |
| If a substance is diffusing across a cell membrane, it is going from an area of ____ concentration to an area of ___ concentration. | high, low |
| When water moves into plant cell, the ______ gets bigger and the plant ___. | central vacuole, gets turgid (stiff) |
The process pictured below is called ____.,  | exocytosis, ,
|
The process pictured below is called ____.,  | endocytosis, ,
|
| In comparing two solutions, the one with the greater solute concentration is called the _____ solution. | hypertonic |
| _______ transport involves the diffusion of a substance across a biological membrane. | Passive |
| Passive transport involves the ______ of a substance across a biological membrane. | diffusion |
| _______ involves the movement of a substance across a biological membrane against its concentration or electrochemical gradient with the help of energy input and specific transport proteins. | Active transport, |
| A property of biological membranes that allows some substances to cross more easily than others is called _____. | selective permeability |
| In comparing two solutions, the one with the lower solute concentration is called the _____ solution. | hypotonic |
| _______ diffusion is the process of large molecules moving from high concentration to low concentration through a protein channel. | Facilitated,  |
| The picture below is showing _____., | active transport, |
| Which process is shown below?, | Simple diffusion, |
| Which process is shown below?, | facilitated diffusion (It's diffusion because the particles are travelling down the concentration gradient. It's facilitated because a channel protein is helping), |
What type of solution was the cell on the left exposed to?,  | hypotonic, |
| What type of solution was the cell on the middle exposed to?, | isotonic, |
| What type of solution was the cell on the right exposed to?, | hypertonic, |
