| Number | Word | OWN definition (not copied) | Picture/example/analogy (you cannot use the same picture more than twice) |
| 41 | Plasma membrane | The barrier of cells that is made of a phospholipid bilayer. | |
| 42 | Fluid mosaic model | The idea that cell membranes can have different molecules embedded in them such as protein channels and cholesterol. | |
| 43 | Phospholipids | biological macromolecules with hydrophilic heads and two hydrophobic tails. | |
| 44 | Selective permeability | The idea that only certain molecules are able to pass through a cell membrane due to certain properties | |
| 45 | Concentration gradient | The difference in concentration of a particular solute in solution | |
| 46 | Passive transport | Molecules passing through a cell membrane with the concentration gradient (high to low) | |
| 47 | Diffusion | Molecules passing through a membrane without a channel | |
| 48 | Facilitated diffusion | Molecules passing through a membrane with a protein channel assisting | |
| 49 | Active Transport | Molecules passing through a cell membrane against the concentration gradient; requires energy | |
| 50 | Endo/exocytosis | The process of larger molecules entering or exiting a cell by some membrane forming a vesicle around the molecule | |
| 51 | Osmosis | Water passing through a cell membrane (or other barrier) | |
| 52 | Hypertonic | Relative term describing more solute in solution | |
| 53 | Hypotonic | Relative term describing less solute in solution | |
| 54 | Isotonic | Relative term describing equal solute in solution | |
| 55 | Water potential | Value that describes the tendency of water two move between two solutions, water will move from higher water potential to lower water potential. | |
| 56 | Solute potential / pressure potential | Two terms that sum to form water potential, higher solute = lower solute potential, more pressure = higher pressure potential | |
| 57 | Surface area to volume ratio | The surface are of a cell divided by it's volume | |
| 58 | Organelle | A part of a cell that can act mostly independently and performs a specific task. | |
| 59 | Ribosomes | Parts of a cell that help to form the primary structure of new proteins. | |
| 60 | Cytosol | The solution inside a cell that all organelles and parts reside in | |
| 61 | Prokaryote | A more primitive type of cell with no nucleus, cell wall and no membrane-bound organelles | |
| 62 | Eukaryote | A more complex type of cell that makes up plants and animals that includes a nucleus and membrane-bound organelles | |
| 63 | Membrane-bound organelle | A complex part of a cell that includes a membrane separating it from the rest of the cell | |
| 64 | Nucleus | A organelle in a cell that contains the DNA and genetic material for a cell | |
| 65 | Endoplasmic Reticulum (rough & smooth) | Organelles that help to form both proteins and lipids respectively | |
| 66 | Golgi | Organelle that helps to finish and package proteins for transport within or outside of the cell | |
| 67 | Lysosomes | Organelles containing highly basic solution that helps to clean up the cell and assists in apoptosis. | |
| 68 | Vacuole | Containers in cells that contain water or other materials for the cell | |
| 69 | Mitochondria | The powerhouse of the cell! | |
| 70 | Chloroplasts | Organelles in plants that can take in sunlight and convert it to energy | |
| 71 | Cytoskeleton | Part of a cell that helps to resist mechanical deformations | |
| 72 | Cell wall | More rigid barrier in both plant cells and prokaryotes. | |
