| Hint | Answer | % Correct |
|---|---|---|
| The part of a cell that separates the material outside the cell from the material inside the cell. | Cell membrane | 91%
|
| The gel-like fluid inside the cell that (1) is the medium for chemical reaction; and (2) provides a platform upon which other structures can operate within the cell. | Cytoplasm | 88%
|
| The “control center” of a cell. | Nucleus | 85%
|
| “Little organs” suspended in the cell’s gel-like fluid. Each type has a definite structure and a specific role in the function of the cell. | Organelles | 84%
|
| A cell’s genetic material. | DNA | 79%
|
| A dense region of ribonucleic acid (RNA) in the cell’s control center, and the site of ribosome formation. | Nucleolus | 71%
|
| A process that moves substances against a concentration gradient from a region of lower concentration to a region of higher concentration, requiring a carrier molecule and using energy. | Active transport | 64%
|
| The process of moving secretory vesicles from the inside to the outside of the cell. | Exocytosis | 63%
|
| A special type of cell reproduction, used only by egg and sperm cells, in which the number of chromosomes is halved. | Meiosis | 63%
|
| The diffusion of solvent or water molecules through a selectively permeable membrane. | Osmosis | 62%
|
| The type of cell reproduction used by all cells except those that give rise to the gametes. | Mitosis | 50%
|
| The general name for the process by which new cells are formed for growth, repair, and replacement in the body. | Cell division | 48%
|
| The movement of particles (solutes) in a cell from a region of higher solute concentration to a region of lower solute concentration. | Simple diffusion | 48%
|
| The formation of vesicles to transfer particles and droplets from outside to inside the cell. | Endocytosis | 46%
|
| A process that uses pressure to push substances through a membrane. | Filtration | 28%
