| the taking in of large particles or even small organisms | phagocytosis |
| the idea that all cells arise from pre-exiting cells was first stated by | Virchow |
| the work of Schleiden and Schwann can be summarized by saying that | plants and animals are made of cells |
| one of the three basic structures common to almost all cells is the | nucleus |
| if a concentrated salt solution is on one side of a membrane and a dilute salt solution if on the other side water molucules will tend to pass through the membrane | from the dilute to the concentrated solution |
| cell specialization means that cells in an organism are uniquely suited to | perform a specific function |
| the removal of water from a cell by a contractile vacuole (helper) is an example of | faciliated diffusion |
| chloroplasts are only found in ______ cells | plant |
| list the levels of organization in a multicellular organism from smallest to the largest | cell, tissue, organ, organ system |
| if a cell with a low water concentration is placed in pure water, what will happen to the cell? | The cell will full with water till it has an equilibrium |
| list two structural differences between plant and animal cells | plants have a cell wall and chloroplasts |
| list two organelles of movement in a cell | cilia & flagella |

| each of the following is a type of tissue except (muscle, fat, stomach, and blood) | stomach |
| the cell organelle that packages and distribute molecules in the cell is the | golgi body |
| water from solutions of different concentrations moves acros a membrane as the result of | active transport |
| in the cell, proteins are made by the | ribosomes |
| which part of the cell is most directly involbed in maintaing the cell's homeostasis | cell membrane |
| the process by which molecules of a substance flow from an area of lower concentration to an area of higher concentration by using energy is.. | active transport |
| unlike smooth ER, rough ER has: | ribosomes |
| the passage of water molecules though a selectively permeable membrane is called: | osmosis |
| the third level of organization in a mammal consists of: | organs |
| small, membrane-bordered structures that use enzymes to digest certain materials in cells are called: | lysosomes |
| the passage of substances across a membrane without using energy is: | passive transport |
