What type of membrane is a cell membrane? | semi-permeable |
What do we call the normal rigid state of fullness in a cell or blood vessel? | turgor |
What do we call the diffusion of water? | osmosis |
What type of transport requires energy to move from areas of low concentration to areas of high concentration? | active transport |
What do we call the random movement of substances from an area of higher concentration to an area of lower concentration? | diffusion |
What type of transport is it when molecules are so large they must pass through a cell membrane using special proteins called transport protiens? | facilitated diffusion |
What type of active transport is it when a cell takes in substances by surrounding it with the cell membrane? | endocytosis |
What do we call it when substances cross the cell membrane. but does not use the cell's energy? | passive transport |
What type of active transport is it when a cell releases its contents from an area of low concentration to an area of high concentration? | exocytosis |
What represents the energy made in respiration? | ATP |
What is a series of chemical reactions that take place in a chloroplast of a cell to produce food? | photosynthesis |
Where in a cell does glycolysis occur? | cytoplasm |
In what part of a cell does aerobic cellular respiration take place? | mitochondria |
What does the part of cellular respiration that happens in the mitochondria require? | oxygen |
What does C6H12O6 stand for? | Glucose |
What chemical equation is C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP? | aerobic cellular respiration |
Water + Carbon Dioxide + Sunlight --> Glucose + Oxygen is the word equation for what process? | photosynthesis |
In what part of the cell does photosynthesis take place? | chloroplast |

What do humans use to gain energy when oxygen levels are low? | lactic acid fermentaion |
In what organism or organisms does respiration occur? | plant and animal |
What is the word equation for aerobic cellular respiration? | glucose + oxygen --> water + carbon dioxide + ATP |
What are the two types of fermentation? | alcohol and lactic acid |
true of false: oxygen and sugar are used in a process that povides energy to cells; water and carbon dioxide are its waste products | true |
true or false: Water and sugar are used in the process that provides energy to cells; oxygen and carbon dioxide are its waste product | false |
The transfer of nitrogen from the atmosphere to plants and animals is which cycle? | nitrogen cycle |
Would osmosis occur across a permeable membrane that separates solutions of the same concentration? | not likely |
Would osmosis occur across a permeable membrane that separates solutions of different concentrations? | yes |
What are the types of active transport? | endocytosis and exocytosis |
Which way do molecules flow during active transport? | low to high |
Which way do molecules flow during passive transport? | high to low |

When molecules are spread evenly it is called? | equilibrium |
Be able to identify illustrations of active transport, diffusion, osmosis and equilibrium | |
How are the photosynthesis and respiration related to the carbon cycle? | photosynthesis uses the carbon in carbon dioxide to make glucose, while respiration breaks down glucose containing carbon and gives off carbon dioxide |
