| carbohydrates | energy-rich organic compounds made of the elements carbon, hydrogen, oxygen |
| lipids | make and store energy for a cell |
| proteins | build new cell structures |
| amino acids | protein molecules are made of smaller molecules |
| enzyme | type of protein the speeds up chemical reaction in living thing |
| nucleic acids | long organic molecules made of carbon, oxygen, hydrogen |
| selectively permeable | SOME substances can pass through the membrane |
| diffusion | small molecules move from an area of high concentration to low concentration |
| osmosis | the diffusion of only water through selectively permeable membrane |
| passive transport | movement through a membrane without energy |
| active transport | movement through a membrane with energy |
| photosynthesis | process when cell captures light and uses it to make food |
| stomata | tiny openings on the undersides of leaves |
| heterotroph | an organism that can't make its own food |
| autotroph | an organism that makes it's own food |
| nucleic acids | provide information for the cell |
| chloroplast | chemical compound that captures light energy from the sun and uses it to produce glucose |
| fermentation | provides energy for a cell without oxygen |
| engulfing | active transport when cell membrane surrounds a particle and brings it into the cell |
| respiration | glucose is broken down while using oxygen to release energy. |
