| accessory pigments | a yellow, orange, or red pigment found in plant cells that absorb light for photosynthesis |
| visible spectrum | light we can see |
| red, orange, yellow, green, blue, and (indigo) violet | colors of the visible spectrum |
| prism | object that breaks white light into its individual colors |
| refract | to break white light into its different colors |
| reflect | when light is bounced back, reflects the color you see |
| absorb | when light is taken in and the object heated up |
| transmit | when light passes through an object |
| chloroplast | organelle in plant cells where photosynthesis takes place |
| chlorophyll | green pigment in chloroplasts that absorbs sun's energy for photosynthesis |
| light energy | needed for photosynthesis, comes mainly from the sun |
| photosynthesis raw materials | CO2, H2O, (minerals dissolved in the water) |
| products of photosynthesis | C6H12O6 (glucose), and oxygen released |
| chemical energy | type of energy stored in the bonds of the sugar and starch molecules made during photosynthesis |
| photosynthesis formula | 6 CO2 + 6 H2O --> C6H12O6 + 6 O2 |
| balanced equation | matter on both sides are equal |
| Law of Conservation of Matter | matter cannot be created or destroyed, only change forms |
| Law of Conservation of Energy | energy cannot be created or destroyed, but changes form as it passes through the ecosystem |
| autotroph | organism that can make its own food for energy |
| heterotroph | organism that depends on other organisms for food energy |
| number of molecules | the number written in front of the formula |
| number of atoms of an element | the subscript number written right after the element symbol |
| number of elements | each capital letter is a new element in a formula |
| 2H3O has _____ molecules? | 2 |
| 2H3O has ___ atoms of H? | 6 |
| NaCaO3 has how many elements? | 3 |
| pigment | absorbs some light and reflects the rest, determines the color of things |
| green | color of chlorophyll due to green light being reflected |
