| contribution of Jean van Helmont | growing plants material comes from water |
| contribution of Joseph Priestly | plants release oxygen |
| contribution of Jan Ingenhousz | suggested light was important in photosynthesis |
| definiton of photosynthesis | putting together with the aid of light |
| equation for photosynthesis | 6CO(2) + 6H(2)O + sun/chlorophy --> C6H(12)O(6) + 6O(2)l |
| reactants for photosynthesis | carbon dioxide (CO(2) and water (H(2)O) |
| end products of photosynthesis | glucose (C(6)H(12)O(6) and oxygen (O(2)) |
| source of enegry for photosynthesis | sun |
| enzymes for photosynthesis | chlorophyll and accessory pigments (helping) |
| does photosynthesis relase or trap energy | trap energy |
| where is energy trapped? | in glucose |
| group of organisms where photosynthesis occurs | plants (autotrophs) |
| where chlorphyll is found in the plant cell | grana or chloroplasts |
| why is chlorophyll important in photosynthesis | it traps sun's energy |
| what color are accessory/helping pigments? | yellow/orange |
| why are pigments important in photosynthesis? | they absorb light from the spectrum making more of the sun's energy |
| 2 phases of photosynthesis | Light & Dark |
| What does Light Dependent Reaction require? | sunlight |
| where does Light dependent Reation occur? | grana of chloroplasts |
| source of energy for Light Dependent Reaction | sun |
| What happens during Light Dependent Reaction? | H(2)O is split and oxygen is released in the air |
| What's another name for Dark Independent Reaction | Calvin Cycle |
| where does Dark Independent Reaction occur | in stoma of chloroplast |
| this reaction occurs during Dark Independent Reaction | C(6)H(12)O(6) (Glucose) is made |
| 3 things that effect the rate of photosynthesis | temperature, amounts of CO(2) and H(2)O, amount of light |
| when does photosynthesis occur | during the day (need sunlight) |
