| Question | Answer |
| Where does photosynthesis take place? | In the organelle chloroplast |
| What pigment does photosynthesis occur in? | chlorophyll |
| What gas is needed for photosynthesis? | Carbon Dioxide [CO2] |
| Where do the gases come in? | The stomata |
| What is the chemical equation for photosynthesis? | 6CO2 + 6H20 = 6H20 + C6H1206 |
| What energy source is needed for the first part of the light dependent stage? | Photons |
| What shape is the chlorophyll? | The chlorophyll is in a cone shape to receive more photons |
| How does the energy from photons get passed down the chlorophyll molecule? | The energy from the photons are passed down randomly from pigment molecule to pigment molecule |
| Where do the energized electrons go to? | Reactor centre 'Chlorophyll A' |
| What is produced if the energized electrons go back to the chlorophyll? | ATP |
| Where do energize electrons go after the reactor center? (Route 2) | They go to the acceptor molecule |
| What energy source is found at the 'Acceptor Molecule'? | NADP+ |
| What products are made at the splitting of water? | Electrons, Hydrogen ion and Oxygen |
| Where do the electrons go after the splitting of water? | Electrons join the NADP+ to create NADP- |
| What is attracted to NADP-? | Hydrogen+ is attracted to NADP- |
| What energy product is produced from this attraction? | NADPH+ |
| What is the name of the second stage in photosynthesis? | The Light-Independent Stage |
| How is Carbon dioxide converted into carbohydrates, eg. glucose (C6H12O6)? | Carbon dioxide is converted into glucose by using the Hydrogen ion from NADPH |
| How is ATP used in this conversion? | ATP is used as an energy source |
| What happens to ATP after being used? | ATP splits into ADP + P and later combines into ATP |
| What happens to glucose (C6H12O6)? | Glucose is turned into starch to be stored for later use |
| What happens to Oxygen after the splitting of water? | Oxygen is released as a waste gas from the stomata |
