Question | Answer |
Photo equals? | light |
Synthesis equals? | put together |
Where does photosynthesis occur? | in green plants, algae and some bacteria |
It is a series of complex chemical reactions where .......... energy is transformed into ........... energy? | light energy is transformed into chemical energy |
These organisms absorb the ......... and use it to convert ......... and .......... ........ into ........, ......... and ........... | Light and use it to convert water and carbon dioxide into glucose, oxygen and water. |
What are the 2 stages of photosynthesis? | The light dependent stage and the light independent stage. |
The light dependent reactions of photosynthesis occur and what does it require ? | Occur in the grana of chloroplasts and requires input from water and light energy. |
What are grana? | Stacks of membranes which contain chlorophyll |
.......... energy is .......... by ............ and this ....... energy is converted into .......... energy. | Sunlight energy is trapped by chlorophyll and this light energy is converted into chemical energy. |
............ absorbed from the ........ is used in these .............., ...... is produced and ......... is a .......... product. The ......... | Water absorbed from the ground is used in these reactions, ATP is produced and oxygen is a waste product. The energy is used in the next stage. |
Where does the synthesis part of photosynthesis occur and what does it involve. | Occurs in the stroma and involves the formation of sugar molecules from carbon dioxide. |
Does this process require light? | No |
What is stroma? | The liquid interior of the chloroplasts |
Energy from the ........ ............. stage is used in the ......... of ............... | Energy from the light dependent stage is used in the cycle of reactions. |
What happens in the cycle of reactions? | Carbon dioxide is progressively reduced to sugar. |
What is sugar? | A product and also a output. |
Where are enzymes located in photosynthesis? | In both the grama and the stroma. Speed up the process. |
What organelle do the light dependent reactions occur in? | Chloroplast |
What organelle does the light independent calvin cycle occur in? | Chloroplast |
Location of light dependent reactions? | Grama of chloroplasts |
Location of the light independent calvin cycle | Stroma of chloroplasts |
Inputs of light dependent reactions? | Radient energy (sunlight) and Water |
Inputs of light independent calvin cycle? | Carbon Dioxide |
Outputs of light independent reactions? | Oxygen (waste product) |
Outputs of light independent calvin cycle? | Sugar (product) |
Why are water and energy not included as outputs? | Because they are recycled. |
