Photosynthesis

QuestionAnswer
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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
