Stack #4632724

QuestionAnswer
ATP (Adenosine Triphosphate) The main energy molecule used by cells.
ADP (Adenosine Diphosphate) A low‑energy molecule that becomes ATP when a phosphate is added.
Photosynthesis The process plants use to convert sunlight into chemical energy stored in sugars.
Pigment A molecule that absorbs light.
Chlorophyll The main pigment in plants that absorbs light for photosynthesis.
Chloroplast The organelle where photosynthesis occurs.
Thylakoid Flattened sacs inside chloroplasts where light‑dependent reactions occur.
Granum (Grana) Stacks of thylakoids.
Stroma The fluid surrounding the thylakoids where the Calvin cycle occurs.
NADP+ An electron carrier that becomes NADPH when it picks up electrons.
NADPH A high‑energy electron carrier used in photosynthesis.
Why do organisms need energy? To grow, move, reproduce, and carry out cell processes.
What is ATP? A molecule that stores and releases energy for the cell.
How does ATP release energy? By breaking off a phosphate group.
What is photosynthesis? A process that converts light energy into chemical energy stored in glucose.
What is the photosynthesis equation? 6CO2+6H2O+light energy→C6H12O6+6O2
Where does photosynthesis occur? In the chloroplast.
Where do light‑dependent reactions occur? In the thylakoids.
Where does the Calvin cycle occur? In the stroma.
Why are pigments important? They absorb light energy.
Why do plants appear green? Chlorophyll reflects green light.
What do light‑dependent reactions produce? ATP, NADPH, and oxygen.
What does the Calvin cycle produce? Glucose.
Why do plants appear green? Chlorophyll reflects green wavelengths of light.
What are the products of the light‑dependent reactions? ATP, NADPH, and oxygen.
What does the Calvin cycle produce? Glucose (sugars).

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.

To see how well you know the information, try the Quiz or Test activity.
