Vocabulary

QuestionAnswer
ATP Compound used by cells to store and release energy.
Photosynthesis Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon and water into oxygen.
Pigment Light absorbing molecules used by plants to gather the sun's energy.
Chlorophyll Principle pigment of plants and other photosynthetic organisms.
Thylakoid Sac-like photosynthetic membranes found in chloroplast.
Stroma Fluid portion of the chloroplast ; outside of the thylakoid
NADP+ Carrier molecule that transfers high-energy electrons from chlorophyll to other molecules.
Light-dependent reactions Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH
Light-independent reactions Set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle.
Photosystem Cluster of chlorophyll and proteins found in thylakoids.
Electron Transport Chain Series of electipn carrier proteins that shuttle high-energy elections during ATP- generating reactions.
ATP Synthase Cluster of proteins that span the thylakoid membrane and allow hydrogen ions (H+) to pass through it
Calvin Cycle The light-independant reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar.

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.
