Biology Ch. 8

TermDefinition
Adenosine Triphosphate (ATP) Compound used by cells to store and release energy
Heterotroph Organism that obtains food by consuming other living things; also called a consumer
Autotroph Organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer.
Photosynthesis Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.
Pigment Light-absorbing molecule used by plants to gather the sun's energy.
Chlorophyll Principal pigment of plants and other photosynthetic organisms
Thylakoid Sac-like photosynthetic membranes found in chloroplasts.
Stroma Fluid portion of the chloroplast; outside of the thylakoids.
NADP+ Carrier molecule that transfers high-energy electrons from chlorophyll to other molecules. (nicotinamide adenine dinucleotide phosphate)
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 thylakoid.
Electron Transport Chain Series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
ATP Synthase Cluster of proteins that span the cell membrane and allow hydrogen ions (H+) to pass through it.
Calvin Cycle Light-independent 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.
