QuestionAnswer
ATP synthetase an enzyme complex in the inner membrane of a mitochondrion and the thylakoid membrane of a chloroplast that catalyzes the formation of ATP
bundle sheath a tightly packed layer of cells that surrounds a vascular bundle in the leaves of C4 plants, plants such as crabgrass and corn in which carbon dioxide is fixed twice
Calvin cycle the cycle that incorporates carbon dioxide in sugars during photosynthesis; uses chemical energy previously converted from light energy
CAM crassulacean-acid metabolism; an adaptation for photosynthesis in arid conditions in which carbon dioxide entering open stomates at night is converted into organic acids that release carbon dioxide during the day when the stomates are closed
chemoautotroph an organism that derives energy from the oxidation of inorganic compounds, such as hydrogen sulfide (H2S)
chemoheterotroph an organism that must consume organic compounds for energy and carbon
chlorophyll the green pigments of plants and many microorganisms; converts light energy (via changes involving electrons) to chemical energy that is used in biological reactions
chloroplast an organelle found in plants and photosynthetic protists; the site of photosynthesis
light reactions the energy-capturing reactions in photosynthesis
limiting factor an environmental factor such as food, temperature, water, or sunlight that restricts growth, metabolism, or population size
NADP nicotinamide adenine dinucleotide phosphate; a hydrogen carrier in photosynthesis
photoheterotroph an organism that derives energy from light but requires a source of organic compounds
photoinhibition damage to the light-gathering process in photosynthesis; occurs when a chloroplast has absorbed too much light energy
photorespiration a metabolic pathway in plants that consumes oxygen, produces carbon dioxide, generates no ATP, and reduces photosynthesis
pigment any coloring matter or substance
rate the amount of change over a period of time

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.
