QuestionAnswer
Autotrophs An organism that produces its own nutrients from inorganic substances or from the environment
Heterotrophs An organism that obtains organic food molecules by eating other organisms or their by products and that cannot synthesize organic compounds from inorganic materials
Photosynthesis The conversion of light energy from the sun into chemical energy in the form of organic compounds
Light reaction The first set of reactions in photosynthesis which are triggered by the absorption of light and produced NADPH and ATP to be used in the Calvin cycle
Chloroplast Organelles found in the cells of plants and algae
Thylakoid Membrane system of sacs found in chloroplasts that contain cholorophll and are the site of the light reaction in photosynthesis
Stroma The solution that surrounds the thylakoids in a chloroplast, in plants
Chlorophyll A green pigment that is present in most plant cells, that gives plants their green color, reacts with sunlight , carbon dioxide, and water to form carbohydrates
Cellular respiration The process by which cells obtain energy from carbohydrates
Carbon fixation The synthesis of organic compounds from carbon dioxide such as in photosynthesis
Calvin cycle A biochemical pathway of photosynthesis in which carbon dioxide is converted to the 3-carbon sugar glyceraldehyde-3phosphate which can ultimately be used to form glucose
Stomata Small pores usually on the underside of leaves that allow gases and water to enter or leave a plant
C3 plants Plants that use the Calvin cycle after the light reaction in photosynthesis
C4 plants Plants that use the C4 pathway which is a process in which carbon dioxide is bound to a compound to form a four carbon intermediate
CAM plants Plants that use the CAM pathway in which CAM plants take in carbon at night and fix it into various organic compounds and release it during the day (into the Calvin cycle).
Ribulose biphosphate The 5 carbon sugar with two attached phosphates that bonds with carbon dioxide for carbon fixation in the Calvin cycle
3 PGA A 3 carbon intermediate in the Calvin Cycle
G3P- glyceralderhyde-3-phosphate The three carbon sugar produced in the Calvin cycle and ultimately used to make carbohydrates for later use
NADPH and NADPH+ The high and low energy forms of a compound for energy transfer in the two stages of photosynthesis. NADPH is produced in the light reaction and then used up in carbon fixation in the Calvin cycle

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.
