Photosynthesis Vocab

TermDefinition
Autotroph an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Light Dependent Reaction the initial stage of photosynthesis that converts solar energy and water into chemical energy
Calvin Cycle a series of light independent reactions that convert atmospheric carbon dioxide into glucose. Powered by ATP and NADPH.
Carbon Fixation Carbon fixation is the process by which photosynthetic organisms convert inorganic carbon dioxide from the atmosphere into organic compounds like sugars.
Chlorophyll a green pigment responsible for the absorption of light to provide energy for photosynthesis
Chloroplast a plastid that contains chlorophyll and in which photosynthesis takes place.
Heterotroph an organism deriving its nutritional requirements from complex organic substances.
Simple Sugar (Glucose) a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
Photosynthesis Reactants Water, CO2, and light energy
Photosynthesis Products Glucose and oxygen
Light Energy Light energy, specifically from the 400-700 nm wavelength range (PAR), is absorbed by chlorophyll and other pigments in chloroplasts to initiate photosynthesis
ADP and NADP+ (role and when produced) ADP and NADP+ are low-energy acceptor molecules produced during the Calvin cycle when ATP and NADPH are used to convert CO2 into sugar. They function as substrates that return to the light-dependent reactions to be recharged into ATP and NADPH.
ATP and NADPH (role and when produced) ATP and NADPH are high-energy molecules produced during the light-dependent reactions that fuel the Calvin cycle. ATP provides chemical energy for sugar synthesis, while NADPH supplies high-energy electrons (reducing power) to convert into glucose

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.
