PHOTOSYNTHESIS

QuestionAnswer
Autotroph An organism that makes its own food using light or chemical energy
Chloroplast Organelle where photosynthesis occurs
Chlorophyll Green pigment that absorbs light energy
Light Energy Energy from the sun used to power photosynthesis
Glucose (C₆H₁₂O₆) Sugar produced during photosynthesis and used for energy
Carbon Dioxide (CO₂) Gas taken in by plants for photosynthesis
Water (H₂O) Reactant absorbed by roots and used in photosynthesis
Oxygen (O₂) Gas released as a byproduct of photosynthesis
Photosynthesis Equation 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
Reactants of Photosynthesis Carbon dioxide, water, and light
Products of Photosynthesis Glucose and oxygen
Light-Dependent Reactions First stage of photosynthesis that requires light
Thylakoid Membrane structure where light reactions occur
ATP Energy molecule produced during light reactions
NADPH Electron carrier produced during light reactions
Photolysis Splitting of water using light energy
Oxygen Source Oxygen released comes from water, not CO₂
Calvin Cycle Second stage of photosynthesis that does not require light directly
Stroma Fluid-filled space where the Calvin cycle occurs
Carbon Fixation Process of converting CO₂ into organic molecules
RuBisCO Enzyme that fixes carbon dioxide
Light Intensity More light increases photosynthesis up to a point
Carbon Dioxide Levels Higher CO₂ increases photosynthesis rate
Temperature Enzymes work best at optimal temperatures
Limiting Factor Factor that slows the rate of photosynthesis
Primary Producers Organisms that form the base of food chains
Energy for Ecosystems Photosynthesis provides energy for most life
Oxygen Cycle Photosynthesis maintains oxygen levels in the atmosphere

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.
