Photosynthesis Vocabulary

QuestionAnswer
Autotrophs Organisms that are able to use light energy to make their own food
Heterotrophs Organisms that obtain there their energy by consuming other organisms.
Energy the ability to do work.
ATP a chemical compound used by cells to store and release energy; consist of 1 adenine, 1 ribose, and 3 phosphates.
ADP a chemical compound that stores available cell energy by adding a phosphate group to itself thus making an ATP molecule.
Glucose a 6-carbon sugar; the product from photosynthesis (Calvin Cycle)
Photosynthesis the use of energy of the sun to convert water and carbon dioxide into high-energy sugars and oxygen.
Pigments light absorbing molecules
Chlorophyll the principal pigment in plants that absorbs light and raises energy levels of electrons.
Chloroplast Organelle found in plants that captures the energy from sunlight and converts it into chemical energy
Thylakoids sac-like disc found in the chloroplast which contains a photosynthetic membrane
Stroma the fluid found outside the thylakiod contain within the chloroplast
Granum a stack of thylakiods found with the chloroplast
Light-dependent reactions reactions of photosynthesis that uses energy from the sun to produce ATP and NADPH
Calvin Cycle reactions of photosynthesis that uses energy from ATP and NADPH to build sugars (glucose)
Photosystems light collection units of the chloroplasts; Photosystem I and Photosystem II
NADP+ a carrier molecule that transfers high-energy electrons from chlorophyll to help drive the Calvin Cycle
ATP Synthase a large protein that uses energy from the diffusion of H+ ions to bind ADP to a phosphate group to form ATP.
Electron Transport System a series of proteins that uses the electrons energy to actively transport H+ ions to an area of low concentration to an area of high concentration (from stroma to inside the thylakoid)
Synthesis to make a product

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.
