photosynthesis

QuestionAnswer
photosynthesis converts solar energy into chemical energy of a carbohydrate
autotrophs they produce their own food
heterotrophs consumers
small holes in the leafs Stomata
chlorplasts the organelle that carry on photosynthesis
Stoma semi fluid around the chloroplast
Flattened sacs thylakoids
grana stacked thylakiods
Chlorophyll pigment in plants; absorbs violet-blue/red light: reflects green light
light reactions photosynthesis using solar energy from the sun in the daytime
Calvin cycles light- independent reaction- carbon fixation; synthesizes organic molecules from CO2 in air and energy in ATP?NADPH; not need light to work takes place in the stroma
mesophyll thick layer of cells rich in chloroplasts
Chlorophyll A main photosynthetic pigment; only pigment that can directly convert light to chemical energy
Chlorophyll B secondary light- absorbing pigment; can absorb wavelengths that chlorophyll alpha can't
Carotenoids absorbs wavelenths not efficiently absorbed bt chlorophyll
porphyrin ring ring structure w/ alternating single/double bonds with MG atom in middle; energy channeled though carbon-bond system
action spectrum relative effectiveness of different light wavelengths on photosynthesis
photoefficiency high absorption efficiency leads to ability to absorb only a narrow bands of light

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.
