Chapter 8 Test

Bio

QuestionAnswer
Autotrophs organisms (plants) that make their own food; can absorb sunlight directly
Heterotrophs organisms (animals) that cannot muse the sun's energy directly; obtain energy from food they consume
ATP Adenosine Triphosphate; can be recycled; chemical fuel; principle compound that cells use to store/release energy; basic source of energy from all cells
Photosynthesis process in which plants use energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates
Photosynthesis Equation 6CO2+6H2O+light=Glucose(C6H12O6)+6O2
Photosynthesis Reactants sunlight, water, CO2
Photosynthesis Products glucose, oxygen
Pigments plants gather the sun's energy with these light absorbing molecules; create the plant's color
Chlorophyll plant's principle pigment; green color
Thylakoids in chloroplasts; contain saclike photosynthetic membranes
Granum thylakoids that arranged in these stacks
Photosystems clusters of organized chlorophyll and other pigments
Stroma where Calvin Cycle occurs; region outside the thylakoid membranes
NADP+ carrier molecule; compound; accepts/holds two high-energy electrons and H+ ion and carries it throughout the cell; eventually join with H+ ion to become NADPH
Light-Dependent Reactions reaction requiring light; in chlorophyll
Calvin Cycle light-independent reaction; not requiring sunlight; in outer-space of thylakoids; involved with the stroma
Thylakoids in chloroplasts, contain saclike photosynthetic membranes
Photosystem light-collecting units in chloroplasts
Stroma in calvin cycle, region outside thylakoids
NADP+ carrier molecule, bonds with H+ to form NADPH
Light-dependent reactions require light, produce oxygen gas and convert ADP to NADP+ into the energy carriers ATP and NADPH
Calvin Cycle no energy required, used in plants, ATP and NADPH build high-energy compounds that are stored for a long time, used to produce high-energy sugars (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.
