PHOTOSYNTHESIS

Photosynthesis

QuestionAnswer
What colors are most absorbed chlorophyll pigments? Red and Blue
A green pigment found in the chloroplasts of plants, algae, and some bacteria Chlorophyll
What color is least absorbed by chlorophyll pigments? Green
Cell organelles that absorb energy from sunlight and use it to produce food in plant cells Chloroplasts
Where the light reactions of photosynthesis occur Thylakoid
Products of Photosynthesis Oxygen and Glucose
Reactants of Photosynthesis Carbon dioxide and Water
An organism that obtains organic food molecules by eating other organisms or their by-products. Heterotrophs
Organisms that are able to make their own food Autotrophs
A molecule used to provide energy during the dark reactions. NADPH
NADPH stands for Nicotinamide Adenine Dinucleotide Phosphate Hydrogen
Small openings on the underside of a leaf through which oxygen and carbon dioxide can move Stomata
Equation for Photosynthesis 6CO2 + 6H2O → C6H12O6 + 6O2
Two main stages of photosynthesis Light-dependent reactions and Light-independent reactions
High-energy electrons from excited pigment is transferred thru Primary electron acceptor
Electrons flow, energy from light is needed, thus involves electrons aided by an Acceptor (NADPH+) and a donor (H2O)
When the electrons are passed through and ETC( electron transport chain), these will be transformed into Hydrogen ion to make ATP
Supplies electrons for photosystem Cyclic electron flow
are chemical energy produced in Light-dependent reactions to be used in the Light-independent reactions that produce sugars (glucose) ATP and NADPH
The ATP and NADPH that are produced in the light reaction will be used by Calvin Cycle
After being used, ATP and NADPH will be recycled in light reactions
Phases of Calvin Cycle Carbon Fixation, Reduction, and RuBP Regeneration
Carbon dioxide (CO2) is utilized by plants to make organic compounds in the processes Fixation and Reduction
RuBP stands for Ribulose Bisphosphate

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.
