Which of the following equations represents the overall chemical reaction for photosynthesis?
6O2+ 6H2O → C6H12O6+ 6O2
C6H12O6 + 6H2O→ 6O2+ 6O2
6CO2+ 6H2O→ C6H12O6+ 6O2
6O2 + 6H2O→ C6H12O6 + 6CO2
Which of these is NOT A TRUE statement about why photosynthesis is important:
It captures and makes the sun's energy available to all species
It helps plants create energy to send to rest of food chain
It turns deadly CO2 into Oxygen for us to breath
It makes the water for our planet
Because plants carry out photosynthesis, they are considered _____.
heterotrophs
consumers
autotrophs
unicellular
Why are plants usually green?
Because the chlorophyll reflects green light
Because the accessory pigments combine to make green
Because the chlorophyll absorbs green light
Because the accessory pigments only absorb green light
Which of the following statements is true about pigments?
Chlorophyll is best at absorbing green and yellow light
Chlorophyll a makes plants either violet or red
Carotenoid is best at absorbing yellow, orange, and red light
Carotenoid is best at absorbing blue-violet light
As the intensity of light increases, the rate of photosynthesis will...
steadily increase
increase exponentially
increase, then level off, then decrease
decrease at first, then increase
What do pigments do?
Absorb specific wavelengths(color) of visible light for energy.
Absorb CO2 in the Stroma to create sugar.
Transports e- in the electron transport chain.
Transports energy between plant cells.
What is water's role in photosynthesis?
To create a liquid solute for oxygen to be made.
To provide electrons and hydrogen, to energize ATP and NADPH.
To help plants with gas exchange, such as diffusion of CO2.
To hydrate plants and removes harmful waste products.

600 nm
680 nm
700 nm
780 nm

Stroma
Stomata
Choloroplast
Mesophyll
In which way are photosynthesis and cellular respiration different?
Cellular respiration stores ATP, while photosynthesis releases ATP.
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
Photosynthesis releases energy, while cellular respiration stores energy.
Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
