How is energy released from ATP?
By removing phosphates
The photosynthesis equation
6(co2) + 6(h2o) = (c6h12o6) + 6(o2)
What molecules do plants use to gather the sun's energy?
Why do plants appear green?
the pigments absorb blue-violet and red light waves and the greens are reflected back
Where in the cell does the light reaction occur?
thylakoids and grana
What are the products of the light reaction?
What is another name for the dark reaction?
light-independednt reaction or Calvin cycle
What would happen to a plant if carbon dioxide was removed from the atmosphere?
the plant would suffocate
What affects the rate where photosynthensis occurs?
water availability, temperature, and the amount of light
Why do plants have accessory pigments?
the extra pigments capture more light
What are the three parts of an ATP molecule?
H+ ions, ADP, and a phosphate
What is a granum?
stacks of thylakoids
What is the region outside of the thylakoids in the chloroplasts called?
What are the two stages of photosynthesis?
light and dark reactions
What are the reactants and products of the light reaction?
reactants: light, h2o
products: o2
What are the reactants and products of the dark reaction?
reactants: co2
products: sugars
What were van Helmont's discoveries?
she discovered that there are certain materials out of the soil that are vital to the growth of plants
What were Preistly's discoveries?
he discovered that plants give off a substance (oxygen) that allowed candles to burn longer when a jar is placed over them
What were Ingenhousz's discoveries?
she discovered that the plant must have light to give off the substance (oxygen) in Preistly's experiment
