Photosynthesis Unit Test

Question	Answer
What does photosynthesis require?	water and carbondioxide
What are the outputs of photosynthesis?	Sugar and oxygen
what is the very first step in photosynthesis?	Absorption of light
If the rate of Oxygen release in a plant cell decreases, which organelle could be responsible for this?	The chloroplast
One of the main compounds that a cell uses for energy is?	ATP
In which organelle do the light dependent reactions take place?	The Thylakoid
In which organelle does the Calvin cycle take place?	stroma
The outputs of photosynthesis are	Oxygen Glucose (ATP)
what is the equation of photosynthesis expressed in words?	carbon dioxide + water --> sugars + oxygen
What is the equation of photosynthesis expressed in molecular formulas?	6CO2 + 6 H2O ----> C6H12O6 + 6O2
What is an autotroph?	Plants and other organisms that use light energy to create their own food
What is a heterotroph?	A living organism that obtains energy from the foods that they consume, uses sunlight indirectley
What is ATP?	The Chemical fuel that cells use for energy
What is ADP?	A molecule that is like a partially charged batter, that when it gains a phosphate group, can be used for cellular energy
How does ATP provide energy for cellular activities?	By breaking off a phosphate group.
How do plants absorb the suns energy?	By a pigment called chlorophyll found in the chloroplast of the plant cell
Where does photosynthesis take place?	Within the chloroplast on the thylakoid membrane an in the stroma off the cholorplast
