ACCURATE!!
The process of photosynthesis captures ____ and converts it to ____. -
(ANSWER)Light energy from the sun
Chemical energy stored in sugars and other organic molecules
What is the general equation for photosynthesis? - (ANSWER)water + carbon
dioxide + light energy --> glucose + oxygen
OR
6H2O + 6CO2 + light energy --> C6H12O6 + 6O2
How does carbon dioxide enter plants? - (ANSWER)Through pores in the leaf
called stomata
How does water enter plants? - (ANSWER)Through their roots
Where does photosynthesis occur in a plant? - (ANSWER)Chloroplasts
What is the structure of a chloroplast? - (ANSWER)Stroma
,2
Thylakoid membrane
Grana
Inner membrane
Outer membrane
What is embedded in the inner thylakoid membrane? - (ANSWER)Chlorophyll
molecules
What is the primary function of plant pigments? - (ANSWER)To absorb solar
energy
Compare and contrast light dependent reactions and the Calvin Cycle (light
independent reactions) - (ANSWER)Light reactions use the energy of sunlight to
make the energy-storing compounds ATP and NADPH.
The Calvin Cycle reactions use the energy stored by the light reactions to make
G3P, which can be used to make glucose.
Why are leaves green? - (ANSWER)Chlorophyll molecules absorb violent-blue and
red light and they reflect or transmit green-yellow light
What are the processes of light dependent reactions? - (ANSWER)Chlorophyll
absorbs solar energy and ejects an electron
This is passed down an electron transport chain
, 3
Water is split, releasing O2
What are the requirements for light dependent reactions? - (ANSWER)H2O
ADP
NADP+
What are the products of light reactions? - (ANSWER)O2
Energy-storing compounds ATP and NADH
What are the requirements for the Calvin cycle reactions? - (ANSWER)ATP
NADPH
CO2
Five-carbon sugar called RuBP
Enzyme Rubisco
TRUE OR FALSE: Carbon dioxide is fixed during the Calvin cycle - (ANSWER)TRUE
What is the product of the Calvin cycle? What can this be used to make? -
(ANSWER)Glyceraldehyde-3-phosphate (G3P)
Glucose
