Questions And Answers.
The process of photosynthesis does what? - correct answer. captures light energy
from the sun and converts it to chemical energy stored in sugars and other organic
molecules
Equation for Photosynthesis in Words - correct answer. water + carbon Dioxide + light
energy --> glucose + oxygen
Equation for Photosynthesis - correct answer. 6H2O + 6CO2 + light energy -->
C6H12O6 + 6O2
Water enters plants through? - correct answer. their roots
Carbon Dioxide enters plants through? - correct answer. pores in the leaf called
stomata
Photosynthesis occurs in? - correct answer. chloroplast
Structure of a chloroplast - correct answer. stroma, thylakoid membrane, grana, inner
and outer membrane
Chlorophyll molecules are embedded in the? - correct answer. inner thylakoid
membrane
The primary function of plant pigments is? - correct answer. to absorb solar energy
What happens in light dependent reactions? - correct answer. Energy from sunlight is
absorbed and converted into chemical energy (ATP)
Where do light dependent reactions take place? - correct answer. thylakoid
membranes of chloroplasts
What is a light independent reaction called? - correct answer. Calvin Cycle
What happens in light independent reactions (Calvin Cycle)? - correct answer. Uses
CO2 and the ATP and NADPH from light dependent reactions to produce
sugar/glucose.
, In the Calvin Cycle, ATP is used to? - correct answer. provide the energy for sugar
synthesis
In the Calvin Cycle, NADPH is used for? - correct answer. electrons in the reduction of
carbon dioxide into sugar
Where do light independent reactions (Calvin Cycle) occur? - correct answer. the area
in the chloroplast called the stroma
Leaves are green because? - correct answer. chlorophyll molecules absorb violet-blue
and red light, but reflect or transmit green-yellow light
Process of light dependent reactions - correct answer. chlorophyll absorbs solar
energy and ejects an electron, which is passed down an electron chain, and water is
split, releasing O2
Requirements for light dependent reactions - correct answer. H2O, ADP, and NADP+
Products for light-dependent reactions - correct answer. O2 and the energy-storing
compounds ATP and NADH
Requirements for light-independent reactions (Calvin Cycle) - correct answer. ATP,
NADPH, CO2, a five-carbon sugar called RuBP, and the enzyme rubisco
Products for light-independent reactions (Calvin Cycle) - correct answer.
Glyceraldehyde-3-phosphate (G3P), which can be used to make glucose
Carbon dioxide is fixed during? - correct answer. The Calvin Cycle
How is C4 photosynthesis different from C3 photosynthesis? - correct answer. C3
photosynthesis produces a three-carbon compound via the Calvin Cycle while C4
photosynthesis makes an intermediate four-carbon compound that splits into a three-
carbon compound for the Calvin Cycle
C3 Photosynthesis - correct answer. The most common form of photosynthesis- a
one-stage process in which atmospheric CO2 is used to form 3-phosphoglycerate, a
three-carbon sugar
C4 photosynthesis - correct answer. The two-stage photosynthetic pathway in which
CO2 is first fixed in mesophyll cells to form 4-carbon acids, and then the 4-carbon acids
are broken down into 3-carbon acids in the bundle sheath cells
Examples of C4 plants - correct answer. sugarcane and corn
Why do some plants use C4 photosynthesis? - correct answer. It is an adaptation for
hot and dry weather
