Lab 8 Photosynthesis Flashcards
1) Write the equation for photosynthesis without the
numbers of each molecule, and you can write
“sugar” instead of the formula
2) Write the equation for photosynthesis
3) What structures in a plant require the Light
Dependent reaction?
4) What is the product of a light dependent reaction?
5) What two substances are needed for the light
dependent reaction, in addition to sunlight?
6) How are ATP and NADPH used in a plant?
7) What substance is needed from the atmosphere to
drive the Calvin Cycle?
8) What substance is produced during the Calvin
Cycle which is utilized or stored as starch?
9) What is chlorophyll?
10) What are the two types of chlorophyll molecules?
11) Why do plants appear green?
12) What is the photosynthetic pigment that can be
yellow, orange or red in color?
13) What do the photosynthetic pigments do with light
energy?
14) Where is chlorophyll a found?
15) Where is chlorophyll b found?
16) What is the function of the antennae assembly?
17) Where is the antenna assembly located?
18) What increases the photo spectrum of the plant?
19) What happens when chlorophyll molecules are
exposed to light energy?
20) How can photosynthetic rates be altered?
21) What two components give plants the capacity to
undergo photosynthesis and cellular respiration
simultaneously?
22) What is formed when combining CO2 with H2O?
23) What happens when CO2 is combined with water?
24) Carbonic Acid may separate into which two ions?
25) What does the following equation describe?
26) Sugars + oxygen <----> CO2 + H2O <---> H2CO3
<---> H+ + HCO3
27) What photosynthetic pigments are utilized most
for photosynthesis by green plants?
28) What photosynthetic pigments are utilized least for
photosynthesis by green plants?
CO2 + H2O + sunlight = sugar + O2 + H2O
6 CO2 + 12 H2O + sunlight = C6H12O6 + 6 O2 + 6
H2O
photosynthetic pigments
Oxygen (O2)
ATP and NADPH
to drive the Calvin Cycle to produce chemical energy
CO2
GAP
The primary photosynthetic pigment of green plants.
A and B
The chlorophyll molecules absorb the all of the colors
of the visible light spectrum except green (which is
reflected)
Carotenoids
They convert light energy to glucose.
It is found in the reaction center of a photosystem
It is found in the antennae assembly
Absorbs light energy and passes high energy electrons
to chlorophyll a for energy production
It is located in the plant cell membrane
the antenna assembly
Carbon dioxide and water can be utilized to form sugar
and oxygen respectively
Change the intensity of light
Chloroplasts and Mitochondria.
Carbonic Acid (H2CO3)
It becomes acidic.
Hydrogen ion (H+) and Bicarbonate ion (HCO3)
The production and dissociation of carbonic acid
chlorophyll a
chlorophyll b
Carotenoids

29) What method is used in order to saturate a
substance in a test tube with CO2?
30) Why do you not want to put test tubes too close to
light sources when dealing with photosynthesis?
31) Why is pigment separation possible?
32) How do you handle chromatography strips?
33) Why must you be careful with chromatography
strips?
34) What must you allow before adding extra solvent?
35) What is the hypothesis being tested in this
experiment?
36) What were the bubbles off by Elodea in this
experiment?
37) What can you conclude about the light intensity
and the photosynthesis rate?
38) During the summer months, farmers in Alaska can
grow much larger (heavier) pumpkins than farmers
in California. Explain why this is possible.
39) Graph the effects of light intensity and the
photosynthetic rate. Do not forget all the
components of a graph.

dark at the end of the experiment?
43) Is the solution acidic or basic? Explain your
answer
44) What is the purpose of the accessory pigments
found in plants?
Blow through a straw.
You may accidentally damage the leaves from the
heat.
Varying solubility in given solvents.
By the edges only.
The oils from your fingers will affect the separation of
the pigments.
Allow drops to dry.
