Page 2: Pigments  Pretty Pigments !

Chlorophyll reflects this color of light.

What is green? 5

Page 3: Pigments  Pretty Pigments !

This is the role that chlorophyll plays in photosynthesis.

What is to absorb light energy?

10

Page 4: Pigments  Pretty Pigments !

This is what happens to electrons in a chlorophyll “a” molecule when they

absorb light.

15What is they are

excited to a higher energy level?

Page 5: Pigments  Pretty Pigments !

This is what we call pigments other than

chlorophyll.

What are accessory pigments? 20

Page 6: Pigments  Pretty Pigments !

This yellow pigment is found in plants but is not directly involved in photosynthesis.

25What is

xanthrophyll?

Page 7: Pigments  Pretty Pigments !

This is the location in the chloroplasts where the light

reactions take place.

5What is the thylakoid

membrane?

Page 8: Pigments  Pretty Pigments !

These are the two products of the light reactions that provide

energy for the Calvin cycle.

What are ATP and NADPH? 10

Page 9: Pigments  Pretty Pigments !

This is the source of the oxygen that is released during

photosynthesis.

What is water?

15

Page 10: Pigments  Pretty Pigments !

The electrons lost by Photosystem 1 are replaced by

electrons coming from here.

What is Photosystem II?

20

Page 11: Pigments  Pretty Pigments !

This process, that happens in the thylakoid membrane, is responsible for

providing energy to produce ATP molecules.

What is chemiosmosis.

25

Page 12: Pigments  Pretty Pigments !

This is the location in the chloroplasts where the Calvin

Cycle takes place.

5What is the stroma?

Page 13: Pigments  Pretty Pigments !

In the Calvin Cycle, the carbon required to make organic molecules

comes from this compound.

What is carbon dioxide?

10

Page 14: Pigments  Pretty Pigments !

In the Calvin Cycle, the hydrogen required to make organic molecules

comes from this compound.

What is NADPH? 15

Page 15: Pigments  Pretty Pigments !

At the start of the Calvin Cycle, 3 molecules of carbon dioxide combine

with this molecule to make 6 molecules of 3-PGA.

What is RuBP?(Ribulose Biphosphate)

20

Page 16: Pigments  Pretty Pigments !

One molecule of this compound is produced during the Calvin Cycle

and used to make glucose or starch.

What is G3P?(Glyceraldehyde 3-Phosphate)

25

Page 17: Pigments  Pretty Pigments !

What is chromatography? 5

This technique is used to separate pigments based on their solubility in a solvent.

Page 18: Pigments  Pretty Pigments !

It is possible to demonstrate that photosynthesis is occurring by measuring the uptake of this

molecule by a plant.

What is carbon dioxide? 10

Page 19: Pigments  Pretty Pigments !

In lab, we demonstrated that photosynthesis was occurring in

geranium leaves by measuring the production of this molecule.

What is starch?

15

Page 20: Pigments  Pretty Pigments !

This pigment traveled the farthest on our chromatography

strip.

What is carotene?

20

Page 21: Pigments  Pretty Pigments !

This is the color of phenol red in a very acidic solution.

What is yellow?

25

Page 22: Pigments  Pretty Pigments !

These are organisms that can make their own food.

What are autotrophs?

5

Page 23: Pigments  Pretty Pigments !

These are organisms that must eat food.

What are heterotrophs?10

Page 24: Pigments  Pretty Pigments !

This is the equation for photosynthesis.

What is 6CO2 + 6H20 C6H1206 + 602

15

Page 25: Pigments  Pretty Pigments !

This is the plant organelle required for photosynthesis.

What is the chloroplast?20

Page 26: Pigments  Pretty Pigments !

These are two types of organisms other than plants that

can perform photosynthesis.

What are some bacteria and some protists?
