Ch 8 Photosynthesis

Question 0

Who carries out photosynthesis?

Answer 0

Cyanobacteria
7 groups of algae
All land plants

Question 1

Photosynthesis chemical equation

Answer 1

6co2 + 12h2o ——> c6h12o6 + 6h2o + 6o2

Question 2

Thylakoids membrane

Answer 2

Contains chlorophyll and other photosynthetic pigments

Question 3

Grana

Answer 3

Stacks of flattened sacs of thylakoid membrane

Question 4

Stroma lamella

Answer 4

Connected Grana

Question 5

Stroma

Answer 5

Semiliquid surrounding thylakoid membranes

Releases carbon dioxide

Question 6

Pigments

Answer 6

Molecules that absorb light energy in the visible range

Question 7

Photon

Answer 7

Particle of light. Acts as discrete bundle of energy.
Energy content is inversely proportional to the wavelength of the light
Absorbed by pigments

Question 8

Stage 1 of photosynthesis

Answer 8

Light dependent. Requires light chloroplasts picks up from sunlight.
Makes atp and reduce NADp to nadph

Question 9

Stage 2

Answer 9

Carbon fixation or light independent reactions

Use atp and nadph to synthesize organic molecules from co2

Question 10

Chlorophyll a

Answer 10

Main pigment in plants and Cyanobacteria. Only poignant that can act directly to convert light energy to chemical energy

Absorbs violet blue and red light

Question 11

Chlorophyll b

Answer 11

Accessory pigment. Absorbs light wavelengths that chlorophyll a does not absorb

Question 12

Carbon fixation- Calvin cycle

Answer 12

Builds carbohydrates with energy

Light independent
