Photosynthesis uses light energy to synthesise organic molecules Flashcards
1
Q
Absorption spectrum for photosynthesis.
A
- Higher absorption at the blue and red wavelengths.
- Less absorption at green wavelengths
2
Q
Action Spectrum for photosynthesis
A
- Rate of photosynthesis at different wavelengths
- High at red and blue wavelengths
- Low at green wavelengths
3
Q
Relationship between Action Spectrum and Absorption Spectrum and what does that suggest?
A
- Positive correlation between absorption and the action spectrum
- This suggests that the pigments being absorbed are also being used in photosynthesis.
4
Q
4 pigments in photosynthesis
A
- β-carotene
- Xanthophyll’s
- Chlorophyll A
- Chlorophyll B
5
Q
What is a photosynthetic pigment?
A
- Absorbs light energy for photosynthesis
- Specific range of wavelengths
6
Q
Where are chloroplasts found in leaves?
A
- In the palisade layer
7
Q
What are the stages of photosynthesis
A
- Light dependent stage
- Calvin cycle
8
Q
Photosystem naming?
A
P680 = PSII P700 = PSI
9
Q
Light independent stage?
A
