What is a pigment?
|
Chemicals that absorb light (electrons boosted to a higher energy level)
|
|
What happens when light is absorbed?
|
Excites electrons by boosting them to a higher level
|
|
what are the major pigments in plants?
|
Carotenoids,Phycocyanians,Chlorophyll
|
|
Are all wavelengths ( colors ) of light equally used in photosynthesis?
|
No
|
|
Which types of living things carry out photosynthesis?
|
Plants
|
|
where in the cell does photosynthesis happens?
|
Chloroplasts
|
|
what are the starting reactants and end products of photosynthesis?
|
H20 + Co2+ or + Glucose
|
|
what are the steps of photosynthesis?
|
1. Light dependent reactions
ADP to ATP using light energy Occurs in inner membrane of chloroplast Water split into oxygen and H + 2. light independent reactions Uses ATP, Co @ , and H + make glucose can occur in dark if raw material supplied |
|
what are the starting reactants and end products of each step?
|
Light Dependent Reaction
1. Start end Light Independent Reaction 2. |
|
At what stage of photosynthesis is oxygen released?
|
Light dependent reactions
|
|
How is the overall chemical reaction for photosynthesis similar to the overall reaction for cellular respiration?
|
Similar
both used to make energy |
|
How are they different?
|
Cellular respiration ( Plant)
Photosynthesis ( animal) CP : Glucose + o2 --- Co2 + H2o P : H2o + co2--- o2 + Glucose |
