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
