1. Photosynthesis: Occurs in: Producers (examples plants/some bacteria/algae) Chloroplasts of leaves are major sites for photosynthesis. Affected by: Temperature, Light Intensity, CO2 & O2 Carbon dioxide + water + light energy  glucose + oxygen 6CO2 + 6H2O + light energy  C6H12O6 + 6O2
is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later used for the organisms' activities.

2. Physics Review- From 1st pg of notes
If you pass white light through prism glass, you can see a rainbow colors which are considered the COLOR SPECTRUM
7 colors in the spectrum are abbreviated as ROYGBIV
ROYGBIV, red, orange, yellow, green, blue, indigo, violet
R - O - Y - G - B - I - V 750nm nm low energy high energy Infrared Ultraviolet
Light travels in wavelengths (distance between consecutive crests of a wave)

3. Chlorophyll is made up of a combination of pigments: Carotene= orange
Xanthophyll = yellow accessory pigments
Chlorophyll b= blue-green
Chlorophyll a= yellow-green (direct use in photosynthesis)
This combination reveals a green color!!
Chloroplasts absorb red and blue light, which are most affective in photosynthesis.
Green light is reflected, which is why the leaves appear green.
