Photosynthesis
Conversion of light energy from the sun into chemical energy.
Photosynthesis Formula
6CO2 + 12H2O + Light Energy --> C6H12O6 + 6O2 + 6H2O
What two stages does photosynthesis take place?
1. Energy Capturing Reactions (Light-Dependent Reactions)
2. Calvin Cycle
Light energy is used...
To split water and energize the electrons of chlorophyll molecules
Light energy
Kinetic energy with the ability to make types of light visible to the human eye
Light is composed of what
Wavelengths
Electromagnetic Spectrum range
Ranges between 1000 m - 1 nm
Order of rays in electromagnetic spectrum from 1000m to 1 nm
Radio
Infrared
Visible Light
, UV light
X rays
Gamma Rays
Range of Visible light
740 nm to 400 nm
Colors of visible light from 400 - 700 nm
Violet
Blue
Green
Yellow
Orange
Red
Why do green plants appear green?
Plants contain chlorophyll, a green pigment, which absorbs blue and red light and
reflects green light
Why do black objects appear black?
They absorb all wavelengths of visible light, and nothing reflects back to the human eye
Chromatography
A process that separates complex mixtures into their component parts based on their
solubility in different kinds of solvents
Pigment
A compound that absorbs light
Types of pigments found in chloroplasts
