|
Eukaryotic plants and algae are photosynthetic organisms
|
autotrophs - self feeding
|
|
|
Photosynthetic process
|
uses the excited energy in a photon of light to construct a molecule of glucose from water and carbon dioxide.
|
|
|
Oxygen is released
|
as a by-product of photosynthesis
|
|
|
Photosynthesis equation
|
6CO2 +12H2O -----------> (light energy) C6H12O6+6H2O+6O2 |>
|
|
|
Chemical reactions of photosynthesis take place in the organelle called:
|
chloroplast
|
|
|
Chloroplast contain stacked membranes called thylakoids which contain:
|
light-absorbing pigments embedded within their phospholipid bi-layer.
|
|
|
Common pigments are:
|
Chlorophyll A & Chlorophyll B. These pigments will absorb light energy in the form of photons & transfer it along a series of photo systems.
|
|
|
Photosystems use the light energy to form:
|
glucose
|
|
|
Paper chromatography is:
|
a technique for separating dissolved photosynthetic pigments like chlorophyll, carotene and xanthophylls.
|
|
|
Rf Number:
|
Distance moved by a pigment to the distance moved by the solvent front is specific for a given set of conditions.
Rf= distance moved by pigment/ divided by: distance moved by solvent front |
|
|
Photosynthesis is:
|
a metabolic pathway that uses carbon dioxide, water, and sunlight to make oxygen, glucose and water.
|
|
|
Photosynthesis requires pigments:
|
to absorb sunlight like chlorophyll A & B, carotenes, and xanthophylls.
|
|
|
Chromatography:
|
separates chemicals according to molecular weight where distance moved by a chemical is relative to the reference line and the solvent front.
|
|
|
Rf=
|
distance moved by the pigment/distanced moved by solvent front
|
|
|
Convert units:
|
1 inch = 2.54 centimeters (cm)
1 cm = 10 millimeters (mm) 1 mm = 1,000 micrometers (um) 1 um = 1,000 nanometers (nm) 1 nm = 10 angstrom units (A) |
