Equation for photosynthesis
|
co2+h20+light -> c6h12o6 +02
|
|
|
Chromotography
|
separates molecules based on their solubility in particular solvents
|
|
|
Solvents used in the chromotography of photosynthetic pigments
|
petroleum ether
acetone - they are nonpolar |
|
|
As a nonpolar solvent moves up the chromatography paper, the pigment moves along with it. The more _____ a pigment, the more soluable it is in a nonpolar solvent and the faster and farther it proceeds up the chromotography paper.
|
Nonpolar
|
|
|
In the photosynthetic pigments experiments what are the different bands and their location?
|
Carotenes- yellow band at the top
Xanthophylls- yellow orange and may be represented by multiple bands Chlorophyll a- blue green band Chlorophyll b- the lowest yellow green band |
|
|
Net photosynthesis
|
measurement of the photosynthesis in excess of the respiratory demand.
net photosynthesis = gross photosynthesis – respiration. |
|
|
Gross photosynthesis
|
gross photosynthesis= net photosynthesis + respiration
|
|
|
rate of photosynthesis
|
(mm/hour)
multiplying gross photosynthesis (mm/10min) times 6 |
|
|
During the calvin cycle reactions of photosynthesis, the plant takes up carbon dioxide and reduces it to a carbohydrate such as glucose. therefore, the carbon dioxide in the solution surrounding Elodea should...
|
disappear as photosynthesis takes place
|
|
|
Phenol red
|
pH indicator that turns yellow in a n acidic solution
|
|
|
When co2 combines with water it forms___. This in the presence of phenol red creates...
|
carbonic acid
yellow solution |
