These are some rough estimates of the relationships between major parameters. We will try to derive or estimate most of them. These factors are very useful for checking answers.
1 cm^3 of cells weighs 1 gram - i.e. they weigh the same as water to a first approximation.
Algal cells are about 30% dry weight.
The dry weight of cells contains approximately 35% carbon by weight.
Chlorophyll ranges from about .5 to 5% of the dry weight of the cell.
C/Chla ratios range from ****
Dark respiration can be estimated as either *** or ***.
