Growth rate

Growth rate

(Science: biology, cell culture, Ecology) The rate, or speed, at which the number of organisms in a population increases.

this can be calculated by dividing the change in the number of organisms from one point in time to another by the amount of time in the interval between the points of time.

The phrase is most often used to describe growth of cells or microorganisms in laboratory cultures and usually expressed as the generation time.

Which is the best calculation for growth?

Hey all, I need to quantify growth of an algal culture. I count the cell-number at the beginning of my exposure ... setup, I can not count cells in-between. If I could, I would determine a growth rate by doing a linear regression of a log-plot of my cell-nr over time and the slope ...
