Growth curve | Cellular, Developmental & Population | Britannica
growth curve, in biology, a curve in graph form that shows the change in the number of cells (or single-celled organisms) in an experimental culture at different times. Growth curves are also common tools in ecological studies; they are used to track the rise and fall of populations of plants, animals, and other multicellular organisms over time.
Growth curve (statistics) - Wikipedia
The growth curve model in statistics is a specific multivariate linear model, also known as GMANOVA (Generalized Multivariate Analysis-Of-Variance). [1] It generalizes MANOVA by allowing post-matrices, as seen in the definition.

Exponential growth - Wikipedia
The number of microorganisms in a culture will increase exponentially until an essential nutrient is exhausted, so there is no more of that nutrient for more organisms to grow. Typically the first organism splits into two daughter organisms, who then each split to form four, who split to form eight, and so on. Because exponential growth indicates constant growth rate, it is frequently …
