The Rate of Population Growth

The number of fission cycles to form 2 daughter cells from 1 parent cell

Generation

2ⁿ, n is the ______

generation number

The initial parent stage consists of _ cell

1

The first generation consists of _ cells

2

The time required for a complete cycle to form two daughter cells from a parent cell via binary fission - “Doubling time”

Generation time

The growth pattern in the bacterial population produces a large number of cells, useful in to express using exponents or logs

exponential growth

CFU’s

colony forming units

A unit used to estimate the number of viable bacteria or fungal cells in a sample.

Colony forming unit

Equation to calculate the size of a population over successive generations

N_t = (N)2ⁿ

N_t what is N

the starting number of cells

N_t what is t

at some point in time

what does the exponent n represent: (N)2ⁿ
