Final answer:
The number of cells after five generations, with a starting point of 50 cells and no cell death, is calculated using exponential growth and results in 1600 cells.
Step-by-step explanation:
If a culture starts with 50 cells and there is no cell death, the number of cells present after five generations can be calculated using the formula for exponential growth, which is 2^n, where n is the number of generations. Since each generation the cells double in number, after one generation there will be 50 x 2, after two generations 50 x 2 x 2, and so on. Therefore, after five generations, you would calculate 50 x 2^5 (50 x 32), resulting in a total of 1600 cells.
