Detailed explanation-1: -Exponential growth happens when an initial population increases by the same percentage or factor over equal time increments or generations. This is known as relative growth and is usually expressed as percentage. For example, let’s say a population is growing by 1.6% each year.

Detailed explanation-2: -Because exponential growth indicates constant growth rate, it is frequently assumed that exponentially growing cells are at a steady-state. However, cells can grow exponentially at a constant rate while remodeling their metabolism and gene expression.

Detailed explanation-3: -The key concept of exponential growth is that the population growth rate-the number of organisms added in each generation-increases as the population gets larger. And the results can be dramatic: after 1 day ( 24 cycles of division), our bacterial population would have grown from 1000 to over 16 billion!

Detailed explanation-4: -The important concept of exponential growth is that the population growth rate, the number of organisms added in each reproductive generation, is accelerating; that is, it is increasing at a greater and greater rate.

Detailed explanation-5: -Exponential growth occurs when the individuals in a population reproduce at a constant rate. As the population grows, the number of people who are reproducing keeps increasing.
