Everything You'll Have Covered

What are the two ways that bacteria reproduce?

~ Bacteria reproduce either asexually or sexually.

What happens to bacteria during asexual reproduction?

~ During asexual reproduction, bacterial cells grow and double in size. They replicate their DNA and divide in half, resulting in two daughter cells with identical genetic material.

What happens to bacteria during sexual reproduction?

~ During sexual reproduction, a temporary cytoplasmic bridge forms between two separate bacterial cells. Genetic material from one bacterial cell is transferred to the other through a process called conjugation.

Why is it not possible for bacteria to take over Earth?

~ Bacteria cannot take over Earth because an inadequate food supply, increasing waste, and extreme temperature and moisture limit their reproduction.
