Question
Bacteria are small living cells that either damage cells directly or by producing (poisons).
Solution
Bacteria are indeed small living cells. They can cause harm in two main ways:
-
Direct Damage: Some bacteria can attach themselves to the cells of the host organism. Once attached, they can directly damage or kill the cells. This is often done by consuming the host's nutrients, multiplying, and then breaking the cell apart to move on to the next cell.
-
Production of Toxins: Other bacteria can produce toxins, which are harmful substances that can damage or kill cells. These toxins are often responsible for the symptoms we associate with bacterial infections. For example, the bacteria that cause cholera produce a toxin that causes severe diarrhea.
So, in summary, bacteria can harm cells either by directly attacking them or by producing toxins that cause damage.
