Answer:
1. One fundamental difference is that bacterial cells lack intracellular organelles, such as mitochondria, chloroplasts, and a nucleus, which are present in both animal cells and plant cells. ... In addition, prokaryotic cells are usually much smaller than eukaryotic cells.
2.There are two ways bacteria can harm the human body:
toxicity – the bacteria produce toxins which damage specific tissues in the body
invasiveness – the bacteria multiply rapidly at the site of infection and overwhelm the body’s defence mechanisms. The bacteria may then spread to other parts of the body.
3.Benefits of Bacteria
Bacteria provide vital ecosystem services. They are important decomposers. They are also needed for the carbon and nitrogen cycles. There are billions of bacteria inside the human intestines. They help digest food, make vitamins, and play other important roles. Humans also use bacteria in many other ways, including:
Creating products, such as ethanol and enzymes.
Making drugs, such as antibiotics and vaccines.
Making biogas, such as methane.
Cleaning up oil spills and toxic wastes.
Killing plant pests.
Transferring normal genes to human cells in gene therapy.
