Viruses:
The sizes of viruses are very small, about 10 nanometres to 100 nanometres, which is 10 to 100 times smaller than bacteria. They can only be seen with an electron microscope.
- Viruses are considered to be "on the edge of living and nonliving" because they do not show signs of life until they enter a host cell.
- They exist as independent particles and are made up of a long molecule of DNA or RNA. Surrounded by a protective protein coat.
- Viruses can only reproduce inside living plant or animal cells. They use the host cell’s machinery to create many copies of themselves.
- Once they have multiplied, they destroy the host cell and are released to infect more cells. Viruses cause a variety of diseases in plants and animals.
