Understanding microbes

Bacteria

• There is no nucleus or organelles.
• Bacteria has a plasmid instead of DNA.
• the genes in the plasmid make the bacteria resistant to some antibiotics.
• bacteria reproduce by binary fission

viruses

• smallest of the microbes.
• they multiply in the cells of living orgANISMS.
• VIRUS IS EITHER MADE OF DNA OR RNA.
• VIRUSES ARE COVERED IN PROTEIN COAT CALLED CAPSID.

fUNGI

• THEY CAN BE SINGLE OR MULTICELLULAR ORGANSIMS
• THEY ARE DECOMPOSERS.
• FUNGI CAN BE USED TO MAKE ANITBIOTICS AND VACCINES.
• SOME FUNGI CAUSE DISEASES IN ANIMALS AND PEOPLE.

PROTOZOA

• SINGLE CELLED ORGANISM
• THEY LIVE IN FRESH WATER, OCEAN, AND SOIL.
• THEY EAT BACTERIA AND SMALL PROTOZOA
• THEY USE PSEUDOPODIA TO EAT.
