Study Notes
Viruses
- Viruses are not considered living organisms
- Consists of a nucleic acid core (DNA or RNA) surrounded by a protein coat
- Cannot reproduce outside of a host cell
- Cannot metabolize on their own
- Often infest prokaryotic and eukaryotic cells, causing diseases
Fungi
- Eukaryotic cells (with a true nucleus)
- Mostly multicellular
- Cell walls are composed of chitin
- Obtain nutrients by absorbing organic material from their environment
- Reproduce by releasing spores
Protozoa
- Unicellular aerobic eukaryotes
- Have a nucleus and complex organelles
- Obtain nutrition by absorption or ingestion through special structures
- The largest group of organisms in the world in terms of numbers, biomass, and diversity
- Cell walls are made of cellulose
Bacteria Versus Viruses
- Viruses and bacteria can both cause disease, but they are very different
- Viruses are not considered living organisms, bacteria are
- Bacteria can be beneficial to human and animal health, while viruses are typically harmful
- They spread diseases in distinct ways
