Chapter 1: Match Organisms

Prokaryotic, ✖ membrane-bound, cell walls contain peptidoglycan, metabolic diversity (photosynthetic/nonphotosynthetic).

Bacteria

Prokaryotic, cell walls lack peptidoglycan, unique ribosomal RNA, many are extremophiles (adapted to high salt/temperature)

Archaea

Photosynthetic eukaryotes, contain chloroplasts with chlorophyll, possess rigid cell walls.

Algae

Non-photosynthetic, cell walls contain chitin, secrete enzymes for organic nutrient uptake, forms hyphae.

Fungi

Eukaryotic, lacks rigid cell wall, most are motile, ingest organic compounds for energy

Protozoa

Parasitic worms, adult stages visible to naked eye but eggs and larvae are microscopic.

Helminths

Nucleic acid (DNA or RNA) enclosed in a protein coat, obligate intracellular agents, inactive outside of a host cell

viruses

Consist only of a single short piece of RNA, obligate intracellular agents; plant disease

viroids

Infectious proteins consisting of misfolded versions of normal brain proteins, highly resistant to sterilization

Prions

E. Coli

Bacteria

coronavirus and ebolavirus

virus

Giardia lamblia

Protozoa

Saccharomyces cerevisiae and Candida albicans

Fungi

Taenia saginata (Beef tapeworm), Dracunculus medinensis
