Fungi: 3 major morphological groups CORRECT ANSWER 1. Multicellular filamentous molds -old food/classic fungus 2. Multicellular fruiting body formers -Fruiting bodies = Mushrooms (fungus is in the soil) 3. Yeasts -single celled Unique properties of Fungus: Cell wall CORRECT ANSWER Thematically similar to bacteria & archaea but contain differences eg: -Chitin: protein; insect shells are made of this -Mixed glycans: similar to peptidoglycan but in a dif order Can also secrete gl...

Prokaryote Characteristics - - No membrane surrounding their DNA; no nucleus - Lack organelles - internal membrane-bound structures - Small; ~1.0 μm in diameter (RBC ~10 μm) - Simple structure Prokaryote Types - Bacteria & Archaea Prokaryote External Structures (3) - Glycocalyces, Flagella and Fimbrae & Pilli Gycocalyx - "Sugar cage" - Polysaccharides - Capsule & Slime Layer Capsule - Hard glycocalyx with consistent structure around prokaryote

Structural part of the cell wall of most bacteria. Composed of polysaccharide chains containing repeat units of N-acetylmuramic acid and N-acetylglucosamine, cross-linked by short chains of amino acids. Correct Answer-Peptidoglycan Found only in the outer membrane of gram-negative cells; lipid A is the active component; they are also called endotoxin. Correct Answer-Lipopolysacharides This gelatinous, sticky substance is usually composed of polysaccharides or proteins that surround the out...
