Lecture 6 - Microbes and Fungi Flashcards
Prokaryotes
Bacteria and Archaea - Lack a membrane bound nucleus, mitochondria, or any other membrane-bound organelles
Eukaryotes
Contain membrane bound nucleus, mitochondria, and other membrane-bound organelles
Protists
Eukaryotes that are not plants, animals, or fungi
Cell Shapes (Prokaryotes)
Cocci(Spherical), Bacilli(Rod-shaped), Spirochete(Spirals)
Cell Walls (Prokaryotes)
Peptidoglycan (gram +) and Lipids and carbs (gram -)
Projections (Prokaryotes)
Flagella(tail) and Fimbriae (hair/tentacles)
Photoautotroph
-Captures energy from Sun
-Uses CO2 for Carbon
Photoheterotroph
-Captures energy from Sun
-Gets Carbon from organic sources
Chemoautotroph
-Captures energy from inorganic chemicals
-Uses CO2 for carbon
Chemoheterotroph
-Captures energy from inorganic chemicals
-obtains Carbon from organic sources
Proteobacteria
-Gram negative
-Nutritionally diverse
-Pathogens
-Symbiosis
Gram Positive Bacteria
-Gram positive
-Nutritionally diverse
-Pathogens
Cyanobacteria
-Gram negative
-Photoautotrophs
Spirochetes
-Gram negative
-Chemoheterotrophs
-Pathogens

Sporophyte
Produce Spores
Gametophyte
Produce Gametes
Absorption
Secretion of enzymes in fungi that digest plants and animals and then absorb the nutrients
Hyphae
Mass of threadlike filaments
Mycelium
Roots of the hyphae
