general microbiology

QUESTION 1

1. We know fungi are eukaryotic (have membrane-bound nucleus and organelles). Explain three unique ways fungi are different from other microbes (algae, protozoans, bacteria, and archaea). Compare things like cell walls, cell membranes, morphology, reproduction, life cycles.
   
    
   (Words to use in your answer include chitin,      cellulose, peptidoglycan, pseudopeptidoglycan, ergosterol, hopanoids,      cholesterol, mycelium, hyphae, multinucleate, multicellular, unicellular,      nutritional needs, environmental needs, chemoheterotrophy, saprobes,      parasites, free-living, reproductive strategies, spores).

QUESTION 2

1. Algae and protozoans are loosely grouped together as protozoans and are different from plants because they lack certain characteristics of plants. Explain what differentiates algae from plants and two ways they are different from protozoans. Talk about algae being part of our environment and how algae may positively or negatively impact our health or the environment.
   
   (Words to use in your answer: cell wall, cell membrane, chloroplast, plankton, single-cell, multicellular, red tide, toxins, agar, phytoplankton, reproduction, motility, nutrition, feeding strategies)

QUESTION 3

1. 

 Discuss the similarities and differences between animal and bacterial virus multiplication.
 

 (Words/concepts to include in your answer: attachment,  adsorption, penetration, uncoating, synthesis, assembly, persistence,  lysogeny, latency, release).

QUESTION 4 

1. 

  Based upon data from the Human Microbiome Project (HMP), define microbial antagonism and discuss how the various microbial populations keep each other  “in check” with consequences for human health.
