Test 9

• Endosymbiosis: theory in which a larger cell engulfed a smaller cell
• Pseudopodia (“false feet”)

  • Lobopods – large, blunt
  • Filopods – thin, branching
  • Axopods – thin, long
• Movement

  • Flagella; one or more
  • Cilia; shorter and more numerous than flagella (hair-like)
  • Pseudopodia (“false feet”)
• Hyphae: long slender filaments
• Mycelium: mass of connected hyphae
• Obligate symbiosis: essential for fungus survival
• Facultative symbiosis: nonessential to fungus survival
• Prohase:

  In Fungi - Nucleus does not break down

  In Humans - Nucleus breaks down
• Commensal relationships: benefit one partner but does not harm the other

  Mutualistic relationships: benefit both partners
• Fungal Relationship

  • Fungi symbioses
  • Obligate symbiosis: essential for fungus survival
  • Facultative symbiosis: nonessential to fungus survival
  • Interactions can be commensal or mutualistic
  • Pathogen – pathogens harm host by causing disease
  • Parasites cause harm to host (do not cause disease)
• Which relationship is Obligate? Commensal or Mutualistic?

  Both can be Facultative or Obligate
