Eukaryote Anatomy

General differences between prokaryotes and eukaryotes

  1. Eukaryotes
    • Eucaryotes are typically larger
    • compartmentalized by membrane-bounded sacs or organelles
    • contain a nucleus with multiple chromosomes
    • divide by complex process of mitosis
    • usually have a sexual life cycle involving meiosis
    • View TEM of animal cell
  2. Prokaryotes
    • Procaryotes are typically smaller
    • not compartmentalized
    • do not have a nucleus
    • divide by binary fission
    • no sex life
    • View TEM of bacterial cell
Note: exceptions to these generalizations. Some prokaryotes do have internal compartments. Some eukaryotic cells are very small. Some eukaryotes don't have sexual cycle.

Endosymbiont theory


Fungi: eukaryotic microbes

Yeasts & Molds: 2 common morphologies.

Note: many fungi are dimorphic -- grow as yeasts under some conditions, molds under others.
