Structure & Function of Cells

Structure & Function of Cells

1. Prokaryotes

   • Unicellular
   • Dont always require oxygen
   • Smaller cell size
   • No Nucleus
   • Most dont have membrane bound organelles

2. Eukaryotes

   • Larger cell size
   • Often multicellular
   • Most cells require oxygen
   • Have membrane bound organelles (compartmentalize function)
     • Plasma membrane (gateway to cell)
       • Movement not requiring energy
         • Simple diffusion
         • Osmosis
         • Facilitated diffusion
       • Movement requiring energy
         • Exocytosis
         • Endocytosis
         • Active transport
     • Cell wall (Plants)
     • Nucelus (control center)
     • Microtubules
     • Nucleolus
     • Endoplasmic reticulum
       • Rough
         • Ribosome
       • Smooth
     • Mitochondria
     • Centriole
     • Lysosome
     • Golgi
     • Ribosome (free)
