Prokaryotic Cells: 

• Prokaryotic- before nucleus, or a cell without a nucleus

 

Prokaryotic Cells are:

• Smaller and Simpler: 

  • 2 kingdoms

  • commonly known as bacteria

  • 0.1 to 10microns in size

  • single celled

• Simply Built: 

  • Capsule- slimy outer coat

  • Cell Wall- tougher middle layer

  • Cell Membrane- delicate inner skin

  • Cytoplasm- inner liquid filling

  • DNA- circular

  • Flagella- locomotion and gathering food 

  • Ribosomes- making proteins

 

Lifestyle:

• unicellular

  • all alone

• colony

  • forms a film

• filamentous 

  • forms a chain of cells

 

Feeding:

• Photosynthetic- energy from sunlight

• Disease Causing- feed on living organisms

• Decomposers- feed on dead organisms

 

 

Eukaryotic Cells:

• good nucleus, or cell with nucleus

 

Eukaryotic Cells are-

• Bigger and More Complicated:

  • 4 kingdoms

  • membrane bound organelles

  • linear DNA within a true nucleus

  • can be multicellu;ar, NOT ALL

  • include plant and animal cells

• Can be Multicellular:

  • whole cell can be specialized for one job 

  • cells can work together as tissues

  • tissues can work together as organs

  • organs to organ systems

  • organ systems to organisms
