Nice. A long one


Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

  • Eukaryotic cells
  • have plasma membranes

  • only have cell walls if the cells are plants.

  • They do have a nucleus.

  • They have cytoplasm

Prokaryotic cells

  • have plasma membranes

  • cell walls are usually chemically complexed.

  • don't have a nucleus

  • have cytoplasm

Animal cells

  • only have the plasma membranes.

  • No cell wall

  • have a nucleus

  • have cytoplasm

Plant cells

  • have both the cell wall

  • and have a plasma membrane

  • have a nucleus

  • have cytoplasm
