Plant and Animal Cells SNC2D
The Cell Theory All living organisms are composed of one or more cells. Cells are the basic units of structure and function in all organisms. All cells come from previously existing cells.
Prokaryote or Eukaryote? Prokaryote A cell that does not contain a nucleus or other membrane bound organelles E.g. Bacteria Eukaryote A cell that contains a nucleus and other organelles, each surrounded by a membrane E.g. Animal or plant cell
Plant Cells vs. Animal Cells No Cell Wall No Chloroplasts Centrioles Lysosomes are common Several Small Vacuoles Cell Wall Chloroplasts No Centrioles Lysosomes are rare 1 Large Vacuole Cells Alive Website
Job of Cells The main job of all cells is to make proteins Different cells make different types Protein production: Ribosome Endoplasmic Reticulum Golgi Apparatus Final Destination of the Protein (may be outside of the cell)
