1 Two Types of Cells Prokaryotic Eukaryotic Prokaryotic Eukaryotic

2 What do all cells have in common? ALL cells have a cell membrane, cytoplasm, DNA, and ribosomes ALL cells have a cell membrane, cytoplasm, DNA, and ribosomes Cell membrane – the flexible outer covering of a cell that controls what goes in and out Cell membrane – the flexible outer covering of a cell that controls what goes in and out

3 What do all cells have in common? Cytoplasm – the liquid substance that fills up a cell Cytoplasm – the liquid substance that fills up a cell DNA – cell instructions DNA – cell instructions Ribosomes- a part in a cell that makes protein according to cell instructions Ribosomes- a part in a cell that makes protein according to cell instructions

4 What are the 2 main types of cells? 1.Prokaryotic  Cells that lack a nucleus 2.Eukaryotic  Cells that have a nucleus

5 What is a nucleus? Nucleus – Holds the genetic information of the cell (DNA) and controls most cell activities Nucleus – Holds the genetic information of the cell (DNA) and controls most cell activities

6 Prokaryotic Cells Small, simple cells with a cell membrane, cytoplasm, DNA, & ribosomes Small, simple cells with a cell membrane, cytoplasm, DNA, & ribosomes No nucleus No nucleus Single-celled (unicellular) organisms Single-celled (unicellular) organisms Example: bacteria Example: bacteria

7 Example of Prokaryotic Cells -Bacteria

8 Example of Prokaryotic Cells -Nostoc (Cyanobacteria)

9 Prokaryotic Cell Diagram

10 Eukaryotic Cells Larger more complex cells with a cell membrane, cytoplasm, DNA, & ribosomes Larger more complex cells with a cell membrane, cytoplasm, DNA, & ribosomes Have a nucleus and other organelles Have a nucleus and other organelles Organelles - specialized parts inside a cell with a particular function Organelles - specialized parts inside a cell with a particular function Either single-celled or part of a multicellular organism Either single-celled or part of a multicellular organism Example: plant, animal, fungus, protists Example: plant, animal, fungus, protists

11 Examples of Eukaryotic Cells -Plant and Animal

12 Spirogyra (Protist)
