Cells Types So what type of cells are there? • Plant & Animal Cells This is a plant cell So what type of cells are there? This is an animal cell Prokaryotes & Eukaryotes • Prokaryotes: – Lack membrane bound organelles in cytoplasm – Circular DNA called plasmid (Circular loop) – Chemically different ribosomes to eukaryotes – Origin: from the Greek meaning Before • Eukaryotes have: – Possess membrane bound nucleus & organelles – Linear DNA (Double helix) – Possess membrane bound organelles in cytoplasm – Origin: from the Greek meaning true (as in nucleus) Prokaryotic Cells This is a Prokaryotic cell. Eukaryotic Cells This is a Eukaryotic cell. Concept Attainment - Cells Is this an … Animal cell? Concept Attainment - Cells Is this an … Animal cell? NO Why?
