Prokaryotes and eukaryotes We Are Learning To (WALT): Learning Objectives – • What are eukaryotic and prokaryotic cells? What I’m Looking For (WILF): ALL: Identify plant, animal and bacterial cells and classify them as eukaryotic or prokaryotic cells (3) MOST: Label diagrams of bacterial cells. (5-) SOME: Describe the differences between eukaryotic and prokaryotic cells in terms of structure and size. (6) Date: 30/04/2017 KEYWORDS: • • • • • • Eukaryotic Organelle Prokaryotic Plasmid DNA Flagellum DO NOW: What cells do you know ? List as many cells as you can in 1 minute Eukaryotes VS Prokaryotes 30-Apr-17 Learning Objective: How are bacteria cells the same and different to plant an animal cells? Success Criteria: 1) What is a eukaryotic cell and prokaryotic cell? 2) What organelles or features do prokaryotic cells have? 3) What are the similarities and differences between prokaryotes and eukaryotes? LANGUAGE FOR LEARNING Eukaryote, Prokaryotic, Membrane-Bound, Nucleus, Organelle, Plasmid, DNA, Flagellum, Cell Theory Cells are the basic units of living organisms. The cell theory states that: – All living things are made of one or more cells. – Cells are the basic unit of structure and function in living things. – All cells come from other cells. Draw a VENN DIAGRAM IN YOUR BOOOKS TO HIGHLIGHT THE SIMILARITIES AND DIFFERNCES https://www.youtube.com/watch?v=RQ-SMCmWB1s Eukaryotic cells Cell that have membrane-bound organelles such as mitochondria and nucleus. • Plant and animal cells have a cell membrane, cytoplasm and genetic material enclosed in a nucleus. • Plant cells contain some organelles that are not found in animal cells. Prokaryotic cells Unicellular organisms such as bacteria that do not have membrane-bound organelles • Bacterial cells are much smaller than eukaryotic cells. • They have cytoplasm and a cell membrane surrounded by a cell wall. • The genetic material is not enclosed in a nucleus. • It is a single DNA loop and there may be one or more small rings of DNA called plasmids. Draw the bacterial cell and label it Cell membrane Cell membrane Prokaryotes and Eukaryotes Prokaryotes - Missing a Nucleus • Prokaryotes do not have an organized nucleus. Eukaryotes - Cells with Parts • Eukaryotic cells have an organized nucleus. Construct a table to compare the structure of plant, animal and bacterial cells. Structure Cell membrane DNA Cytoplasm Mitochondria Nucleus Cell wall Prokaryote yes/no Eukaryote yes/no What cell is it found in? Write a paragraph to compare a bacterial cell with an animal cell in terms of structure and size. • Be ready to read it out to the class 2 The diagram shows two cells, a bacterial cell and a plant cell. 2 (a) (i) Both the bacterial cell and the plant cell contain ribosomes. What is the function of a ribosome? ......................................................................................................................... ......................................................................................................................... (1 mark) 2 (a) (ii) The plant cell contains mitochondria but the bacterial cell does not contain mitochondria. Give one other way in which the plant cell is different from the bacterial cell. .........................................................................................................................
