1Heading: Prokaryotic vs. Eukaryotic Cells Homework: Obj. I will be able to tell the difference between a prokaryote and a eukaryote cell.Pages: 11-12Heading: Prokaryotic vs. Eukaryotic CellsHomework:Test CorrectionsCell Analogy Project
2Do First False; there are more than 100 TRILLION (100,000,000,000) 1. There are approximately 10 billion cells in the human body. 2. You have billions of bacteria inside your body right now. 3. Cells are about the size of atoms. 4. It is unhealthy to eat food containing microorganisms (microscopic living things). 5. Microorganisms cannot live in extreme heat or cold.False; there are more than 100 TRILLION (100,000,000,000)True!False! They are WAY bigger!False! (sometimes)False!
3Do First False! They make up 10%! True! True! 6. Bacteria make up about 1 percent of your dry body weight. 7. Microorganisms produce some of the oxygen we breathe. 8.There are over 350 species of bacteria living inside your mouth. 9. Antibiotics kill viruses. 10.The bubonic plague bacteria was responsible for killing one-third of the population in Europe.False! They make up 10%!True!True!False! They kill bacteriaTrue!
4Today’s Objective:SWBAT differentiate between prokaryotic and eukaryotic cells.
5The Two Types of CellsAs microscopes got more powerful, scientists started look at the parts inside cells.An organelle is a small, specialized structure inside a cell.
6The Two Types of Cells All cells can be divided into two categories: Eukaryotic CellsProkaryotic Cells
8Prokaryotic CellsDo NOT contain a nucleus or any other membrane-bound organelles.DNA floats around in the cytoplasmVery small. Smaller than eukaryotic cells.Usually found in bacteria and other unicellular organisms
10Eukaryotic cellsContain a nucleus or any other membrane-bound organelles.DNA located in the nucleus.Very large. Smaller than eukaryotic cells.Usually found in animals, plants, fungus, protist and other multicellular organisms
