Obj. I will be able to tell the difference between a prokaryote and a eukaryote cell. Pages: Heading: Prokaryotic vs. Eukaryotic Cells Homework: Test Corrections Cell Analogy Project
Do First 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!
Do First 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! False! They kill bacteria True!
Today’s Objective: SWBAT differentiate between prokaryotic and eukaryotic cells.
The Two Types of Cells As microscopes got more powerful, scientists started look at the parts inside cells. An organelle is a small, specialized structure inside a cell.
The Two Types of Cells All cells can be divided into two categories: Prokaryotic Cells Eukaryotic Cells
Prokaryotic cells (Pro rhymes with NO)
Prokaryotic Cells Do NOT contain a nucleus or any other membrane-bound organelles. DNA floats around in the cytoplasm Very small. Smaller than eukaryotic cells. Usually found in bacteria and other unicellular organisms
Eukaryotic cells (Eu rhymes with True) DNA
Eukaryotic cells Contain 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
