  1. Two types of cells: Prokaryote Cells And Eukaryote Cells

  2. First, what is a cell?! It took a long time for people to discover cells and figure out what they were all about. They need sophisticated equipment (microscopes) to be able to see cells. Every thing we know about cells we call “cell theory”.

  3. Cell Theory says that…. • All living things are made of cells. 2. Cells are the basic units of structure and function in all living things. In other words, cells are like the building blocks of all living things. 3. New cells are only made from existing cells.

  4. Cells come in all shapes and sizes!

  5. There are two types of cells: Prokaryotic Cells and Eukaryotic Cells

  6. These are two distinct types of cells with STRUCTURAL differences.

  7. Prokaryote Cell A single celled organism that does not have a nucleus. Add this to your vocabulary book

  8. Traits of Prokaryotes:(pro-care-ee-ohts) • They do not have a nucleus, and their genetic material is not stored in the nucleus. • They have only a few organelles. 3. They are less complicated that eukaryotes. • All bacteria are prokaryotes.

  9. Bacteria may be small but they are powerful! During the 14th century, 25% or ¼ of Europe was killed by a killed by a bacteria called the Bubonic Plague, also called Black Death. This bacteria was spread through fleas and rodents.

  10. But at the same time we need bacteria to live! • Bacteria are decomposers and without them all other organisms would not be able to survive. • We use bacteria in our digestive system to help digest our food. There are approximately ten times as many bacterial cells as human cells in the human body! • We could not make cheese or yogurt without bacteria.

  11. Eukaryote Cell A more complex cell with a nucleus and many organelles. Add this to your vocabulary book

  12. Traits of Eukaryotes:(you-care-ee-othts) 1. They all have a nucleus where the genetic material of the cell is stored. 2. They have many organelles that work together to help the cell function.

  13. More traits of Eukaryotes:(you-care-ee-othts) • Eukaryotic cells are much more complex then prokaryotic cells. • They can be just one cell or can make up more complex multi-cellular organisms. 6. All plants, animals, fungi, and protists are eukaryotic cells.

  14. Think – Pair - Share What do you think is the main difference between a prokaryotic cell and a eukaryotic cell?

  15. The nucleus! PROkaryotic cells have NO nucleus & EUKARYotic cells DO CARRY a nucleus.
