Mind Stretcher 11-8-17 ANSWERS MAY INCLUDE: Write (3) things that you know about cells… Don’t look at your notes until you have tried to remember on your own! ANSWERS MAY INCLUDE: They make up all LIVING things Can be unicellular (1) or multicellular (2+) Use a microscope to see them Some have cell walls, some don’t Some have a nucleus, some don’t All have DNA, cytoplasm & cell membrane

All cells must have these Organelles……. Cell membranes Cytoplasm DNA Write this on the TOP RIGHT of your organizer!

Prokaryotic Cells No “membrane bound” organelles No Nucleus Two major types: Bacteria Archaea

Save a little room to sketch the 3 types! Bacteria Most Common Prokaryote Smallest & can live almost everywhere DNA is long and circular (Shaped like a twisted rubber band) Not all Bacteria are bad!! (We have bacteria on our teeth, skin, and in our digestive systems! They help us!!!) Save a little room to sketch the 3 types!

Shapes of Bacteria 3 different shapes: Sphere-Streptococcus Rod-E. Coli Spiral- Cholera Sketch these quickly! Spherical Rods Spiral

Archaea Only write BOLD! Different from bacteria because of Ribosomes Archaea ribosomes are like those of eukaryotic cells Have different cell wall and cell membrane from all other cells Live in EXTREME environments Called “Extremophiles” Heat-Loving Salt-Loving Methane-making Can live near volcanic vents

Eukaryotic Cells Have “membrane bound” organelles Have a Nucleus Largest of all cells 10 times larger than bacteria ALL other living things (that are not bacteria or archaea) are made of eukaryotic cells! Most are Multicellular- (Made of many cells)

Ticket out the Door: Bubble in A for True and B for False: Prokaryotic cells are more complex than eukaryotic cells. Eukaryotic cells are much smaller than prokaryotic cells. Both cells contain DNA. Prokaryotic cells have a nucleus. Archaea is a type of prokaryotic cell.

Mind Stretcher 1. Why are cells small? Larger the cell the more nutrients needed and the more waste created 2. What are the two types of Prokaryotic Cells? Archaea and Bacteria
