Cell

CellCell- the smallest unit of lifeCell Theory1. All living things are made of one or more cells2. Cells are the basic structure and function in organisms. 3. All cells come from other cells. ProkaryotesOtherwise known as bacteria.

Average Prokaryote

Prokaryote ShapesThree groups:1) Cocci = spheres2) bacilli = rod shaped3) spirilla = spirals

Beneficial Prokaryotes99% of all bacteria are helpful.Bacteria are used to make cheese, milk, sourdough bread and yogurt.Dead or weakened bacteria and viruses are used for making helpful vaccines.Scientists estimate that bacteria produce nearly half the oxygen found in the atmosphere.Beneficial ProkaryotesHelpful bacteria are used to purify water at sewage treatment plants and to break down oil after oil spills.Bacteria help our bodies with digestion and produce needed vitamins. Bacteria also help us by destroying harmful organisms within our bodies.Base of food web in open oceans.

Prokaryotic ReproductionMost bacteria reproduce using a process called "binary fission." Binary Fission: a single bacterium grows to twice its normal size and then split into two "daughter" cells. The two new cells are exact copies of the original bacterium.

Fun facts about ProkaryotesOne healthy bacterium, given the proper environment, could reproduce into a colony of more than 2 million in just seven hours.There are more microbes on your body than there are humans on the entire planet.An area of skin as small as 6.5 square cm (1 square inch) may be home to more than half a million microbes.There are more bacterial cells in your body than there are human cells.
