All living things need cells The organelles (or parts) of cells allow the characteristics of life to be metThe organelles (or parts) of cells allow the characteristics of life to be met There are different types of cells which meet these qualifications in different waysThere are different types of cells which meet these qualifications in different ways

There are characteristics that we use to group different cells with different organelles. If cells do not have a nucleus they are called Prokaryotic CellsIf cells do not have a nucleus they are called Prokaryotic Cells If cells do have a nucleus they are called Eukaryotic Cells.If cells do have a nucleus they are called Eukaryotic Cells.

The Nucleus Is the control Center of the cell. It is the Boss and Brain.Is the control Center of the cell. It is the Boss and Brain.

Which of the slides do you believe were Eukaryotes? A.Clostridium botulinum and Bacillus CereuaA.Clostridium botulinum and Bacillus Cereua B.Elodea,Potato, Cheek Cell, Onion Cell, EuglenaB.Elodea,Potato, Cheek Cell, Onion Cell, Euglena

Animal Cells/ Plant Cells are both Eukaryotes! As well As Protists…. Bacteria is not!

Animal Cells/ Plant Cells have many things in common

Some organelles are unique to plant and Bacteria cells Cell Walls are present in plant and bacteria cells for supportCell Walls are present in plant and bacteria cells for support They are like the walls of a house and give the cells a rigid shape!They are like the walls of a house and give the cells a rigid shape!

Which of the Samples do you believe were animal cells? Remember Animal Cells have a less rigid shape/a nucleus/ no chloroplasts A. Clostridium botulinum and ElodeaA. Clostridium botulinum and Elodea B. Cheek CellB. Cheek Cell C. Bacillus Cereus and EuglenaC. Bacillus Cereus and Euglena D. Onion CellD. Onion Cell

Which of the Samples do you believe were plant cells? Remember Plant cells have a rigid shape/a nucleus/ and sometimes chloroplasts A.Clostridium botulinum/ Cheek Cells B.Elodea/Potato Cells/Onion Cells C.Cheek Cell/Bacillus Cereus D.Elodea/Euglena

Why would the potato/Onion cells not have chloroplasts? A.It is not a plant cell B.It is not a part of the plant that photosynthesizes C.I’m not sure

Do you think the Euglena had chloroplasts? A. YesA. Yes B. NoB. No

Bacteria Cells are unique! they are Prokaryotes and have no Nucleus! They keep their DNA in the nucleoid. They have some things in common with plant and animal cells to allow them to live Other things are different

They move/Reproduce in unique ways Some have Flagella to help them move- Like a whipSome have Flagella to help them move- Like a whip They have a pilli which enables them to hook on to other cells and reproduce.They have a pilli which enables them to hook on to other cells and reproduce.
