1.  In your Bellwork section: ◦ Compare and Contrast “water” and a “plant” ◦ How are they the same? ◦ How are they different? ◦ What makes a “water” a “water?” ◦ What makes a “plant” a “plant?”  We will begin class 7 minutes after the bell  Please work the whole 7 minutes!  It’s going to be a great year! -Mrs. Pollard-

2.  All living things are composed of cells  Cells are the basic units of structure of living things  Cells are the basic unit of function of living things  New cell are produced from existing cells

4.  Brainstorm ◦ characteristics these cells have in common ◦ characteristics these cells have different  Classify the cells you see into two or three groups ◦ Explain what characteristics you used to put each cell in a particular group ◦ Give a name for each group  Use observations to write a definition of a “cell”

5.  Genetic material not contained in a nucleus  Smaller  Simpler; less complicated  Examples: ◦ Archaebacteria – extreme environment ◦ Eubacteria – E.coli

6.  Genetic material is contained in a nucleus ◦ Separated from rest of cell  Complex  Larger  Variety ◦ Single-cell organisms – Amoeba ◦ Multi-cell organisms – plants, animals, fungi, protista
