Cell TheoryOne of the most fundamental
concepts of biology states: All living things are composed
of cells. Cells are the basic units of
structure and function in living things.
New cells are produced from existing cells.

Cell PartsObjective 3: Identify and explain the major functions of the following cell parts:
Nucleus, Cell Membrane, Cell Wall, Chloroplast, Mitochondria, Ribosome, and Vacuole

Use the following colors to color the plant and animal cell pictures:
Plant Cell: 1- light blue 2- brown 5- dark blue 6- black 8- pink 10- purple 11- green 12- orange 13- light yellow
Animal Cell: 1- orange 4- dark blue 5- black 6- pink 8- light blue 9- light yellow 11- purple

Animal Cells vs. Plant Cells
Objective 5: Use two characteristics to distinguish between animal and plant cells.
a. Presence of Cell Wall
b. Presence of Chloroplasts

Cell Types
Objective 5: List and use 3 characteristics to distinguish prokaryotic and eukaryotic cells.
![Page 15: Unit 2 Biology Notes Cell Theory](https://reader035.fdocuments.net/reader035/viewer/2022081507/56816266550346895dd2d11c/html5/thumbnails/15.jpg)
Cell Types Cells are divided into two major categories:
Prokaryotes and Eukaryotes. Major Characteristics of These Types of Cells Characteristic Prokaryotic Eukaryotic
Presence of Nucleus
NoNucleus
Nucleus
Size Small Larger
Complexity Very simple—no membrane-bound organelles*
More complex—has membrane-bound organelles*
