1 Cell Structure & Function
M.Potestades 

2 STUDENTS WILL: Define Cell Identify the 2 types of Cells
Know the structures and its functions

3 VOCABULARY CELL PROKARYOTIC EUKARYOTIC CELL MEMBRANE CELL WALL NUCLEUS
CHROMOSOME

4 basic unit of life capable of performing life functions.
Cell basic unit of life capable of performing life functions.

5 Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

6 Prokaryotic Eukaryotic
Two Types of Cells Prokaryotic Eukaryotic

7 Prokaryotic No membrane- bound organelles Few internal structures
One-celled organisms, ex-Bacteria

8 Eukaryotic With membrane-bound organelles Multi-celled organisms Plant
Animal

9 “Typical” Animal Cell

10 “Typical” Plant Cell

11 Cell Parts

12 Surrounding the Cell

13 Cell Membrane Protective outer covering of the cell “semi-permeable”
Allows certain substances to go in and out of the cell 

14 Cell Wall found in plant cells & bacteria only
Supports & protects cells Gives its shape Made up of lignin and cellulose

15 Inside the Cell

16 Nucleus Directs cell activities Contains genetic material - DNA

17 Nuclear Membrane Surrounds the nucleus Made up of two layers
Openings allow material to enter and leave nucleus

18 Chromosomes In nucleus Made up of DNA
Contain instructions for traits & characteristics

19 Nucleolus Inside nucleus Contains RNA to build proteins

20 Cytoplasm Gel-like mixture Surrounded by cell membrane
Contains hereditary material Where organelles are found
