1. Animal Cells Function of Cells The Cell Theory Animal Cells
Cell Components and Organelles
Cytoplasm
Cell Membrane
Nucleus
Mitochondria
Endoplasmic Reticulum
Golgi Bodies
Vacuoles

2. Function of Cells – In General
Cells work together to keep every living thing alive
Get rid of wastes
Repair and grow
Get energy from food

3. Recall: The Modern Day Cell Theory
The Current Cell Theory
All organisms are composed of one or more cells.
The cell is the basic unit of life in all living things.
All cells are produced by the division of preexisting cells.
Energy flows inside cells
Cells contain DNA which determines the organisms characteristics, and is passed down from one generation to another

4. Cells: An Introduction

5. Animal Cells
Animal cells are are eukaryotic cells meaning they their nucleus is inside a membrane
Animal cells are found inside animals and not plants

6. Main Cell Components Genetic material Cytoplasm Plasma (cell) membrane
Contains the material (blueprint) for life
Cytoplasm
Liquid that fills the cell interior
Holds everything together
Plasma (cell) membrane
Encloses the cell and acts like its skin

7. Main Cell Components
Genetic material
Plasma (cell) membrane
Cytoplasm

8. Animal Cell Components (Organelles)
Cell components are also called organelles
We will cover each organelle below
Cytoplasm – not an organelle but the substance that holds the organelles
Cell Membrane
Nucleus
Mitochondria
Endoplasmic Reticulum
Golgi Bodies
Vacuoles

9. Cytoplasm Gel-like substance that holds the cell organelles together
Mostly water
Where many chemical reactions occur

10. Cell Membrane The double-layer “skin” of the cell
Keeps the cell organelles together
Controls what comes into and leaves the cell

11. Nucleus The cells “brain”
Contains DNA (genetic material) that tells the cell what to do
Usually 1 per cell and is spherical in shape

12. Mitochondria “Powerhouse” of the cell Makes energy out of food you eat
Cells that use more energy like muscle, have more mitochondria
Has an inner and outer membrane

13. Endoplasmic Reticulum (ER)
Network of transportation tubes that move substances around the cell
The “subway” of the cell
Where some proteins are made

14. Golgi Body (Golgi Apparatus)
Works with the ER to collect and process materials to be used by or removed from the cell
Creates mucus for your stomach and intestine ER

15. Vacuoles Temporary “trash can” for the cell
Contains unwanted substances to be removed
Many found inside the cell
