Cell Theory

All living things are made up of cells.

Cells are the smallest working units of all living things.

All cells come from preexisting cells through cell division.

Definition of Cell

A cell is the smallest unit that is capable of

performing life functions.

Cell Membrane

Outer membrane of cell that controls movement in and out of the cell

Endoplasmic Reticulum Moves materials

around in the cell transports of cellular

materials “packaging system”

Cell Wall

Most commonly found in plant cells & bacteria

Supports & protects cells

Nucleus Directs

cell activities

Contains genetic material - DNA

Page 9: Cell Structure  & Function

Nucleolus

Inside nucleus

Contains RNA to build proteins

Page 10: Cell Structure  & Function

Chromosomes

In nucleus Made of DNA Contain

instructions for traits & characteristics

Cytoplasm

Thick Gel-like mixture that protects the internal parts of the cell

Page 12: Cell Structure  & Function

Ribosome

Each cell contains thousands of ribosome

Make proteins and build structures

Mitochondria

Produces energy (ATP) through chemical reactions – breaking down fats & carbohydrates

http://library.thinkquest.org/12413/structures.html

Page 14: Cell Structure  & Function

Lysosomes Digestive 'plant' for

proteins, fats, and carbohydrates

Transports undigested material to cell membrane for removal

Vacuoles

Membrane-bound sacs for storage, digestion, and waste removal

Chloroplast

Usually found in plant cells

Where photosynthesis takes place
