Cell theory
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
Definition of Cell

A cell is the smallest unit that is capable of performing life functions


Examples of cells

Red Blood Cell

Nerve Cell

Plant Stem

Bacteria

Amoeba Proteus

Examples of Cells


Cell parts
Cell Parts

aka Organelles


Cell membrane
Cell Membrane

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

  • Double layer

  • Nickname: Border Patrol

  • Analogy: Border

Cell wall
Cell Wall

  • Most commonly found in plant cells

  • Supports & protects cells

  • Nickname: Tree Bark

  • Analogy: brick wall

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


Nucleus
Nucleus

  • Directs cell activities

  • Contains genetic material – DNA

  • Nickname: Control Center

  • Analogy: City Hall


Cytoplasm
Cytoplasm

  • Gel-like mixture

  • Surrounded by cell membrane

  • Nickname: Jello

  • Analogy: atmosphere (air)


Ribosomes
Ribosomes

  • Each cell contains thousands

  • Make proteins

  • Found on Endoplasmic Reticulum & floating throughout the cell

  • Nickname: Ribs!!

  • Analogy: Lumber Mill

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


Mitochondria
Mitochondria

  • Produces energy through chemical reactions – breaking down fats & carbohydrates

  • Nickname: Powerhouse

  • Analogy: Power Plant

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


Vacuoles
Vacuoles

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

  • Usually contains water

  • Much larger in plant cells

  • Nickname: Ziploc bag

  • Analogy: Water Tower

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


Chloroplast
Chloroplast

  • Usually found in plant cells

  • Contains green chlorophyll

  • Where photosynthesis takes place

  • Nickname: greenhouse

  • Analogy: solar panels

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


Lysosome
Lysosome

  • Digestive organelle for proteins, fats, and carbohydrates

  • Transports undigested material to cell membrane for removal

  • Cell breaks down if lysosome explodes

  • Nickname: Garbageman

  • Analogy: Waste Management
