Prokaryotes - Single celled organisms - No membrane bound organelles - ex: no nucleus or mitochondria - Free floating DNA - Bacteria are prokaryotic

Eukaryotes - Single or multicellular organisms - Much bigger than prokaryotic cells - Have membrane bound organelles - ex: nucleus, mitochondria - DNA is packed tightly in the nucleus - Animals, plants, protists, and fungi are eukaryotic

What do prokaryotes and eukaryotes both have in common? Cell membrane Both contain DNA Cytoplasm Ribosomes

An organelle (small organ) is a specialized structure inside of the cell. There are many different kinds and all have different functions.

Cell Membrane Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Separates the inside and outside of the cell - Semi-permeable Both

Cell Wall Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: Rigid wall that protects the cell Plants Both

Cytoskeleton Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Framework of the cell 2.Made of microtubules (hollow) and microfilaments (solid) Both

Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.A gel-like substance that is found inside the cell 2. Organelles float in it Both

1.Controls all activities in the cell 2.Contains DNA Function: Found in animal or plant cells: Both Found in prokaryotes or eukaryotes:Eukaryotes

Ribosome Function: Protein Synthesis Found in animal or plant cells: Both Found in prokaryotes or eukaryotes: Both

Function: 1.The site of cellular respiration - Makes ATP 2. The powerhouse of the cell Found in animal or plant cells: Both Found in prokaryotes or eukaryotes: Eukaryotes

Chloroplast Function: 1.Site of photosynthesis - Makes food Found in animal or plant cells: Plants Found in prokaryotes or eukaryotes: Eukaryotes

Endoplasmic Reticulum Smooth ER Function: 1.Lipid Synthesis 2.Regulates Calcium 3.Removes Toxins Rough ER Function: 1.Manufactures proteins and ships them 2.Covered in ribosomes Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

Function: Packages proteins for export from the cell Golgi Apparatus Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: Digestive sacs that break down macromolecules Animal Eukaryotes

Vacuole Function: 1. Holds excess water, food, or waste 2.Small in animal cells 3.Large in plant cells Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

Centrioles Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Assist in cell division 2.Found in the nucleus Animals Eukaryotes
