Prokaryotes Single celled organisms No membrane bound organelles

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

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

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

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

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

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

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

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

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

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

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: Both Found in prokaryotes or Eukaryotes

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

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

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

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