Prokaryotes and Prokaryotic Cells Most functions within the cell No compartmentalization or specialization; single cells function alone (no tissue formation) Generally Examples

Prokaryotes (Archaea and Bacteria) Made of peptidoglycan (sugars and amino acids) Protective shell Clump of DNA Extra loops of DNA Structures that translate DNA and produce proteins Hairs for attachment

Prokaryotic Cellular Movement Mechanical complex of proteins organized into rotary motor

Eukaryotes And Eukaryotic Cells Allow for compartmentalization, specialization, tissue formation (multiple cells working together in a single unit) Generally Examples

______________Cells Made of microtubules help in

______________ Cells made of microtubules help in cell division convert energy from sun into sugar (__________________) through cellular respiration Stores water for

______________ Cells (same thing insect exoskeletons are made of) Spindle pole bodies made of microtubules help in cell division

______________ Early ancestors of animals, plants and fungi All have a single-celled stage in life cycle Sometimes colonial (group together) May be a combination of characteristics

Eukaryotic Cellular Movement SKETCH Ex: spermatozoa, protists Ex: Bronchial and fallopian tube lining, protists Ex: White blood cells, protists
