Prokaryotes – What are they?

Cells (usually single-celled) with no nucleus

Have no specialized organelles

Usually have: cell wall, cell membrane, ribosomes, genetic material, cytoplasm, and flagella or cilia

Examples: bacteria and archae

Reproduce through binary fission

Get energy through photosynthesis, chemosynthesis, (inorganic chemicals) or digesting other organisms

Eukaryotes – What are they?

Cells with a nucleus and other membrane-bound organelles that perform special functions

Always have a nucleus

May also have: chloroplasts, Golgi apparatus, lysosomes, mitochondrion, plastids, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuoles, and vesicles

Examples: fungi, protists, plant and animal cells

Reproduce by mitosis or meiosis

Get energy through photosynthesis or by digesting other organisms.
