• Multi-cellular: contain SPECIALIZED cells; some protists, animals, plants, fungi
Types of Living Things• Single-celled: simple; uni-
cellular; bacteria and some protists (amoeba & algae)• Prokaryotic cell =
BACTERIA ONLY; no nucleus; small, simple, self-sustaining
• Eukaryotic cell = all other life; nucleus and other organelles; complex

SPECIALIZATION• Different types of cells form
during your development and perform different jobs in your body• Differ in shape, size, function,
and life span• a.k.a. Differentiation

carry oxygen from lungs to
other body cells
defend body from disease
