• ex: Proteins

organelle

• specialized structure preforming a specific function

common organelles

• cell membranes

• smallest unit of life.

• "building blocks of life"

tissue

• cellular organizational level between cells and a complete organ

• A group of similar cells and its extracellular matrix (supports cell)  working together to do a specific job
