3)• Physician that studied cancer• Thin slices of cork• Invented 1st crude microscope• Animals are made of cells

• The cell is the basic unit of life

• Anton Van Leeuwenhoek

• Hans & Zaccharias Janssen

• Pond water• Matthais Schleidan• All living things are

made of 1+ cells• Plants are made of

cells• Cells

• Theordor Schwann• All cells come from

pre-existing cells• Used hand lenses to

assess cloth quality• Robert Hooke• High quality lenses• First light microscope• “Animalcules”

Word Bank:• Organism• Tissue• One-cell• Organ• Cell• Circulatory System

• Red Blood Cell• “Many cells”• Heart• Human• Epithelial Tissue

created by joining cells

that have similar function

or structure

Basic unit of life, stated in Cell Theory

group of tissues that perform a specific

function or groups of functions

collection of organs that

perform a specific function

More complex on individual level; perform all life

functions

Less complex on individual level;

specialized perform diff. tasks
