HISTORY OF CELL DISCOVERY

Merchants Used hand lenses to

assess cloth quality

Thin slices of cork

Cells

Invented 1st crude microscope

1) High quality lenses

2) First light microscope

Physician that

studied cancer

Robert Hooke

1500s

Leads to Cell Theory:

1830s

Looked at

and called them

1) Cell is the basic unit of life

2) All living things are made of 1+ cells

3) All cells come from pre- existing cells

Hans & Zaccharias Janssen

y 1600s 1665

All animals are made

of cells

Anton Van Leeuwenhoek

Theodor Schwann

Late 1600s

Invented

Also looked at

Pond water

And called the swimming microbes:

“Animalcules”

Matthias Schleidan

Zoologist that said:

All plants are made

of cells

Botanist that said:

Rudolph Virchow:

Prokaryote

1) Has no nucleus

2) No membrane-bound organelles

3) Simple

4) Evolved first

Bacteria

CELL TYPES

Have the following basic characteristics:

Can

Cells fall into two basic categories:

Eukaryote

Have the following basic characteristics:

1) Has a nucleus

2) Has membrane-bound organelles

3) Complex

4) Evolved later

Example (1):

Examples (4):

Animals,Plants,Fungi,

Protists
