The Cell Theory and the Microscope

The Cell Theory and the Microscope

They remind me of the time I was in jail.

• Robert Hooke (1665) first described cells after
  viewing a thin piece of cork through a primitive
  microscope. Hooke use the word cell to
  describe the honeycomb shapes that he saw. What
  he really saw were the cell walls that surround
  the once-living plant cells in the bark.

Whos your daddy?

• Anton van Leeuwenhoek (1674) commonly known as
  the father of microbiology, used a simple
  microscope to observe living cells in blood and
  in water.

• Robert Brown (1820) used an improved microscope
  to examine plant and animal cells. He was first
  to describe the nucleus of a plant cell.

WHAT THE HECK IS THAT????

• Theodor Schwann and Matthias Schleiden (mid
  1800s) later concluded that plants and animals
  were made up of cells. This information was used
  to develop the CELL THEORY.

No, IM cuter
Im cuter
Oh, go to cells

Four Parts of the Cell Theory
7

• All living cells are composed of one or more
  cells or products of cells.

8
Cells are the functional unit of life.

• All basic chemical and physiological functions
  (repair, growth, movement, immunity,
  communication and digestion) are carried out
  inside of cells.

9
3. Cells are the structural unit of life.

• The structure or form of the overall body of an
  organism is due to the structure and form of the
  cells of which it is composed.

10
All cells come from pre-existing cells.

• Each cell contains genetic material that was
  duplicated and passed to a daughter cell.
