1 Early Scientists’ Contributions

2 Anton van Leeuwenhoek First compound light microscope

3 Robert Hooke Coined the term “cell”

4 Matthias Schlieden All plants are made of cells

5 Theodor Schwann All animals are made of cells

6 Rudolf Virchow Cells can only arise from pre-existing cells

7 Cell Theory The cell is the basic unit of structure.
The cell is the basic unit of function. All cells arise from pre-existing cells.

8 Types of Cells Organisms (living things) can be either multicellular or unicellular. Multicellular means made of many cells. Unicellular means made of one cell. Cells may be either prokaryotic or eukaryotic. Prokaryotic cells do not have a nucleus; eukaryotic cells do have a nucleus.

9 Questions... Who used the first microscope?
Who said that plants were made of cells Who coined the term “cell”? Who said that all animals were made of cells? Who said that cells must come from existing cells?

10 State the cell theory... The cell is the basic unit of structure. The cell is the basic unit of function. All cells arise from pre-existing cells.
