one or more cells
All living cells arise from a pre-existing cell by ________.
division
The cell is the ______________ of structure & function in all living organism.
fundamental unit
The activity of an organism depends on the total activity on ___________.
independent cells
Basic units of the structure & function of living
things.
Cell
He was the first to discover the cell in corks
Robert Hooke
When did Robert Hooke discover the cell
1665
small rooms which monks inhabited
Cellula
The book that Robert Hooke published about cells
Micrographia
a Dutch scientist and known as the “Father of
Microbiology”
- made his own microscope lens, causing him to
be the 1st person to observe human cells and
bacteria.
- His description was the first to provide insight
on the inside of the cell.
-AntoniE Van Leeuwenhoek
-Antoni Van Leeuwenhoek
He is a German Botanist.
- Studied the structure of plant cells
- He was the first to note that plants are made of
cells (1838).
Matthias Schleiden
- He is a German physician & physiologist
- Studied the structure of animal cells
- Proposed that all living things are made of cells.
(1839)

One of the fundamental theories
unifying all of biology
Cell theory
State the 3 postulates of the cell theory
- All organisms are made of one or morecells
- All the life functions of organisms occurwithin cells.
- All cells come from already existing cells.
When did Antoni Van Leeuwenhoek discover bacteria and protozoa.
1674
- Oldest cell type
- Small and simple
- Lack nucleus and organelles
- Single-celled
Prokaryote
Two examples of Prokaryotes
Archea and Bacteria
- Evolved from prokaryotes
- Larger and more complex
- Contain nucleus and organelles
- Single-celled or multicellular
Eukaryote
Eu = ____, Karyo = Nucleus
True
Pro = ____, Karyo = Nucleus
Before
4 examples of Eukaryotes
Fungi, Animals, Protists, Plants
4 parts of the cell that both Prokaryotes and Eukaryotes have.
-DNA,
-Ribosomes
-Cytoplasm
-Plasma Membrane
Is generally believed to be the first investigator to invent the compound microscope.
