Theory
ANTON VAN LEEUWENHOEK

compound
light
microscope
•Bacteria
ROBERT HOOKE

CELL THEORY
1.
2.
3.
All organisms are made up of one or more
cells.
The cell is the basic unit of organization of all
organisms.
All cells come from other cells all ready in
existence.
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?
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.
ORGANISMS
•
Any individual form of life that is capable of growing and
reproducing is considered an organism

environment
Which of the following are organisms?

CHARACTERISTICS OF LIFE
• All living things must have the following things in
order to be considered living
- Cells
- Develop and grow
- Reproduce
- Energy(chemical process)
- Metabolize (waste)
- Response
NEEDS OF LIFE
•
Organisms cannot carry out the activities of life without some
necessities
- Food and Water
- Fats and Proteins
- Air
- Temperature
- Space
