The document outlines the key contributors to the development of the cell theory. It summarizes the major discoveries of Brown, Dujardin, Kolliker, Leeuwenhoek, Purkinje, Schleiden & Schwann, and Virchow that helped establish that cells are the fundamental unit of life. It then lists the main points of the cell theory: that all living things are made of cells, cells are the basic functional units of life, and cells only arise from preexisting cells through division.

4. -was able to observe tiny
animals called,
“animalcules”

5. Discovered the presence of
NUCLEUS within the
cells

6. -French biologist
-SARCODE = gelatinous
fluid in the cell

7. -coined the word
PROTOPLASM
LIVING MATERIALS in the
cell

8. - plants and animals
are composed of cells

9. - Coined the term
CYTOPLASM

10. -”omnis cellula e cellula”
=“cells divide and form new
cells”

11. The cell theory states that:
1. ALL living things are made up of cells.
2. The cell is the FUNDAMENTAL unit that
gives the structure and function of life.
3. Cells come from the DIVISION of preexisting
cells.

12. 1. The ENERGYof organism is formed in the
cells.
ATP
Adenosine
triphosphate

13. 2. Organisms can be made of one or more cells.
3. DNA, which is the blueprint of life, can be
replicated (copied) and passed from cell to
cell through cell division.

15. MITOSIS

17. 4. An organism carrying certain chemical
compositions of cells is the same with the species
where it belongs.

19. 5. The activities in an organism are dependent on
the activities done by its cells.
