• Cells Discovered by robert hooke• How science works– Curious so he explored– Discovery
More scientists
• Leeuwenhoek• Discovered Protists
Cell theory
Combination of discoveries lead to cell theory
• All organisms are made of one or more cells.• The cell is the basic unit of all living things.• All cells come from existing cells.
All organisms are made of one or more cells.
• Unicellular– Bacteria– Protists
• Simple organisms– Reproduce quickly– On earth first– Die easy– Can cause disease/Be a parasite– Also can be beneficial
All organisms are made of one or more cells.
• Multicellular. – Many cells– Cells form tissues and organs– Humans– More stable organisms– Grow over a longer time.
The cell is the basic unit of all living things.
• Cells are like individual pieces. Combine to make life.
• Cells work together to do a job
All cells come from existing cells.
• Cells divide to make new cells. • Cells can combine to make new offspring.

• Cells cant just appear
