  1. KEY CONCEPT Cells are the Basic unit of life.

  2. The cell theory grew out of the work of many scientists and improvements in the microscope. • Many scientists contributed to the cell theory.

  3. The cell theory grew out of the work of many scientists and improvements in the microscope. • Many scientists contributed to the cell theory. • More was learned about cells as microscopes improved.

  4. The cell theory grew out of the work of many scientists and improvements in the microscope. • Many scientists contributed to the cell theory. • More was learned about cells as microscopes improved. • The cell theory is a unifying concept of biology.

  5. Early studies led to the development of the cell theory. • The Cell theory has three principles. • All organisms are made of cells.

  6. Early studies led to the development of the cell theory. • The Cell theory has three principles. • All organisms are made of cells. • All existing cells are produced by other living cells.

  7. Early studies led to the development of the cell theory. • The Cell theory has three principles. • All organisms are made of cells. • All existing cells are produced by other living cells. • The cell is the most basic unit of life.

  8. Prokaryotic cells lack a nucleus and most internal structures of eukaryotic cells. • All cells share certain characteristics.

  9. Bacterium (colored SEM; magnification 8800x) • Prokaryotic cells lack a nucleus and most internal structures of eukaryotic cells. • All cells share certain characteristics. • Cells tend to be microscopic.

  10. cell membrane Bacterium (colored SEM; magnification 8800x) • Prokaryotic cells lack a nucleus and most internal structures of eukaryotic cells. • All cells share certain characteristics. • Cells tend to be microscopic. • All cells are enclosed by a membrane.

  11. cell membrane cytoplasm Bacterium (colored SEM; magnification 8800x) • Prokaryotic and eukaryotic cells. • All cells share certain characteristics. • Cells tend to be microscopic. • All cells are enclosed by a membrane. • All cells are filled with cytoplasm.

  12. There are two cell types: eukaryotic cells and prokaryotic cells.

  13. nucleus cell membrane • There are two cell types: eukaryotic cells and prokaryotic cells.

  14. nucleus cell membrane • There are two cell types: eukaryotic cells and prokaryotic cells.

  15. cell membrane • There are two cell types: eukaryotic cells and prokaryotic cells. Prokaryote means “first cells”. Eukaryote means “new cells”.

  16. cell membrane cytoplasm • There are two cell types: eukaryotic cells and prokaryotic cells.

  17. Read the section in 3.1 detailing the two types of cells: prokaryotes and eukaryotes - Page 72 • Make a poster explaining their similarities and differences. • Include: • Color • Structures • Examples • Write a sentence explaining prokaryotes and eukaryotes • Focus on the advances of the Eukaryotes (ie: “new and improved!”)
