Cells: Structure and Function
Chapter 6
![Page 2: Cells: Structure and Function Chapter 6. The People Jansen made the first microscope. Anton van Leewenhoek discovered microorganisms. Hooke discovered.](https://reader036.fdocuments.in/reader036/viewer/2022070411/56649f465503460f94c6851e/html5/thumbnails/2.jpg)
The People
• Jansen made the first microscope.• Anton van Leewenhoek discovered
microorganisms.• Hooke discovered cells.• Virchow and Schleiden developed the cell
theory.

First cells were Prokaryotes
![Page 4: Cells: Structure and Function Chapter 6. The People Jansen made the first microscope. Anton van Leewenhoek discovered microorganisms. Hooke discovered.](https://reader036.fdocuments.in/reader036/viewer/2022070411/56649f465503460f94c6851e/html5/thumbnails/4.jpg)
Prokaryotes• No nucleus or orgnelles.• Nucleoid region is where DNA is located.• Ribosomes change genetic info. into proteins.• Flagella for movement• Cell wall, support and protection.• Plasma membrane control entry/exit.• Capsule protection, may cause disease.• Pili allow attachment to host.

Prokaryotic cells needed to do all life functions.
• Digest• Reproduce• Move• Remove wastes
• Single cells must do it all.

Eukaryotic cells
![Page 7: Cells: Structure and Function Chapter 6. The People Jansen made the first microscope. Anton van Leewenhoek discovered microorganisms. Hooke discovered.](https://reader036.fdocuments.in/reader036/viewer/2022070411/56649f465503460f94c6851e/html5/thumbnails/7.jpg)
Eukaryotes
• Cells with oganelles doing specific tasks.• Appear long after first prokaryotes• Endosymbiotic theory.
– Mitochondria….chromosomes

Single cell

Cooperation
• Cells living together and gaining some survival advantage.
• Colonial Volvox

Volvox Colony
![Page 11: Cells: Structure and Function Chapter 6. The People Jansen made the first microscope. Anton van Leewenhoek discovered microorganisms. Hooke discovered.](https://reader036.fdocuments.in/reader036/viewer/2022070411/56649f465503460f94c6851e/html5/thumbnails/11.jpg)
Volvox
• Many cells living as a single organismSize = protection
• Offspring protected within.• No specialized cells.

More Specialization
• Specialized cells for different tasks.• Do not do everything.• More Efficient• Cells specialize into Tissues, layers of cells.
