Understanding The Cell: A Study of Life's Fundamental Unit

This unit explores the cell as the foundation of all living organisms on Earth, including animals, plants, fungi, and microorganisms. Key topics include the shared characteristics of these life forms, the essential body processes, and the basic materials involved in metabolism such as oxygen, food, and water. It also delves into histology and cytology, highlighting the structure and function of cell organelles, which were only made visible through the invention of the electron microscope. Discover how cellular structures are vital for different cell types, including specialized cells in muscles, liver, and even teeth enamel.

Presentation Transcript

  1. The Cell • This unit will cover all the major living things on Earth

  2. The Cell • This unit will cover all the major living things on Earth • animals, plants, fungi, and microorganisms

  3. The Cell • WHAT IS COMMON TO ALL THESE GROUPS? .

  4. The Cell • WHAT IS COMMON TO ALL THESE GROUPS? • body process • basic materials involved in metabolism (oxygen, food, H2O etc)

  5. The Cell History • Histology: is the study of special forms of cells and their association and organs.

  6. The Cell History • Histology is closely associated with Cytology • Cytology: The study of cell structure.

  7. The Cell History • The specialized compartments of a cell, the organelles, are so small that it was impossible to study their structure until the electron microscope was developed in 1938.

  8. How is it that we can see cell organelles? • The Nobel Prize in Physiology or Medicine 1974 was awarded jointly to Albert Claude, Christian de Duve and George E. Palade • They were awarded for their discoveries regarding the functional and structural organization of the cell organelles.

  9. How many cells in your body? • See pictures of scientists Claude, De Duve & Palade

  10. How many cells in your body? • 10 trillion cells divided into about 200 different types! • Our muscles are made of muscle cells • Our livers of liver cells • There are even very specialized types of cells that make the enamel for our teeth or the clear lenses in our eyes!

  11. Scientific Method • REVIEW!!
