Presentation transcript:

Starting at the End…

Cell Theory All organisms are made of cells Cells are produced by cells The cell is the most basic unit of life

What is a Theory? How is it different from a Law? Other PPT

FYI It took 174 years for the cell theory to be accepted because scientists had to look at many specimens before they could say that all living things are made of cells.

Who Am I? Hans and Zacharias Janssen Robert Hooke *Divide paper into 6 sections. In each section, list a person, their contribution to the study of cells and the date associated with this contribution. Hans and Zacharias Janssen Robert Hooke Anton van Leeuwenhoek Matthias Schleiden Theodor Schwann Rudolph Virchow

The Bigger Picture There is more to the story of the Cell Theory than a text book will let on… Ted-Ed: The Whacky History of the Cell Theory

Extended Timeline You are going to create a timeline on construction paper that includes: Title – “Cell Theory” All 6 people A caption for each (contribution) Year of contribution A picture for each person that represents them or their contribution to the cell theory COLOR, neatness and creativity *Due Thursday!!! (22 points)

Rubric Cell Theory Timeline Name: ______________________ Title (1 point) __________ 6 people w/correct year (6 points) ___ 6 accurate captions (6 points) ________ 6 related pictures (6 points) _________ Color/Neatness (3 points) ____ Total (out of 22) ____________

Question: The cell theory was first proposed in 1838. Evidence obtained through additional scientific investigations resulted in the current cell theory. Which statement describes a component of the original cell theory that was removed because of new scientific knowledge? All living things are made of cells All cells come from other preexisting cells Cells form through spontaneous generation Cells are the basic structural and functional unit of life *
