The Cell Theory Notes
Objective Summarize the discoveries that led to the development of the cell theory.
Vocabulary Cell theory
1665 Hooke was the first to identify cells, and he named them.
1674 Because he made lenses, Leeuwenhoek observed cells in greater detail.
1838 Schleiden was the first to note that plants are made up of cells.
1839 Schwann concluded that all living things are made of cells.
1855 Virchow proposed that all cells come from other cells.
Cell theory 1.All organisms are made up of one or more cells. 2.The cell is the basic unit of organization in organisms. 3.All cells come from cells.
An organism can be one cell or many cells like most plants and animals.
Even in complex organisms, the cell is the basic unit of structure and function.
Most cells can divide to form two new, identical cells.
SC.912.L Why do scientists believe that all living things are made of cells?
Welcome to the Cell Chapter 2-3. Microscopes Microscopes --- allowed scientists to view cells. Cells --- The basic unit of life Compound light microscopes.
Life Is Cellular The Cell Theory Early 1600s – Two useful instruments were constructed –T–T–T–Telescope –M–M–M–Microscope.
3.1 Cell Theory KEY CONCEPT Cells are the Basic unit of life.
The Discovery of Cells 1665 Robert Hooke *Used a primitive microscope to examine cork *Saw empty cubicles that he called “CELLS”
Topic: Discovering Cells Date: 10/21/14 Page #: 45 EQ: What are cells?
Contributors to the Cell Theory Robert Hooke (1665)- used a compound microscope to observe thin slices of cork (bark). He observed the cork was made.
Magnifying Cells To see most cells, you need to use a microscope. A microscope has one or more lenses that enlarge the image of an object as though you.
CHAPTER 7 History of the Cell: At least to Our Knowledge.
Cells are the basic units of structure and function in living things Cells keep you alive!! They carry out all lifes functions.
Cells Cells are the basic units of structure and function in living things. Most cells are too small to be seen with the naked eye. The invention of the.
Cell History. History of the Cell O Robert Hooke: Discovered cells O 1665 –Made a simple microscope and looked at a piece of cork (dead cells of oak bark)
EQ: How was the cell theory developed? Do-Now: Use pages to answer the following question. Are all cells exactly alike? Why or why not? Be prepared.
