They are all living things so they are all made of cells The Discovery of Cells 1665 Robert Hooke is the first person to describe & name cells by looking at cork. This is what he saw. 1673 Anton van Leeuwenhoek is credited with inventing the first microscope. He was the first person to observe microorganisms & single cells 1833 Robert Brown reported the discovery of the nucleus. 1838 Theodor Schwann, who studied animal cells, & Matthias Schleiden, who studied plant cells, came up with the original cell theory. 1858 Rudolf Virchow showed new cells came from the division of old cells. All living things are made up of cells. The cell is the basic unit of structure & function in all living things. All cells come from other living cells by division. Cells contain genetic information (DNA) that is passed from one cell to another. All energy flow (metabolism) of life occurs within cells. Cells are alive. Cells in multi-cellular organisms have different structures, or parts, that are specialized to do certain functions or jobs. All cells work together to help the organism function as a whole. The characteristics & needs of an organism are in reality the characteristics & needs of the cells that make up the organism. For example, you need water because your cells need water. Major cell functions: extracting energy from food by using water & gases reproducing through cell division in order to grow & repair cells responding & adapting to changes in the environment fighting disease & infection excreting wastes 1/29/15 Starter: 1/20/ Cell Theory Notes Practice : 1.
