7-1: Life is Cellular Biology 1

If you look closely at different things, you will notice that every living organism is made of cells Introduction

1600: Robert Hooke makes first microscope to look at cork Noticed it was made of small empty “boxes” “boxes” reminded him of monastery rooms, called them cells Discovery of Cell

1600: Anton van Leeuwenhoek used microscope to study pond water Saw tiny living organisms in the water Discovery of Cell

1838: Matthias Schleiden said all plants are made of cells 1839: Theodor Schwann said all animals are made of cells 1855: Rudolf Virchow said new cells can only come from other cells Discovery of Cell

1.All living things are composed of cells 2.Cells are basic units of structure and function in living things 3.New cells are produced from old cells Cell Theory

Cells have 2 categories: 1.PROKARYOTES: unicellular organism lacking a nucleus 2.EUKARYOTES: organism whose cells contain nuclei NUCLEUS (plural-nuclei): the center of the atom which contains the protons and neutrons; in cells, structure that contains the cell's genetic material (DNA) and controls the cell's activities Prokaryotes and Eukaryotes

Small and simple DO NOT HAVE NUCLEUS Can grow, reproduce, respond to environment, and move around EXAMPLE: BACTERIA Prokaryotes

Large and complex DO HAVE NUCLEUS Have lots of structures and membranes inside, VERY SPECIALIZED FOR SPECIFIC JOBS EXAMPLES: Protists, Plants, Animal, Fungi Eukaryotes
