History of Cell Discovery Chapter 4

Microscope view of cells ► Robert Hooke – first to see cells!  designed microscope that he was able to view cork cells with (1665). ► Named “Cells” because they look like monk quarters they look like monk quarters Cells with stone beds

Microscope view of cells Anton Van Leeuwenhoek – first to see living cells. ► improved design, and was able to view red blood cells able to view red blood cells and bacteria. and bacteria.  Called them "animalicules"

Scientists of Cell Theory ► Theodore Schwann – zoologist who observed that the tissues of animals had cells (1839)

Scientists of Cell Theory ► Mattias Schleiden – botanist who observed that the tissues of plants had cells (1845)

Scientists of Cell Theory ► Rudolf Virchow – reported that every living thing is made up of cells, and that these cells must come from other cells.

Cell Theory 1. All living things are made of one or more cells. 2. Cells are the basic unit of structure and function in organisms.  (the smallest unit that can perform life functions) 3. All cells come from pre - existing cells.

Terms ► Cell – the smallest unit that can carry on the processes of life. ► Unicellular – consists of only one cell ► Multicellular – consists of more than one cell

Basic cell Structures ► ► Cell Membrane – outer boundary ► ► Nucleus – control center ► ► Cytoplasm – stuff between membrane & nucleus

Two Basic Cell Types ► Prokaryotic – lacks internal structures surrounded by membranes.  Has a cell membrane & a cell wall  Has NO nucleus. ► Means “before the nucleus”  Usually Unicellular organisms  Ex: Bacteria

Two Basic Cell Types ► Eukaryotic – contains internal membrane bound structures.  Has a nucleus  Has a cell membrane  Usually multicellular organisms  Ex: Plants, animals, and protists
