THE CELL THEORY

1.The Fundamental Unit of Life is the Cell

Every living organism has at least one

One cell = Unicellular Cell = the body

More than one cell = Multicellular Cells have specific functions

Euglenaone cell = unicellular

Amoeba one cell = unicellular

Bacteriaone cell = unicellular

Kittenmore than one cell= multicellular

Daphniamore than one cell =multicellular

Flowermore than one cell = multicellular

2. Cells carry out the functions needed to support life

Unicellular : the cell is the body Takes in food gets rid of waste Asexually reproduces (clones itself)

Multicellular: each cell serves a specific function Blood cell Nerve cell Muscle cell

Kittens have blood cells

Kittens have nerve cells

Kittens have muscle cells

Daphnia have egg cells

Lily pads have cells that make transport tissue (like our blood vessels)

Lily pads have leaf cells

3. Cells come only from other living cells

Cells are constantly making copies of themselves Mitosis: body cells like skin and muscle Meiosis: sex cells (sperm and egg) Binary fission: bacteria and some unicellular

organisms Budding: some unicellular organisms like

bakers yeast

3. Cells come only from other living cells

Body Cells like skin cells and muscle cells
