Every living organism has at least one One cell = Unicellular Cell = the body More than one cell = Multicellular Cells have specific functions
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
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
Body Cells like skin cells and muscle cells
Ecoli Bacteria and Binary Fission
Unicellular organism going through binary fission
Bakers Yeast budding
1.The Fundamental Unit of Life is the Cell 2. Cells carry out the functions needed to support life 3. Cells come only from other living cells Unicellular= One cell= body cell Multicellular= More than one cell= cells have specific functions
