62 Cell Cycle Edpuzzle Cell division = to make 2 new identical Cells purpose of) 1. to grow - make more cells • cell division 2. to repair and replace. damaged cells/tissue Daughter Cells 12 types of cell division 24 11. Binary fission "dividing in half" -Prokaryptic cell division ex: Bacteria -parent Ocells replicates cell its DNA nucleotide cell wall ✓cytoplasmic membrane (replicated DNA The cytoplasmic membrane elongates, separating DNA molecules 3 Cross wall forms; membrane invaginates 4 Cross wall forms completly. Daughter cells Both daughter cells will have the same genetic information as the parent cell (resting Phase cell normal 2.
