Properties of all cells - growth, metabolism, and evolution. growth - multiply within hours metabolism - capture light energy by doing enzymatic reactions evolution - changes in their DNA that encodes differences that change over time. LUCA - Last Universal Common Ancestor prokaryote - before the nucleus eukaryote - after the nucleu
