Characteristics of Life

All living things share some basic properties Cells ¡ Organization ¡ Energy Use ¡ Homeostasis ¡ Growth and Development ¡ Reproduction ¡

Cells ¡ Basic unit of life l l Human skin Carry out the functions of life All organisms have 1 or more cells. Plant leaf Bacteria

Cells ¡ Unicellular organisms l l l Made of 1 cell Each cell has everything necessary for life Include bacteria and protists
