Basic Unit of Life Cell Song

Principles of Cell Theory 1. Cells are basic units of life 2. Biogenesis - All Cells arise from other cells 3. Energy flow (metabolism & biochemistry) of life occurs within cells. 4.. All organisms are made of one or more cells Prokaryotic = 1 cell (Unicellular) Eukaryotic = 2 or more cells (Multicellular) Cell Theory

Surface Area to Volume Ratio The most efficient cells are the smallest Small cells have a GREATER surface area to volume ratio What is the Surface Area to Volume Ratio?
