Cells carry on the many functions needed to sustain life, including cell growth and development. The genetic information encoded in DNA molecules provides instructions for assembling protein molecules, which are both necessary for producing more cells and performing other cellular functions.
Continuity of Life – Purpose, process, and control of cell division
Variation and Specialization of Cells – Stem cells versus differentiated cells; process and purpose of differentiation; cell-to-cell communication
Multicellular Organization – Embryonic development and organogenesis; types of plant and animal tissues; embryonic versus somatic stem cells; stem cell treatment
