Patent US 4,010,955

A game board and components for instruction of cellular functions and structures has identical cellular and environmental areas depicted thereon and a continuous playing path around its edge. Chance means direct movements of game pieces along the path, and indicators on the path direct placing of components from a "bank" into cellular environment, cellular cytoplasm or cell nucleus. Each player is assigned a portion of the cellular cytoplasm and environment and fills designated, delineated spaces therein in accordance with moves directed by the game apparatus during play. Filling of blank spaces simulates various scientific and biological functions and structural components found in living plant and animal cells. The structures and functions operative in the game include: active transport, amino acids, adenosine triphosphate (ATP), carbon dioxide, cellular environment, cellular membrane, chlorophyll, chloroplast, chromosome, concentration, cytoplasm, diffusion, deoxyribonucleic acid (DNA), endoplasmic reticulum, enzyme, fat, fatty acid, gene, glucose, glycerol, Golgi apparatus, maltose, mitochondrion, nuclear membrane, nucleus, oxygen, pH, protein, ribosome, synthesis and water.
