Cells are the smallest unit of life. Cells in multicellular plants ... cells with the same function group together. For example, millions of muscle cells make up muscle tissue.

The face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...
