In cell b2 same cost may or may not appear based on the value in cell a2 (if value changes in a2, then this cost is multiplied with the difference of value in cell (a2-a1), otherwise value of previous cell appears in cell b2.
Each mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.olvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.
Colony-Forming Unit (CFU). A single cell or group of cells that upon plating in or on solid media replicates to form a visible as well as well-defined area of growth. A colony can form starting with any number of cells and that the resulting colony will look pretty much the same unless it was started with an extremely large number of cells. In any case, the cells from which the colony is initiated would be found more or less of at the center of resulting colony.
