I'm just trying to get a hang of this. I hope it works.

Today in lab, we studied the structure of the Volvocine line, which included the Chlamydomanonas cell, Gonium cell, and the Volvox cell. The characteristics of these cells were observed using an optical microscope to view the differences in these cells and noticed varying characteristics within the members of the Volvocine Line.

'Observations'

I observed that the number of cells between the members of the Volvocine Line differed, in that the number of cells for the species, Chlamydomonas was one, while Gonium had a number of approximately thirty-two cells, and Volvox had a numerous number of cells, that was too difficult to count. Not only did the number of cells differ; but the colony sizes of the species differed as well. For example, the Chlamydomonas species had a colony size of 2.5μm, while the Gonium species had a colony size of about 50μm, and the Volvox species had a colony size of 340μm. While observing the differences between the cell species of the Volvocine Line, it was evident to see that the specialization of the cells were different as well. For example, the Chlamydomonas had no observable specialty; however, as the line becomes more complex, the Gonium begins to specialize a little more than the Chlamydomonas, while for the Volvox species, specialization begins.
