Part B. Please turn in typewritten answers to the following questions
1. Asexual reproduction in diatoms occurs when the two valves move slightly apart and
the cell divides in a plane parallel to the valves. A new valve is formed which nests
within the parent valve. What happens to the average cell size in a population of
diatoms reproducing in this manner? How has diatom life history evolved to resolve
this issue of changing cell size? Explain.
2. Many benthic invertebrates produce planktonic larvae. Please provide a rationale for
a meroplanktonic lifestyle. That is, what are the putative advantages of spending only
part of the life cycle in the plankton?
3. Many species of zooplankton will undergo daily vertical migrations, spending the
daylight hours lower in the water column and the evening hours closer to the surface.
Please speculate as to why so many species display this common behavior.
