Help with questions on mitosis/meiosis/reproduction

Post by drivingmecrazy » Sun Nov 21, 2010 10:53 pm

I have to answer these in a couple sentences, nothing complicated, but I can only find long explanations that are way too confusing to understand. Could you please help me out?

1. How does cell division in diatoms and dinoflagellates help us to understand how the process of mitosis evolved in eukaryotes?

2. Prokaryotic cell division is a much simpler process than eukaryotic cell division. Identify and explain four factors that make eukaryotics cell division so difficult.

3. The processes of spermatogenesis and oogenesis do not differ in their nuclear division, only in their cytokinesis. Explain.

I know it's something about how in oogenesis an ovum is produced with polar cells that don't really do anything.

Cis or trans? That's what matters.
