<p>How much in depth do we need to know about classification? Do we need to know something like ""Diatoms have glasslike walls"? Please name some phylums that we need to know.</p>
<p>A lot for E… not so much for M. I don’t remember a question that specific coming up but I took M and never bothered looking at E since I knew I was better at molecular than at memorizing things.</p>
