The metazoa represent multi-cellular organisms. And we’re going to
be focusing largely on the biology of metazoan cells this semester, and
we’re going to be spending almost no time on plants. It’s not that
plants aren’t important. It’s just that we don’t have time to cover
everything. And, indeed, the molecular biology that you learn this
semester will ultimately enable you to understand much about the
physiology of multi-cellular plants which happen to be called
metaphyta, a term you may never hear again in your entire life after
today.
