:5、 STRUCTURE AND FUNCTION OF THE CELL

Q6:A major theme in biology (and therefore a common free-response question topic) is that function dictates form and vice versa. As a result, one would expect that all cells do not look alike. And they do not. The nerve cell, whose purpose is to send electrical impulses, is long and spindly. Cells that store fat are rounded, large, and distended. Cells that make up a tough peach pit resemble square building blocks. （20점）
