The cell wall provides a structured shape for the cell, helping the plant retain its form.

It also helps keep much of the internal functions of the cell, such as processing water inside of the plant.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
