2.1.6 Explain the importance of the surface area to volume ratio as a factor limiting cell size.

2.1.7 State that multicellular orgainsms show emergent properties

2.1.8 Explain that cells in multicelular organisms differentiate to carry out specialized functions by expressing some of their genes but not others.
