2.1.2 Discuss the evidence for the cell theory

2.1.3 State how unicellular orgaisms carry out all the functions of life

2.1.4 Compare the relative sizes of molecules, cell membrane thickness, viruses, bacteria, organelles and cells, using the appropriate SI unit

2.1.5 Calculate the linear magnification of drawings and the actual size of speciemenes in images of known magnification.

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.

2.1.9 State that stem cells retain the capacity to divide and have the ability to differentiate along different pathways.
