1.1.U1
According to the cell theory, living organisms are composed of cells.

1.1.U2
Organisms consisting of only one cell carry out all functions of life in that cell.

1.1.U3
Surface area to volume ratio is important in the limitation of cell size.

1.1.U4
Multicellular organisms have properties that emerge from the interaction of their cellular components.

Synergy
Emergent properties

1.1.U5
Specialized tissues can develop by cell differentiation in multicellular organisms.

1.1.U6
Differentiation involves the expression of some genes and not others in the cell's genome.

1.1.U7
The capacity of stem cells to divide and differentiate along different pathways is necessary in embryonic development. It also makes stem cells suitable for therapeutic uses.

1.1 A1
Questioning the cell theory using atypical examples, including striated muscles, giant algae and aseptate fungal hyphae.

1.1 A2: Paramecium
Investigation of functions of life in Paramecium and one named photosynthetic unicellular organism.

1.1 A2: Chlorella
Investigation of functions of life in Paramecium and one named photosynthetic unicellular organism.

1.1 A3: Stargardt's
Use of stem cells to treat Stargardt's disease and one other named condition.

1.1 A3: Leukemia
Use of stem cells to treat Stargardt's disease and one other named condition. See Google Doc Assignment "Use of Stem Cells to treat Stargardt's"

1.1 A4
Ethics of therapeutic use of stem cells from specially created embryos, from the umbilical blood in a new born baby, and adult tissue. See Google Doc Assignment "Ethics of Using Stem Cell Therapy"
