Ethics of the therapeutic use of stem cells from specially created embryos, from the umbilical cord blood of a newborn baby and from an adult’s own tissues.

Use of stem cells to treat Stargardt’s disease and one other named condition.

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

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

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

Describe That Differentiation involves the expressions of some genes and not others in a cell’s genome.

Describe Specialized tissues can develop by cell differentiation in multicellular organisms.

Multicellular organisms have properties that emerge due to the interaction of their cellular components.

Explain Cell Surface to volume is an important limitation to cell size.
