Learning Intentions for Unit 2:

Multicellular Systems

1.1 Cells, Tissues and Organs

1.

Explain how cells become specialised.

2.

Understand how the specialisation of cells contributes to the variety of tissue types in a multicellular organism.

3.

State how the possible variety of tissue types contributes to the formation of different organs & organ systems.

1.2

Stem Cells and Meristems

1.

State that stem cells are non-specialised animal cells that can develop into any of the specialised body cells of that animal.

2.
