Learner Target
Activity
Evidence
State the importance of the cell wall
and cell membrane and describe
their structure and function. Include
a discussion of the hydrophobic and
hydrophilic properties of bilayer.
Explain how substances cross the
cell membrane including simple
diffusion, osmosis, facilitated
diffusion, active transport,
endocytosis and exocytosis.
Understand the reasons for limited
cell size and how surface area and
volume compare to each other
Explain how enzymes govern the
rates of cell reactions and how they
work
