for growth and repair. This gains them two points towards Achievement. Candidate
also identifies that cell type contributes to why the cell divides. This third point earns
them an A3 for this question, as their description of DNA replication is incomplete.
One Achievement point is awarded for the description of light as a factor that affects
photosynthesis. No clearly correct equation is provided, and the way that H20 and
CO2 affect photosynthesis is not described. N1 grade awarded.
Candidate links mitosis to respiration and energy in order to get an Achievement
point. The link between mitochondria number and energy demand is also made,
therefore N2 is awarded. The statements around each cell type only provide
examples to illustrate the candidate’s second point. N2 is awarded.
