Biology investigation --- the effect of cubes taken at different distance from the centre of the root on the percentage increase in mass

... James Fung 12thNovember,2002 Biology investigation --- the effect of cubes taken at different distance from the centre of the root on the percentage increase in mass Result Distance from the centre of the root /cm (x) Increased in mass / % 1 2 3 Average (y) 1 6.7 6.9 6.5 6.7 2 5.5 5.6 5.7 5.6 3 4.2 4.2 12.3 6.9 4 2.5 2.5 2.5 2.5 5 1.9 2.0 2.4 2.1 6 0.1 0.3 0.2 0.2 Fig.1 Analysis In analysis the result obtained, I have drawn out a graph, Fig.1, which show that the information that I got was almost a straight line. This implies that as the distance of cubes taken from the centre of the root increases, the percentage increased in mass decreases, by considering individual distance, a same sort of pattern appears. When those cubes are taken from 1 cm from the root, they have an average of 6.7% of increased in mass, those taken at 2 cm from the root increased by 5.6% while cubes taken at 4 cm from the centre of root have increased by 2.5% in mass. In order to understand what happened,
