(a) Draw a line graph of the height of the plant with time.
Use the vertical axis (Y) as the height and the horizontal
axis (X) as time. Label the graph.
(b) Now draw a second graph of the number of leaves with
time. Use the vertical axis (Y) as the number of leaves and
the horizontal axis (X) as time. Label your graph.
Conclusion
From graph (a) : Does the seedling grow at a steady rate?
