Which quantities go on the axes of a graph showing how a factor affects photosynthesis rate?
Put the factor on the horizontal axis and photosynthesis rate on the vertical axis. Label both axes with quantities and units.
How should scales be chosen for a photosynthesis rate graph?
Choose scales that cover the data and use the available space appropriately.
How should tabulated values be represented on a photosynthesis rate graph?
Plot the numerical values accurately as points, then draw an appropriate line or curve to show the pattern.
How can you find the numerical values represented by a point on a photosynthesis rate graph?
Read the point’s values from the axis scales.
What changes in rate should you look for when interpreting a photosynthesis rate graph?
Identify where the rate rises, levels off or falls as the factor changes.
What might a plateau on a photosynthesis rate graph indicate?
Another factor may be limiting, so further increases in the plotted factor do not increase the rate.
