Although the radish seed used in the experiment are products of sexual reproduction, they show little genetic diversity. List one or two uses of each of these elements in plants. Refer to your textbook to find out what plants may look like if lacking one of these elements. Note the expected symptoms of deficiency for each element and compare these with the radishes grown with no fertiliser pellets. If the graph is not a straight line how can you tell at which level the nutrients are being used most efficiently.
L is a good plant for such studies.
