CSEC Biology · May/June 2010 · Paper 2 · Question 1(a)(i)

An experiment was conducted on a plant species (Figure 1) where part X was tested after plants grew in three different light intensities. Sets of three plants for each light intensity were tested for starch, reducing sugar, protein, and oil.

In the space provided below construct a table to show how the data from the experiment might be collected.

This question uses a figure or table from the paper — you'll see it when you practise.
