Two students suggested that the wallflower cannot produce fruit unless pollination has taken place. Their teacher showed them how to prevent bees reaching the flowers by covering the flowers by covering the flowers in a fine paintbrush.

a) describe how the students could carry out an experiment to test their hypothesis

b) suggest how they could modify their experiment to test whether self or cross pollination produced more seeds in the wallflower.

In your answer be sure to describe any controls which they could include, and any steps they could take to ensure that their results were valid.
