Examiners report

This question was derived from the skill of drawing half-views of animal pollinated flowers and the understanding of mutualistic relationships involved in plant reproduction. A large number could identify the ovule, but many incorrect answers, such as ovary, were also seen, as well as totally irrelevant answers.
