Directions: Read the passage and answer the question.

When a bee, or an ant, beetle, moth or butterfly visits a flower for food, it simultaneously, and without knowing it, performs another vital function by carrying pollen from one plant to another. But not all flowers are visited by insects. A reliable guide to those that are, is their flamboyance. If the petals are large and colourful, if they smell sweet, it is because the plant needs to attract insects. Some plants have flowers which are graceful but not showy and therefore of no interest to insects. In this case the pollen is carried by the wind. Most flowers manufacture these minute grains called pollen which must be transferred to another flower of the same type before they can make seeds.
