Paragraph Test - 25

Answer the questions according to the reading passages.
Many flowering plants charm insect pollinators and gently direct them to their most fertile blossoms by changing the color of individual flowers from day to day. Through color cues, the plant signals to the insect that It would be better off visiting one flower on its bush than another. The particular color tells the pollinator that the flower is full of far more pollen then are neighboring blooms. That nectar-rich flower also happens to be fertile and ready to disperse its pollen or to receive pollen the insect has picked up from another flower. Plants do not have to spend precious resources maintaining reservoirs of nectar in all the flowers. Thus the color-coded communication system benefits both plant and insect.
