Many flowering plants woo insect pollinators and gently direct them to their most fertile blossoms by

changing the colour of individual flowers from day to day Through colour cues, the plant signals to the

insect that it would be better off visiting one flower on its bush than another The particular hue tells the

pollinator that the flower is full of far more pollen than are neighbouring blossoms 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 their flowers Thus, the colour-coded communication system benefits both plant and insect

For example, on the lantana plant, a flower starts out on the first day as yellow, when it is rich with pollen and nectar Influenced by an as-yet-unidentified environmental signal, the flower changes colour

by triggering the production of the pigment anthromyacin It turns orange on the second day and red on

the third By the third day, it has no pollen to offer insects and is no longer fertile On any given lantana bush, only 10 to 15 percent of blossoms are likely to be yellow and fertile But in tests measuring the responsiveness of butterflies, it was discovered that the insects visited the yellow flowers at least 100

times more than would be expected from haphazard visitation Experiments with paper flowers and

painted flowers demonstrated that the butterflies were responding to colour cues rather than, say, the scent of the nectar

In other types of plants, blossoms change from white to red, others from yellow to red, and so on These colour changes have been observed in some 74 families of plants

1 The first paragraph of the passage implies that insects benefit from the colour-coded

communication system because

A the colours hide them from predators

B they can gather pollen efficiently

C the bright colours attract fertile females

D other insect species cannot understand the code

2 The word woo in line 1 is closest in meaning to

3 The word it in line 3 refers to a(n)

4 the word Thus in line 7 is closest in meaning to which of the following?

5 Which of the following describes the sequence of colour changes that lantana blossoms undergo?

6 The word triggering in line 10 is closest in meaning to

7 The passage implies that insects would be most attracted to lantana blossoms

A on the first day that they blossom

B when they turn orange

C on the third day that they blossom

8 According to the passage, what is the purpose of the experiments involving paper flowers and painted flowers?

A To strengthen the idea that butterflies are attracted by the smell of flowers

B To prove that flowers do not always need pollen to reproduce

C To demonstrate how insects change colour depending on the type of flowers they visit

D To support the idea that insects respond to the changing colour of flowers

9 The word haphazard in line 14 is closest in meaning to which of the following?

10 According to the passage, in approximately how many families of plants has the colour changing phenomenon described in the passage been observed?
