PROBLEM: Person1: I watched a very interesting documentary about plants yesterday evening . It was called " unusual plants " and looked at several species of plants from around the world which have unusual features .
Person2: Really ? Tell me about some of the plants they showed .
Person1: Well . There was one type of plant that catches insects and eats them .
Person2: Is that type of plant found in this country ?
Person1: No , it isn ' t . it ' s a pity , because I ' d like to see it in action .
Person2: So would I . what other unusual plants did they show ?
Person1: They showed flowers that only provide their nectar to one type of butterfly or bee . The insect has to be the exact size to get the nectar . Other insects cannot get it . Of course , when the insect collects the nectar , it also takes some pollen from one flower to another .
Person2: That ' s very specialized . So , the insects and the flowers rely on each other . If one became extinct , the other would too .
Person1: That ' s right . That ' s one reason why it ' s so important to protect every species .
Person2: I see . The plants that fascinate me most are cacti . I find it amazing that they can survive in such dry desert conditions .
Person1: According to the documentary , they have an incredible ability to find water supplies , however small , and then store them without losing much through evaporation .
Person2: That ' s why they often have long roots to find water spines instead of leaves , to reduce water loss .
