he fruit of the mistletoe, a parasitic angiosperm, is a one-seeded berry. In members of the genus Viscum, the outside of the seed is viscous (sticky), which permits the seed to adhere to surfaces, such as the branches of host plants or the beaks of birds. What should be expected of the pericarp if the viscosity of Viscum seeds is primarily an adaptation for dispersal rather than an adaptation for infecting host plant tissues?
For the following questions, match the adaptations of the various fruits below with the most likely means used by the fruit to disperse the seeds contained within the fruit (A-E).
A. animal skin, fur, or feathers
B. animal digestive tract
C. water currents
D. gravity and terrain
E. air currents
