The 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 fruit if the viscosity of Viscum seeds is primarily an adaptation for dispersal rather than an adaptation for infecting host plant tissues?
A) It should be drab in color.
B) It should be colored so as to provide it with camouflage.
C) It should be nutritious.
D) It should secrete enzymes that can digest bark.
E) It should contain chemicals that cause birds to fly to the ground and vomit.
This bleeding heart plant (the genus Dicentra) is an example of an angiosperm.
