Chapter 29, Problem 5TYU
Suppose an efficient conducting system evolved in a moss that could transport water and other materials as high as a tall tree. Which of the following statements about “trees” of such a species would not be true?
(A) Spore dispersal distances would probably increase.
(B) Females could produce only one archegonium.
(C) Unless its body parts were strengthened, such a“tree” would probably flop over.
(D) Individuals would probably compete more effectively for access to light.

Suppose an efficient conducting system evolved in a moss thatcould transport water and other materials as high as a tall tree.Which of the following statements about “trees” of such aspecies would not be true?(A) Spore dispersal distances would probably increase.(B) Females could produce only one archegonium.(C) Unless its body parts were strengthened, such a “tree”would probably flop over.(D) Individuals would probably compete more effectively foraccess to light.
Which of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.
Read these two statements about plant-fungal interactions, then pick the statement below that is TRUE.
(A) Root fungi in phylum Ascomycota can cause plants to produce antioxidants that provide protection against the stress of drought, and plants feed carbon to
the fungi in their roots.
(B) Root fungi and plants have evolved mutual benefits through a long history of interaction, in which fungi that provided the greatest benefits to plants had the
highest fitness because of the carbon the plants fed them, and plants that supported fungi had the highest fitness because of the protection provided by the
fungi.
(A) is a proximate cause for plant-fungal symbiosis, whereas (B) is an ultimate cause.
O (A) is an ultimate cause for plant-fungal symbiosis, whereas (B) is a proximate cause.
Understanding plant-fungal interactions would NOT require cost-benefit analysis because there are no fitness trade-offs.
(A) is an innate behavior and (B) is a learned behavior.
