Question #47540
The Question
A population of bryophytes is subjected to intense herbivory targeting its dominant photosynthetic phase. To escape local extinction, the population relies on its 'r-selected' ecological strategy and specific anatomical adaptations for dispersal to new niches. Which of the following statements regarding this survival mechanism is INCORRECT?
Options
- A.
The elaborate hygroscopic peristome teeth in mosses regulate the gradual release of spores, optimizing wind dispersal to predator-free niches.
- B.
The structures facilitating this dispersal are anatomically part of the diploid sporophyte, which is nutritionally dependent on the grazed phase.
- C.
To maximize colonization success, the sporophyte produces a massive number of diploid spores via mitosis, characteristic of an r-selected species.
- D.
In liverworts such as Marchantia, diploid elaters present in the capsule assist in the dehiscence and scattering of haploid spores.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: The trap exploits the intersection of Ecology and Plant Anatomy.
Students easily recognize the 'r-selected' trait of producing massive numbers of offspring (spores) but often overlook the fundamental botanical rule of 'sporic meiosis' in plants.
The distractor seamlessly blends a correct ecological concept (high fecundity for colonization) with a fatal anatomical error (diploid spores via mitosis instead of haploid spores via meiosis).
