Suppose a moss species evolved an efficient conducting system allowing it to grow as tall as a tree. Which of the following statements about such a 'tree' would most likely be true without further adaptations?

  • A: Spore dispersal distances would probably decrease.
  • 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 less effectively for access to light.

Explanation

Even with an efficient conducting system, a tall plant requires significant structural support to resist gravity and wind. Mosses, in their natural form, lack such robust structural tissues. Therefore, a moss growing to tree-like heights would collapse without additional adaptations for strength, such as extensive lignin or woody tissues.
