Ferns are seedless plants that developed around 75 million years after the emergence of the first land plants. Despite the seedless structure, these plants have developed vascular systems with sporophytes that were nutritionally independent from gametophytes. However, the first fern plants only grew to less than 20cm in height.
Which of the following applies to a 15 meter tall tree fern?
A. a gametophyte
