Answer:
(E) seedless vascular plant
Explanation:
Seedless vascular plants, compared to some other kinds of plants, reproduce and disperse through unicellular spores instead of seed. They possess vascular tissues but do not possess seed or flower.
The life cycle of the seedless vascular plant is characterized by alternation between the diploid sporophyte and haploid gametophyte. The haploid gametophyte is small, but still independent while the diploid sporophyte is is large and long- lived, it is the dominant phase of the life cycle.
Examples of seedless vascular plants are horsetails and ferns
