Answer:</h2>
The statement about the plant cycle is true.
<h2>
Explanation:</h2>
All plants experience an actual existence burn that takes them through both haploid and diploid ages. The multicellular diploid structure of plant is known as the sporophyte that produces spores through meiotic (agamic) division. The multicellular haploid structure of plant is known as the gametophyte, which is shaped from spore and offer ascent to haploid gametes.
The change between these haploid stage and diploid stage that happens in plants is known as the generations alternation. The manner by which the generations alternation happens in plants relies upon the kind of plant. In bryophytes (greeneries and liverworts), the predominant age is haploid, so the gametophyte includes what we consider as the primary plant.
The inverse is valid for tracheophytes (vascular plants), in which the diploid age is predominant and the sporophyte involves the primary plant.
The answer to this question is the Silurian strata. These are spores of the Psilophytes which appeared at the end of the Silurian period. The spores have been found in early Silurian rocks in Libya. Psilophytes did not have roots or leaves, but has branches carrying spore sacs that grew from an underground vine.
