<p><span style="font-size: 16px;">Mosses and their relatives are <span style="background-color: #ccffff;">seedless nonvascular plants, <span style="background-color: #ffffff;">they are called</span> bryophytes</span>. They lack a vascular system (plumbing system) to move water and nutrients throughout the plant. For this reason, they grow close to the ground to absorb water and nutrients. </span></p>
<p><span style="font-size: 16px;">Seedless plants also rely on free-standing water for reproduction. A sperm produced by a male must swim through rainwater or dew to reach an egg. The diploid the undergoes meiosis to produce haploid spores. These spores may also need moisture to disperse.&nbsp;</span></p>
