<span>Bryophytes</span> are more adapted for moist environments. This is due to the fact that they can live in water-filled places with mild temperatures.
Auxin is used to stimulate plant growth which occurs at the roots and shoots of plants. you must have heard that plant growth is apical therefore it helps for apical dominance. <span>Apical dominance is the phenomenon whereby the main, central stem of the plant is dominant over (i.e., grows more strongly than) other side stems; on a branch the main stem of the branch is further dominant over its own side branchlets that is the shoot has more control over the lateral bud growth.</span>
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
