Answer:
Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.
Explanation:
Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.

<u>EARTH'S MAGNETIC FIELD</u></h2>
The magnets point North when the Earth's magnetic field has?
<h2>
<u>ANSWER</u></h2>
I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
<h2>
<u>THE MAGNETIC REVERSAL</u></h2>
The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
