The first vascular plant appeared around 410 million years ago based according to the fossil records.
The plants had little spore cases at the tips of the plant called sporangia.
The nutrition of vascular plants is photosynthesis. Photosynthesis is the process of converting light energy into chemical energy and storing it in the bonds of sugars.
this process takes place in the chloroplasts, specifically using chlorophyll. Plants only need light energy, CO2, and H2O to make sugar.
Larger in size!
can absorb water better
So in the end, vascular plants are more practical and obviously better than non vascular plants.
