Lignin is a biopolymer that gives support to vascular plants, and is thought to have evolved after aquatic plants took on land. many aquatic plants produce lignin or lignin-like polyphenols however. There is still debate on distinguishing terrestrial from aquatic plant lignin.
nonvascular
Vascular tissue is the tissue which makes steam strong . As their are no such tissue in steam of aquatic plant it makes them weak.
In aquatic environments (oceans, lakes, rivers), algae are dominant over vascular plants; but vascular plants do exist in those places. There are also places on land where nonvascular plants -- mosses, liverworts, and hornworts -- are dominant over vascular plants: they tend to be very, very moist and/or lack enough soil for anything larger to get a foothold.
