Question

are nutrients in liverworts absorbed from soil via the rhizoids?

Answer 1

or do the rhizoids serve some other purpose?

Answer 2

A rhizoid is a root like structure (not actual roots however) things like water and mineral salts are absorbed over the entire structure courtesy of the rhizoid. I'd say yes they do, as liverworts possess multi-celluar rhizoids

Answer 3
