Hornworts, mosses and liverworts do not have vascular tissue. They are considered in the division Byrophyta, none of which contain vascular tissue. Ferns are a step up in complexity in the division Pteridophyta, the first plants which contain vascular tissue. </span>
I would say that active transport is the answer because it's from LOW concentration to HIGH concentrations, so it's going against the concentration gradients.
