In which of the features do bryophytes differ from pteridophytes?

Bryophytes differ from pteridophytes in their dependency on water for reproduction. Bryophytes, which include mosses and liverworts, are small, non-vascular plants that require water for the sperm to swim to the egg. Pteridophytes, which include ferns and horsetails, have a vascular system that allows them to transport water and nutrients and do not require water for the sperm to swim to the egg. Other options are not the distinguishing features between bryophytes and pteridophytes.
