Morphological Innovation Drives Sperm Release in Bryophytes

Advanced Science
Plant movements for survival are nontrivial. Antheridia in the moss Physcomitrium patens (P. patens) use motion to eject sperm in the presence of water. However, the biological and mechanical mechanisms that actuate the process are unknown.
