In both groups, sperm swim from antheridia to archegonia
Explanation:
Bryophytes are the plant group that does not have a vascular system. These plants do not produce seeds. Ferns and horsetails are seedless vascular plants. These plants have vascular tissues (xylem and phloem) to serve in the conduction of water, minerals, and sugars from the one plant part to the other. But these plants do not produce seeds and hence, are seedless vascular plants.
Both bryophytes and the seedless vascular plants depend on water for fertilization. These plants release their male gametes in water which in turn move towards the female gamete. Sperms, the male gametes of these plants swim in the water to reach the female gamete.
Antheridium is the male gametangium that serves as a site for the production of male gametes while archegonia are the female gametangia where the egg cell is produced.
