Solution

The correct answer is "The sperm must swim to the egg."

In liverworts, a type of bryophyte, asexual reproduction is dependent on water because the male gametes (sperm) need a film of water to swim through to reach the female gametes (eggs). This is a common feature in many non-vascular plants. The sperm is produced in antheridia and the eggs in archegonia. When water is present, the antheridia release the sperm, which swim to the archegonia to fertilize the eggs. This process is dependent on water.
