Which of the following is the unique feature of bryophytes?

Step-by-step solution

They are the simplest and most primitive land plants and they require water to complete their life cycle. They are also known by the name of amphibians of the plant kingdom and are found in moist and shady places. They possess rhizoids to absorb water from the soil. The gametophytic generation in bryophytes is long-lived while sporophytic generation is short-lived so the sporophyte is completely dependent on the gametophyte for nutrition. Vascular tissue is completely absent in Bryophytes.
