Biology · PLANT KINGDOM

हिन्दी

Bryophytes are referred to as the 'amphibians of the plant kingdom' because:

They live in soil but are dependent on water for sexual reproduction as flagellated male gametes swim to female sex organs.
They live exclusively in aquatic ecosystems and lack photosynthetic pigments.
Their sporophytic generation is aquatic while their gametophytic generation is terrestrial.
They possess true vascular tissues (xylem and phloem) that require water for transport.

Correct answer · Option 1

They live in soil but are dependent on water for sexual reproduction as flagellated male gametes swim to female sex organs.

Explanation

Bryophytes can live in moist soil but require external film of water for flagellated antherozoids to swim towards archegonia during fertilization.
