_____________ are the amphibians of the plant kingdom.

Correct option is D

The correct answer is (d) Bryophyta

Bryophytes are called the "amphibians of the plant kingdom" because they require water for reproduction and spore dispersal. They thrive in moist environments, similar to how amphibians live both in water and on land. Bryophytes include mosses, liverworts, and hornworts.

They lack vascular tissues (xylem and phloem), so they absorb water directly from their surroundings, making them dependent on wet habitats.

Information Booster:

• Bryophytes are non-vascular plants, meaning they do not have a transport system for water and nutrients.
• They reproduce via spores, not seeds.
• They play a crucial role in soil formation and preventing erosion.
• Examples: Marchantia (liverwort), Funaria (moss), Anthoceros (hornwort).
• They serve as pioneer species in ecological succession.

Additional Information:

• Gymnosperms – Seed-producing plants with naked seeds (e.g., pine, cycas).
• Pteridophytes – First vascular plants, reproducing via spores (e.g., ferns, horsetails).
• Thallophytes – Simple, undifferentiated plants like algae that lack roots, stems, and leaves.
