Question:

Which of the following statement is wrong about bryophytes?

Options:

Bryophytes are also called amphibians of the plant kingdom.

Bryophytes play an important role in plant succession on bare rocks/soil.

They have true roots, stems or leaves.

The sex organs in bryophytes are multicellular.

Correct Answer:

They have true roots, stems or leaves.

Explanation:

The correct answer is Option (3) -They have true roots, stems or leaves.

Bryophytes are also called amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. They usually occur in damp, humid, and shaded localities. They play an important role in plant succession on bare rocks/soil. The plant body of bryophytes is more differentiated than that of algae. It is thallus-like and prostrate or erect and attached to the substratum by unicellular or multicellular rhizoids. They lack true roots, stem,s or leaves. They may possess root-like, leaf-like, or stem-like structures. The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte. The sex organs in bryophytes are multicellular. The male sex organ is called the antheridium. They produce biflagellate antherozoids. The female sex organ called archegonium is flask-shaped and produces a single egg.
