• A. Bryophyta
• B. Pteridophyta
• C. Gymnosperm
• D. Angiosperm

Answer 1

The correct option is B

Pteridophyta

The correct option is B.

Explanation of the correct option:

1. Pteridophytes are the first vascular plants having xylem and phloem.
2. They have true differentiation of leaves (fronds), roots, and stems.
3. The plant body of the ferns belonging to the division of Pteridophyta is differentiated to form roots, stems, and leaves.
4. The ferns have a well-developed vascular system (xylem and phloem) for the conduction of water and other substances.
5. This plant also shows the presence of sporophylls containing spores on the underside of the leaves.
6. the plant's body contains multicellular sex organs and is jacketed by sterile cells.

Explanation of the incorrect options:

Option A:

Bryophytes are the simplest forms of land plants. The plant body is flat and lacks true leaves and roots.

Option C:

Gymnosperms are intermediate between cryptogams and angiosperms. They have well-developed reproductive organs.

Option D:

1. Angiosperm constitutes the largest group of plants. Seeds are produced inside an ovary which later becomes the fruit.
2. These are highly evolved groups of plants. The plant body is distinctly differentiated into roots, stems, and leaves.

Final answer: Ferns are a type of Pteridophyta.
