Question

Fern belongs to the subgroup
A) Bryophyta
B) Pteridophyta
C) Algae
D) Thallophyta

Answer 1

Hint: Ferns are seedless vascular plants of humid tropics and temperate areas. There are no waxes or special cells on the surface that block water from evaporating. They've got roots, branches, leaves.

Complete answer:
Generally, the ferns reproduce by producing spores. Different from flowering plants, the fountains have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they typically reproduce sexually through small spores or can reproduce vegetative propagation, as exemplified by a walking fern.

The ferns are seedless vascular plants in tropical tropics and temperate regions. Few ferns often survive under sub-arctic conditions. The fern belongs to a group of approximately species of vascular plants which can reproduce by spores who have neither seed nor flowers.

They differ from mosses in that they are vascular (i.e., having water-conducting vessels). They have roots and leaves, much like most vascular plants. Most of the ferns have fiddleheads that grow into fronds, each of which would be delicately separated. Leptosporangiate ferns tend to be the larger group, however, the ferns mentioned here include horsetails, whisk ferns, marattia ferns & ophioglossum ferns.

This group can be referred to as monophytes. Traditionally, the term pteridophyte refers to ferns and few other seedless vascular plants. There are no waxes or special cells on the surface that block water from evaporating. They've got roots, branches, leaves. Their stems can form runners, called stolons above the ground, or rhizomes below the ground.

The leaves are large and green and may have spores on the underside. There are ferns that can grow big in damp areas. They can live in more areas than most, but not as much as flowering plants.

Additional information:
A large number of ferns is in biological research, for they have retained a primitive life cycle involving two separate and more or less independent generations, or growth phases, the plants of which are wholly different in many aspects.

Ferns are not of great economic significance, but some have been used as food, drugs, biofertilizers, ornamental plants and soil remediation. They have been the focus of studies on their ability to eliminate certain organic compounds from the atmosphere.

In biological science, the major advantage of ferns is that they have maintained a primitive life-cycle spanning two distinct and more or less autonomous generations, or development stages, of which the plants are entirely different in certain respects.

Hence, the correct answer is an option (B) 'Pteridophyta'.

Note: A few hundred million years ago, ferns and fern associates were dominant terrestrial species. As a result, the remains of these plants have contributed substantially to the formation of our fossil fuels—coal, oil and natural gas.
