Bryophytes resemble algae in the following aspects
1 filamentous body, presence of vascular tissues and autotrophic nutrition
2 differentiation of plant body into root, stem and leaves and autotrophic nutrition
3 thallus like plant body, presence of root and autotrophic nutrition
4 thallus like plant body, lack of vascular tissues and autotrophic nutrition
Explanation:
(d)Bryophytes have thallus like body and lack vascular tissue.

You are given an unknown plant to study in the laboratory. You find that it has chlorophyll, no xylem. Its multicellullar sex organs are enclosed in a layer of jacket cells. Its gametophyte stage is free living. The plant probably belongs to
1 Chlorophyceae
2 bryophyte
3 pteridophyte
4 gymnosperm
Explanation:
(b)According to the features described; the unknown plant belongs to bryophytes. Bryophytes refer to a group of plants comprising the mosses, liverworts, and hornworts. They do not have a true vascular system and are unable to pull water and nutrients up from the ground at any significant distance. This distinguishes bryophytes from ferns and flowering plants.

Moss peat is used as a packing materialfor sending flowers and live plants to distant places because
1 it reduces transpiration.
2 it serves as a disinfectant.
3 it is easily available.
4 it is hygroscopic
Explanation:
(d)Species of Sphagnum, a moss, provides peat that have long been used as a packing material for sending flowers and live plants to distant places because it is hygroscopic.

The unique feature of bryophytes compared to other plant groups is that
1 they produce spores.
2 they lack vascular tissues.
3 they lack roots.
4 their sporophyte is attached to the gametophyte.
Explanation:
(d)In bryophytes, zygotes donot undergo reduction division immediately. They produce a multicellular body called a sporophyte. The sporophyte is not a free-living but attached to the photosynthetic gametophyte and derives nourishment from it.
