Which one of the following organisms is a bryophyte?
1 Liverwort
2 Volvox
3 Chlamydomonas
4 Fern
Explanation:
Bryophytes is the informal group name for liverworts, mosses, and hornworts. They are nonvascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through surface.

Female reproductive organ of Riccia is known as:
1 Oedogonium
2 Archegonium
3 Carpogonium
4 Oosphere
Explanation:
In Bryophytes (like Riccia, Funaria etc.) dominant generation is gametophyte which is freeliving, haploid and photosynthetic. In gametophytes, sex organs antheridium and archegonium are present from which antherozoid and egg are produced respectively. In Riccia, the antheridia and archegonia are scattererd and found embedded in the dorsal side of thallus.

Life cycle of Funaria is not completed without water. Choose the correct statement.
1 As Funaria is a bryophyte plant
2 As branches will not develop
3 As fertilization takes place in presence of water only
4 As plant is delicate and will become dry and die without water
Explanation:
The life cycle of Funaria is not completed without water because fertilization takes place in the presence of water only. Bryophytes are terrestrial, nonvascular plants (absence of xylem and phloem) that still require a moist environment to complete their life cycle.

Apophysis in the capsule of Funaria is
1 lower part
2 upper part
3 middle part
4 fertile part
Explanation:
Apophysis is the lower, solid, sterile portion of the capsule that contains a chloroplast and is sterile. The focal piece of the apophysis is comprised of extended flimsy walled cells forming a conducting strand.

In a moss the sporophyte-
1 is partially parasitic on the gametophyte.
2 produces gametes that given rise to the gametophyte.
3 Arises from a spore produced from the gametophyte.
4 Manufactures food for itself, as well as for the gametophyte.
Explanation:
Mosses, like funaria, are bryophytes. They are non-vascular plants. The main plant body is gametophytic (haploid) which is independent and foliose. It is a major part of the life cycle. The saprophytic phase starts with the zygote, which divides to form sporogenous tissue that is differentiated into foot, seta and capsule. The saprophytic phase is short lived. The foot absorbs nutrients and provides support to the sporophyte.
