In which of the following bryophyta, germination of spore is indirect?

  1. Riccia

  2. Rhizopus

  3. Puccinia

  4. Funaria

D Correct answer
Explanation

In Funaria, the spore germinates to form a protonema (a filamentous structure) before developing into the leafy gametophore, which is considered indirect germination.

  1. Foot

  2. Calyptra

  3. Ventral canal cell

  4. Protonema

D Correct answer
Explanation

Funaria (a moss) produces a protonema stage in its life cycle, whereas Marchantia (a liverwort) does not.

The sporophyte of moss absorbs water from gametophyte with the help of

  1. Capsule

  2. Seta

  3. Foot

  4. Haustoria
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sporophyte of moss differentiates into foot, seta and capsule. The foot embedded in the female receptacle and absorbs inorganic nutrients. Seta is a long stalk with a pear-shaped capsule by its tip. Capsule has 3 parts-basal apophysis, central theca and terminal operculum.

Which of the following is example of moss?

  1. Funaria

  2. Riccia

  3. Anthoceros

  4. Pellia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Funaria is a genus of mosses in which the leaves are often crowded towards the tops of short stems. The leaves are tongue-shaped to ovate. The capsule is pyriform. The capsules are often numerous and are initially green and pear-shaped, becoming yellowish to orange-brown when ripe; they are borne on long, usually curved setae.
Riccia and Pellia belongs to the class Hepaticae. Anthoceros belong to the class Anthocerotae. 
Therefore, the correct answer is option A.
Multiple choice examples of bryophytes plant kingdom biology

Sporophyte of Funaria begins development inside

  1. Archegonium

  2. Antheridium

  3. Protonema

  4. Capsule
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The zygote, which develops into the sporophyte, is formed and begins its development within the venter of the archegonium.

Multiple choice examples of bryophytes plant kingdom biology

Which one of the following pairs of plants are not seed producers?

  1. Fern and Funaria

  2. Funaria and Ficus

  3. Ficus and Chlamydomonas

  4. Punica and Pinus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A- Funaria and Ferns do not bear flowers and therefore they do not bear seeds. The spores function much like seeds which are produced in special structures called sporangia or special cup shaped structures called sori.
So, the correct answer is 'Fern and Funaria'
Multiple choice examples of bryophytes plant kingdom biology

Funaria differs from Pteridium in the  absence of ___________.

  1. Root

  2. Stem

  3. Archegonia

  4. Embryo
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Funaria is a bryophyte and lacks true vascular tissues, including true roots, stems, and leaves. Pteridium is a pteridophyte and possesses true roots.

Multiple choice examples of bryophytes plant kingdom biology

In Funaria, stomata occur over __________.

  1. Leaves

  2. Stem

  3. Apophysis

  4. Capsule
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The capsule of the Funaria sporophyte contains an apophysis region which possesses stomata for gas exchange.

Multiple choice examples of bryophytes plant kingdom biology

The plant body of Funaria is

  1. Sporophyte

  2. Gametophyte

  3. Predominantly sporophyte with independent gametophyte

  4. Predominantly gametophyte with dependent sporophyte
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the life cycle of Funaria, two distinct individuals occur. One of these is haploid and is the independent leafy plant. The other is diploid, leafless sporogonium. It is partially dependent on the leafy gametophyte for its nutrition.

Multiple choice examples of bryophytes plant kingdom biology

Funaria gametophyte is

  1. Dioecious

  2. Heteroecious

  3. Autoecious

  4. Monoecious and autoecious
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Funaria is both monoecious and autoecious. The antheridium (male sex organ) are born on different heads of the same plant. Hence, it is both autoecious and monoecious.
