Questions Related to examples of bryophytes

Leafy gametophyte occur in

  1. Liver worts

  2. Horn worts

  3. Moss

  4. Fern


Correct Option: C
Explanation:

Moss gametophytes are either erect or extensively branched prostrate plants, that consist of an axis (commonly called a stem) bearing spirally arranged leaf-like appendages (usually referred to as leaves); more often than not, they are anchored to the substratum by branched multicellular filaments called rhizoids. The leafy shoot of mosses is haploid and thus part of the gametophyte generation. Liverworts and Hornworts have dorsiventrally flattened plant body. 

Which of the following plants do not produce seeds?

  1. Ficus and Funaria

  2. Fern and Funaria

  3. Chlamydomonas and Ficus

  4. Punica and Pinus


Correct Option: B
Explanation:

Ferns and moss are both examples of primitive plants. They are flowerless or seedless plants. Fern and Funaria both are flowerless and seedless.

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

  1. Riccia

  2. Rhizopus

  3. Puccinia

  4. Funaria


Correct Option: D

Funaria differs from Marchantia in having __________.

  1. Foot

  2. Calyptra

  3. Ventral canal cell

  4. Protonema


Correct Option: D

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

  1. Capsule

  2. Seta

  3. Foot

  4. Haustoria


Correct Option: C
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


Correct Option: A
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.

Sporophyte of Funaria begins development inside

  1. Archegonium

  2. Antheridium

  3. Protonema

  4. Capsule


Correct Option: A

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


Correct Option: A
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'

Funaria differs from Pteridium in the  absence of ___________.

  1. Root

  2. Stem

  3. Archegonia

  4. Embryo


Correct Option: A

In Funaria, stomata occur over __________.

  1. Leaves

  2. Stem

  3. Apophysis

  4. Capsule


Correct Option: D
