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

examples of bryophytes plant kingdom biology

  1. Capsule

  2. Seta

  3. Foot

  4. Haustoria

Show answer
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

Show answer
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.

  4. Capsule

Show answer
Correct Option: A

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

examples of bryophytes plant kingdom biology

  1. Fern and Funaria

  2. Funaria and Ficus

  3. Ficus and Chlamydomonas

  4. Punica and Pinus

Show answer
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'

  1. Leaves

  2. Stem

  3. Apophysis

Show answer
Correct Option: D

The plant body of Funaria is

examples of bryophytes plant kingdom biology

  1. Sporophyte

  2. Gametophyte

  3. Predominantly sporophyte with independent gametophyte

  4. Predominantly gametophyte with dependent sporophyte

Show answer
Correct Option: D
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.

Funaria gametophyte is

examples of bryophytes plant kingdom biology

  1. Dioecious

  2. Heteroecious

  3. Autoecious

  4. Monoecious and autoecious

Show answer
Correct Option: D
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.
