Plant body of Funaria is

  1. Completely sporophyte

  2. Completely gametophyte

  3. Predominantly sporophyte with gametophyte

  4. Predominantly gametophyte with sporophyte


Correct Option: D

Gemmae are the specialized structures produced in liverworts. These are ____________________.

  1. non-green, multicellular, asexual buds which develop in gemma cups

  2. green, multicellular asexual buds which develop in gemma cups

  3. non-green, multicellular, diploid, sexual spores

  4. green, unicellular, diploid, sexual spores


Correct Option: B
Explanation:

Gemmae are green multicellular asexual buds, which develop in small receptacles called gemma cups located on the thalli. Gemmae become detached from the parent body and germinate to form new individuals.

So the correct option is B.

The sporophytic phase in Funaria is well developed and composed of ________________.

  1. Capsule only

  2. Spore sac

  3. Foot and capsule

  4. Foot, seta and capsule


Correct Option: D
Explanation:

Sporophyte of Funaria has embedded foot, an elongated curved seta and a terminal pyriforrn capsule. Sporophyte is nutritionally dependent on gametophyte.

So the correct option is D.

Gemmae are multicellular green structures for vegetative propagation. These are found inside gemma cups in _________________.

  1. Riccia capsule

  2. Marchantia thallus

  3. Funaria protonema

  4. Polytrichum thallus


Correct Option: B
Explanation:

In Marchantia, the plant body consists of a dorsoventrally flattened, prostrate and dichotomously branched thallus. The thalli are conspicuous, the apex of each thallus is notched. Along the mid-rib are present characteristic, prominent goblet or cup-shaped structures, the gemma cups, with smooth, dentate or frilled margins. These cups enclose asexual reproductive bodies called gemma.So the correct option is B.
