Multiple choice examples of bryophytes plant kingdom biology

Which is not correct about Funaria?

  1. Sporophyte is semiparasite on gametophyte

  2. Spores are produced by outer endothecial cells

  3. The spore germinates to produce primary protonema

  4. There are two neck canal cells in archegonia

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In Funaria archegonia, there are multiple neck canal cells, not just two. The other statements correctly describe the sporophyte's semi-parasitic nature, the endothecial origin of spores, and the protonema stage.

Identify wrong statement in relation to Funaria.

  1. Stomata are present in the epidermis of capsule

  2. Spores are viable for only one year

  3. Inner spore sac is one celled in thickness

  4. Trabeculae connect the innermost layer of the capsule wall with outer spore sac

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The spores of Funaria are generally viable for a longer period than one year. The other statements regarding stomata in the capsule epidermis, the thickness of the spore sac, and the presence of trabeculae are correct.

Primary protonema is present in

  1. Agaricus

  2. Alternaria

  3. Sphagnum

  4. Funaria

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The primary protonema is a characteristic juvenile stage in the life cycle of mosses, such as Funaria. It develops directly from the germinating spore.

Funaria is

  1. Heteroecious

  2. Dioecious

  3. Monoecious

  4. Trioecious

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Funaria is monoecious, meaning both male (antheridia) and female (archegonia) sex organs are produced on the same plant body, though often on different branches.

Multiple choice examples of bryophytes plant kingdom biology

Which amongst the following 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

Ferns (pteridophytes) and Funaria (bryophytes) reproduce via spores rather than seeds. Ficus, Punica, and Pinus are seed-producing plants (spermatophytes).

Multiple choice examples of bryophytes plant kingdom biology

Plant body of Funaria is

  1. Completely sporophyte

  2. Completely gametophyte

  3. Predominantly sporophyte with gametophyte

  4. Predominantly gametophyte with sporophyte

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In bryophytes like Funaria, the gametophyte is the dominant, independent, and photosynthetic phase. The sporophyte is dependent on the gametophyte for nutrition.

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

Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Multiple choice examples of bryophytes plant kingdom biology

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

Reveal answer Fill a bubble to check yourself
D Correct answer
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

Reveal answer Fill a bubble to check yourself
B Correct answer
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.
