Plant Biology and Classification

The sporophyte of a typical moss (such as Funaria) consists of a foot, seta, and capsule containing a central sterile columella, but it completely lacks elaters. Elaters are specialized, hygroscopic cells found in the sporophytes of some liverworts (like Marchantia) that aid in spore dispersal.

Apophysis is the sterile basal region of the capsule in the sporophyte of mosses. It contains stomata and chloroplasts, allowing it to perform photosynthesis.

Anthoceros, a hornwort, contains mucilage cavities in its thallus that are colonized by the nitrogen-fixing cyanobacterium Nostoc. This forms a symbiotic relationship that assists the plant with nitrogen nutrition.

Bog moss is the common name for Sphagnum, which belongs to the class Bryopsida (true mosses). Reindeer moss is actually a lichen, club moss is a pteridophyte, and Irish moss is a red alga.

Sphagnum belongs to the class Bryopsida of the division Bryophyta, which comprises the true mosses.

Anthoceros belongs to the class Anthocerotopsida (hornworts), not Bryopsida (which contains true mosses like Funaria and Sphagnum). Therefore, Bryopsida - Anthoceros is the incorrect pair.

Pteris is a pteridophyte (fern), whereas Pellia, Porella, and Funaria are all bryophytes.

Polytrichum is a bryophyte (moss), whereas Selaginella, Equisetum, and Salvinia are all pteridophytes.

Mosses (bryophytes) are traditionally called the amphibians of the plant kingdom because they live on land but require water for sexual reproduction. While ferns are pteridophytes, this description is the best fit among the options.

The majority of liverworts (Hepaticae) have a dorsiventrally flattened, thalloid plant body (such as Marchantia and Riccia), although some leafy (foliose) forms also exist.

Sphagnum is known as peat moss because its accumulation over time in acidic, waterlogged conditions forms peat, which is used as fuel and organic matter.

Statement (a) is incorrect because the sporophyte of mosses is more elaborate than that of liverworts. Statement (d) is incorrect because Pinus is monoecious, meaning male and female cones are borne on the same tree.

Mosses require water for fertilization so that the biflagellate antherozoids can swim to the archegonium to fertilize the single egg. Their sporophyte is dependent on the gametophyte, and archegonia produce only a single egg.

Sphagnum is the scientific name of peat moss. It is a moss. It is also called as bog moss. It has high pH. Hence, it is used for plants growing in acidic condition, such as blueberries. It helps in moisture absorption from the soil.

Sewardiella tuberifera is a rare, monotypic liverwort endemic to India, discovered in the Western Himalayas (Shimla, Mussoorie) by the Indian botanist Shiv Ram Kashyap.
