Diversity in Living Organisms

Funaria (a moss) produces a protonema stage in its life cycle, whereas Marchantia (a liverwort) does not.

In moss, when the mature capsule begins to dry up, the thin walled cells of the annulus break and the operculum is thrown away. Dropping off the operculum is assisted by the outward hygroscopic movement of the underlying peristomial teeth. Due to this movement, slits between the inner thin walled peristomial teeth become wider and spores escape gradually through these slits. In a wet atmosphere, the wet peristomial teeth bend inwards and thus closing the slits and prevent the escape of spores. The seta of the mature sporophyte also exhibits hygroscopic movements. In dry weather, by loosing water, it twists and bents, thus helping in dispersal of spores. The sporogonium of Funaria is photosynthetic, hence semi-parasitic on gametophore. It differentiates into foot, seta and capsule. The foot embedded in the female receptacle and absorbs inorganic nutrients.

In Funaria, the androcyte mother cells divide diagonally and each forms two androcytes. The latter differentiate into biflagellate antherozoids. 

Rhizoids are branched, slender and multicellular. They are stout, brown, almost cable like and form the main anchoring strands. The rhizoids are colourless in the young stage, but become red or brown at maturity. The rhizoidal branches have oblique cross walls and grow down into soil. They help in anchorage and absorption.

The archegonium of Funaria typically possesses a long neck containing a series of neck canal cells, usually numbering between 6 and 10.

Funaria is anchored by multicellular, branched rhizoids that feature oblique septa.

Funaria spores contain chloroplasts, which allow them to begin photosynthesis immediately upon germination.

In Funaria, spore has small irregular mitochondria, numerous chloroplasts with poorly developed lamellae, small sparsely present dictyosomes and ER in the form of highly convoluted tubules near the plasma membrane.

Funaria possesses a juvenile filamentous autotrophic stage during life cycle, called as protonema. Moss plant (Funaria) develops on protonema as buds, while Marchantia is a liverwort in which distinct protonemal stage is absent.

Most amphibians undergo a significant physical transformation, known as metamorphosis, as they transition from their aquatic larval stage to their terrestrial or semi-aquatic adult stage.

Amphibians are ectotherms, meaning they rely on external environmental sources to regulate their body temperature. They do not generate significant internal body heat like endotherms.

Amphibian skin is thin and permeable, allowing for cutaneous respiration and the absorption of water directly from their environment.

Chordates are defined by specific developmental features like a notochord. Crabs are arthropods, which are invertebrates, and do not belong to the phylum Chordata.

All chordates possess a dorsal hollow nerve cord at some stage of their development. Features like hair, warm-bloodedness, or live birth are specific to certain classes, such as mammals, not all chordates.

Anemones are Cnidaria, slugs are Mollusca, and sponges are Porifera. This matches the classification provided in option B.
