Question

(A)Irish moss
(B)Bog moss
(C)Club moss
(D)Reindeer moss

Answer 1

Hint: The true moss comes under the genus of Sphagnum. It is also known as the peat moss. Sphagnales is the order of the true moss and the class is Sphagnopsida.

Complete answer:
Peat moss, also called bog moss or Sphagnum moss, comes under the category of true moss. True mosses generally grow up to 10 cm in length and develop a carpet-like, dense structure and are also non-vascular plants. True mosses attach to their substrates like soil or wood via rhizoids and live a gametophyte-dominated life cycle.

Additional Information: It was seen that the Sphagnum has a distinct structure as they are adapted to the watery habitats.
The top of the plant is known as the capitulum, it is known as a rosette or collection of leaves that contribute to the majority of the plant's energy through photosynthesis. The main body of Sphagnum consists of a stem and branches, with leaves also protruding from both the stem and the branches.
Sphagnum mosses are seen mainly in the Northern Hemisphere in conifer forests, and moist tundra regions. In the Southern Hemisphere, peat is found in southern Chile and Argentina, part of the vast Magellanic moorland. As Sphagnum moss starts growing, it can slowly spread into the conditions or areas which are dry thus forming larger mires, both raised bogs, and blanket bogs. The Sphagnum are said to be ‘habitat manipulators’ as they can influence the dry habitats composition. When the peat accumulates, then provide habitat for a wide array of peatland plants, such as sedges and ericaceous shrubs, and even some orchids and carnivorous plants.
So, the correct answer is ‘Bog moss’.

Note: Moss is available to us in two forms i.e dried moss and Preserved moss. Dried moss is present at the dormant state and as time passes will lose its green color but when rehydrated it will return to life and start growing again. Preserved moss is a dead moss and has been chemically treated to maintain its feel and allure.
