Both mosses and ferns
Fern
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the sporophyte is the dominant p…
What is the ecological role of mosses?
Ecologically, mosses break down exposed substrata, releasing nutrients for the use of more-complex plants that succeed them. They also aid in soil erosion control by providing surface cover and absorbing water, and they are important in the nutrient and water economy of some vegetation types.
What is the most important ecological contribution of mosses?
Mosses and other bryophytes play an essential role in ecosystems, because: It is able to retain up to 20 times its weight in water, absorbing excess water while it rains and releasing it slowly in dry weather.
Can you suggest any ecological role for mosses?
In addition to controlling soil climate, mosses regulate C and nutrient cycling in boreal ecosystems by (i) contributing to ecosystem net primary productivity, (ii) contributing to ecosystem N inputs via N-fixing symbioses with cyanobacteria (DeLuca et al.
What is the ecological role of liverworts and mosses to terrestrial environment?
Answer and Explanation: Mosses are referred to as ecologically important plants because these plants provide shelter to several invertebrates as well as insects.
Is moss useful to humans?
If you plant Moss in areas with low pH levels, it will help in reducing the growth of grass and other similar things. Studies also indicate that Moss is also used widely during WWII and WWI as a first aid to wounded soldiers, which shows that people still use it as an antibiotic.
What are the ecological roles of bryophytes?
Bryophytes also play a very important role in the environment: they colonize sterile soils, absorb nutrients and water and release them slowly back into the ecosystem, contributing to the formation of soil for new plants to grow on.
What are the economic importance of mosses?
Mosses are often used to condition the soil. Coarse-textured mosses increase water storage whereas fine-textured mosses provide air spaces. Peat mosses are the most important economically as they were, and still are, an important source of fuel in some countries. Peat is derived largely from Sphagnum moss.
How do mosses help start new biological communities?
Like all photosynthetic organisms, mosses are primary producers that build biomass through photosynthesis. They enrich ecosystems with organic matter, forming the basis of the food chain.
What are the characteristics of mosses?
Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients.
What is ecological importance of liverwort?
For example, liverworts play a significant role in the global carbon budget, plant succession, and nutrient cycling. As such, they have been used as indicators of past climate change, to validate climate models, and as early indicators of global warming.
What are the ecological and economic importance of bryophytes?
Bryophytes are very important in initiating soil formation on barren terrain, in maintaining soil moisture, and in recycling nutrients in forest vegetation. Indeed, discerning the presence of particular bryophytes is useful in assessing the productivity and nutrient status of forest types.
What ecological roles do liverworts mosses and hornworts play in the environment?
What ecological roles do liverworts, mosses, and hornworts play in their environment? Liverworts, mosses, and hornworts are all decomposers that help break down dead organic matter (nitrogen fixation, soil stabilization). The also act as shelter for many small organisms.
What are the ecological and economic importance of mosses?
Mosses are often used to condition the soil. Coarse-textured mosses increase water storage whereas fine-textured mosses provide air spaces. Peat mosses are the most important economically as they were, and still are, an important source of fuel in some countries. Peat is derived largely from Sphagnum moss.
Which of the following is not the ecological importance of moss plants?
Answer-(2) Very high water holding capacity of mosses is useful for trans-shipment of living materials is not an Ecological importance.
What are the economic importance of bryophytes?
Bryophytes are very important in initiating soil formation on barren terrain, in maintaining soil moisture, and in recycling nutrients in forest vegetation. Indeed, discerning the presence of particular bryophytes is useful in assessing the productivity and nutrient status of forest types.
Which of the following are of great ecological importance for soil formation?
Solution : Mosses along with lichens are the first orgainsms to colonis rocks and hence, are of great ecological importance. They decompose recks making the substance suitable for the growth of higher plants. Since mosses form dense mats ont the soil, they reduce the impact of falling rain and prevent soil erosion.
What are the roles of ferns in the environment?
Here’s a brief list of some of the amazing roles that ferns can play: provide microhabitats, as well as shelter and shade to small animals.
What is the role of a bioindicator in an ecosystem?
ceremonial and spiritual use or importance. colonize disturbed sites as one stage in succession. filter toxins, such as heavy metals, from environments and thus provide a bioindicator for the health of an ecosystem.
Why are lycophytes considered mystical plants?
Ferns and lycophytes were long considered as mystical plants, because people did not understand how they could reproduce without ever producing a flower, a fruit or a seed (Moran, 2004). In this book, we address the mystique that surrounds ferns by exploring fern ecology, or how ferns relate to their environment.

How do fern gametophytes develop?
It develops in a microenvironment characterized by little competition from other plants (including even mosses and algae); exposed humus, decomposing plant materials, or fresh mineral surfaces; deep to moderate shade; and a humid atmosphere. Even ferns whose sporophytes tolerate sun and drought tend to have these requirements for their gametophytes. On rocks, for example, the gametophytes form in protected crevices in which light is minimal and moisture maximal. Because of their requirements for exposed soil, development of fern gametophytes is promoted by damage to mature vegetation, such as fallen trees in the forest, flooding, and deep erosion. Prothallia are observed in nature most commonly upon shaded soil banks in forests and along streams and upon rotting logs.
What are the adaptations of ferns?
Ingmar Holmasen. Both epipetric (growing on rocks) and epiphytic ferns may show structural adaptations to dry habitats similar to those of some desert plants. These adaptive features include such specializations as hard tissues and thick texture; the surface cells, or epidermis, may be provided with a very thick cuticle (a waxy layer);
What is the main source of population dispersal?
The fern spore —a single living cell, usually protected by a thick wall—is the main source of population dispersal, being readily carried by wind. Ferns display a wide diversity of spore types in terms of shape, wall structure, and sexuality, and these types prove to have great value in determining taxonomic relationships.
Where do ferns grow?
Ecologically, the ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks; others are confined strictly to rocky habitats, where they occur in fissures and crevices of cliff faces, boulders, and taluses.
What is the name of the fungus that attacks ferns?
Fungi infect ferns, some of them producing soruslike (i.e., resembling the sorus, the sporangium cluster of ferns) dark bodies, or sclerotia. Snails and slugs commonly attack young, uncurling fronds (leaves) of some species, and various beetles have been observed to graze upon ferns.
Do ferns reproduce sexually?
As the bulk of reproduction of ferns is probably vegetative, taking place in the sporophytic stage, the presence of a large stand of a particular kind of fern results not so much from sexual reproduction by gametophytes as from clone formation by rhizomes and in some cases by root or leaf proliferations.
Do ferns need shade?
Ferns that grow in the open are often referred to as sun ferns (e.g., Gleichenia) and, unlike most ferns, do not (at least as mature plants) require shade. Water ferns —waterclovers ( Marsilea ), water spangles ( Salvinia ), and mosquito ferns ( Azolla )—surprisingly are very commonly inhabitants of dry regions.
