Like other plants, pteridophytes constitute a good source of food to animals. Sporocarps of Marsilea, a water fern, yield starch that is cooked and eaten by certain tribal. (2) Soil Binding: By their growth pteridophytes bind the soil even along hill slopes.
Are pteridophytes of any economic importance are they of any use to humans?
Economic Importance of Pteridophytes: The economic importance of pteridophytes is not well-documented, because due attention has not been given towards their use in human welfare. However, there are many reports on their uses, specially as food plants, medicinal plants and horticultural plants.
What is main feature of pteridophytes and discuss its the economic importance?
Economic importance of pteridophytes Ferns are grown as ornamental plants for their beautiful fronds. The rhizomes and petioles of the fern Dryopteris yield a vermifuge drug. The sporocarps of Marsilea ( a water fern) are used as food by certain tribal people.
Why are pteridophytes important to humans?
In general, ferns are of minor economic importance to humans. However, ferns are popular horticultural plants and many species are grown in ornamental gardens or indoors. Herbalists have advocated some fern species for treatment of ulcers, rheumatism, intestinal infections, and various other ailments.
What are the main features of pteridophytes?
Pteridophyta Characteristics
- Pteridophytes are considered as the first plants to be evolved on land:
- They are cryptogams, seedless and vascular:
- They are cryptogams, seedless and vascular:
- Spores develop in sporangia:
- Sporangia are produced in groups on sporophylls:
- Sex organs are multicellular:
What is 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.

Why are mosses so important?
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.
