Question

Characteristics of Spirogyra,mosses and ferns​

Answer 1

Characteristics of Spirogyra

Spirogyra is a filamentous green algae that is seen in fresh water bodies such as ditches, ponds and lakes. It is commonly called water silk. Spirogyra measures approximately 10 to 100μm in width and may stretch centimetres long.

Characteristics of Mosses

Moss grows on moist brick walls, on sidewalks, and as thick mats on forest floors. It is green, erect and is differentiated into leaves, axis and rhizoids. The main body of an adult plant is called a gametophyte. The rhizoids that anchor the plant are multicellular and branched with oblique septa.

Characteristics of Fern (Dryopteris)

Ferns are found in humid and shady places, both in tropical and subtropical climates. They can also be found in aquatic habitats. Ferns are vascular plants having xylem and phloem. Like all vascular plants, they have stems, leaves and roots.

Characteristics Are:-

• Spirogyra:-
Spirogyra is very common in relatively clean eutrophic water, developing slimy filamentous green masses. In spring Spirogyra grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen.

∆ Mosses:-
Mosses have several characteristics that distinguish them from other bryophytes. Only mosses have a multicellular rhizoid, a root-like subterranean tissue that absorbs water and nutrients from the soil.

• Ferns:-
Ferns stand out among garden regulars for their lack of flowers and seeds. Botanically, they belong to the division of non-flowering plants known as Pteridophyta.
