Explanation / Answer
Answer 2. The name of the structure where the egg forms is known as archegonium.
Answer 3. Mosses lack true roots, stems and leaves. They reproduce with the help of spores. Mosses are so small in size that they do not require xylem and phloem like structures to carry water and can do this by simple diffusion, thus eliminating the need for roots, stems and leaves.
Answer 4. The haploid stage is the dominant part of the moss life cycle. In haploid stage, a multicellular haploid gametophyte develops from a spore and produces haploid gametes.
Answer 5. The small dots that are ejected from the capsule are known as spores. Spores are used for reproduction of mosses.
Answer 6. These structures known as spores become rhizoids and then eventually develop into mature gametophytes as the life cycle develops.
Answer 7. Sphaganum moss, also known as peat moss is used as a "soil conditioner" as it increases the nutrient and water holding capacity of the soil by increasing the capillary forces and cation exchange capacity.
