The plant we recognize as a fern is the diploid sporophyte generation. For a moss plant to complete their life cycle, they require water and here water acts as a medium for flagellated sperm to reach the egg and undergo fertilization. A single spore germinates to form a branched, filamentous protonema, from which a leafy gametophyte develops. Transport is the physical movement of people and commodities from one place to another. In the common haircap moss, Polytrichum commune (shown here), there are three kinds of shoots: In early spring, raindrops splash sperm from male to female plants. Sperm cells are carried to the female sex organ in a film of water, and one fertilises an egg cell.

Compare the life cycles of fungi from the phylum Ascomycota with those from the phylum Basidiomycota. Basic Fern Anatomy Why are mosses small in size in comparison to vascular plants? List the adaptations that led to a land existence for plants. The ferns ( Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. Describe the structure and mode of operation of the repulsion type moving iron meter. The typical fern, a sporophyte, consists of stem, leaf, and root; it produces spores; and its cells each have two sets of chromosomes, one set from the egg and one from the sperm. What is the difference between xylem and phloem? Although they all contain the same genes, they fall into two distinct groups with respect to the organization of their genes. Hence, mosses cannot complete their life cycle in a dry environment. How are ferns and seed-bearing plants similar? (a) Ferns lose water from vascular tissue easily, so plant height is limited by water availability and retention. Gametophyte plants are haploid, sporophyte plants diploid. Liverworts have a thin, leathery body that grows flat on moist soil or, in some cases, the surface of still water.
