Plant Assignment Pteridophytes be an ancient class of plants. Ferns do not f tear down, but in its stance regreen groceries by m all over of spore. in that respect argon over 10000 species of ferns world vast and the Australian flora consists of more than 400 species.

Gymnosperms are also vascular plants that encounter bare seeds that are not enclosed in ovaries. Their seeds are exposed on modified leaves (sporophylls) that usually have cones (strobili). Conifers triumph amongst Australias relict gymnosperms. The conifers usually grow slowly, live inordinately ample lives, use nutrients in moderation and retain their canopy over numerous days. Life rhythms of a fern and a quick are complex. The main similarities in the first stage of the animation cycle of a fern and suffer is that both the plants have the diploid sporophyte generation.

The fern and the pine also use meiosis division to produce haploidic spores or megaspores for reproduction. There are numerous differences amid these plants. The pine is heterosporous; this means that it produces cardinal opposite spores of different size and sex. Each is produced in different parts of the plant. The male p! erson gametophyte is produced in the pollen, while the female gametophyte is produced in the cone. Female cones are large than male cones and usually take up to two years to mature. On the other hand the fern reproduces asexually. Fern trees frond bear groups of sporangia on the lower surfaces. Haploid spores are formed in the spore sac next meiotic division.
