Conifers are gymnosperms or “naked seed plants” in the phylum Coniferophyta. Ferns are non-seed plants in the phylum Pterophyta. ... The zygotes then develop into adult plants called sporophytes. Conifers reproduce through pollination of ovulate cones that eventually develop seeds.
What type of tree is a conifer?
All extant conifers are perennial woody plants with secondary growth . The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.
What is the difference between fern and pine?
Conifers, such as pine trees, are naked seed vascular plants, also called gymnosperms. Instead of being completely covered by the parent plant, conifer seeds appear outside the plant in hanging cones. ... Ferns are seedless vascular plants.
What is the classification of conifers?
Conifer, any member of the division Pinophyta, class Pinopsida , order Pinales, made up of living and fossil gymnospermous plants that usually have needle-shaped evergreen leaves and seeds attached to the scales of a woody bracted cone.
Do conifers have true leaves?
They do have a well-developed vascular system of xylem and phloem and have true roots, stems, and leaves .
Do ferns have mycorrhiza?
During the Devonic period, the first plants with roots appeared on land, the ferns belonging to Pteridophyta, Filicales groups, still exist today. They are widely distributed, particularly in tropical environments, and many of them have roots colonized by arbuscular mycorrhizal fungi (AM) (Brundrett 2002).
What is the life cycle of a fern?
The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes . Gametophyte plants are haploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.
Are conifers poisonous to humans?
Not all pine varieties are edible, however; the ponderosa pine and several others varieties of pine trees can cause illness and death in cattle and other animals. One evergreen conifer, the yew, contains a toxic substance that is potentially fatal if ingested by humans .
What are conifers and ferns under which class do they come?
Conifers are gymnosperms or “naked seed plants” in the phylum Coniferophyta . Ferns are non-seed plants in the phylum Pterophyta. The groups have different life cycles. Ferns produce spores that develop into gametophytes.
Do conifers have veins?
Each conifer leaf has a single vein .
Is Fern a true plant?
Ferns are plants that do not have flowers . ... Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
What is the difference between mosses and conifers?
Ferns and mosses are different from conifers in their methods of reproduction, as ferns and mosses reproduce by using spores and conifers reproduce by...
Which phase is dominant in the life cycle of pteridophyta?
The fertilized egg or zygote undergoes the division of mitosis and forms the different parts like stems, roots, and sporophyte , and later spores are formed again through meiosis and spread by the dispersion, and, again the life cycle continues, so the sporophyte is the dominant phase of pteridophyte.
Which of the following is an aquatic fern?
Salvinia is a true aquatic fern with both annual and perennial species ( e.g., S. nutans) (e.g., S. Molesta). The plant body consists of a floating stem bearing on the upper surface two rows of large green hairy leaves, and strongly branched leaf roots on the lower surface.
How did mycorrhiza evolve?
Life first emerged on land during the pre-cambrian period (see Fig. 5 below for the geological timescale), when it was colonised by phototrophic micro-organisms , which were probably prokaryotic. Until fairly recently, it was believed that land plants became established during the late Silurian.
