What is Coniferophyta used for?
The conifers are very important economically because they provide wood and wood products that are used to make buildings, furniture, and paper. Before petroleum was widely used, conifers were also the source of many important organic chemicals used to make paint and other finishes, solvents, and oils used by industry.
What does the word Coniferophyta mean?
Coniferophyta – cone-bearing gymnosperms dating from the Carboniferous period; most are substantial trees; includes the classes Pinopsida (subdivision Pinophytina) and Ginkgopsida (subdivision Ginkgophytina) and Taxopsida (subdivision Taxophytina) which in turn include the surviving orders Coniferales and Taxales (yews …
What are five examples of the Coniferophyta?
Five examples of plants that are members of phylum Coniferophyta are redwood trees, junipers, cypress trees, spruce trees, and hemlocks.
How do you identify a Coniferophyta?
Coniferophyta
- Has vascularisation.
- Have leaves, roots and stems (stems are woody and leaves are waxy and needle-like)
- Reproduce by non-motile gametes (seeds) which are found in cones.
- Examples include pine trees and conifers.
Where are Coniferophyta found?
Conifers are most abundant in cool temperate and boreal regions, where they are important timber trees and ornamentals, but they are most diverse in warmer areas, including tropical mountains.
Is Filicinophyta vascular?
Filicinophyta (Pterophyta) A phylum of mainly terrestrial vascular plants (see tracheophyte) – the ferns. Only the tree ferns have stems that reach an appreciable height. There is a characteristic uncurling of the young leaves as they expand into the adult form.
What is a non conifer Gymnosperm?
Non-coniferous Gymnosperms Cycads, which resemble palm trees (palms are angiosperms, unlike cycads), are also gymnosperms. Another group of non-coniferous gymnosperms is the Gnetophyta division which is broken up into three genera (Ephedra, Gnetum, and Welwitschia.)
What is the common name for Coniferophyta?
Conifers
The coniferophyta common name is “conifer”. Conifers’ thin, pointy leaves are probably their most noticeable characteristic, but they’re named after their reproductive products: the cones.
What are examples of Ginkgophyta?
Ginkgophyte, any member of the division Ginkgophyta, a group of gymnospermous plants of particular interest to paleobotanists. Two of the three genera of ginkgophytes, Ginkgoites and Baiera, are extinct. The third genus, Ginkgo, has only one member, Ginkgo biloba, commonly called the ginkgo tree.
What stage is dominant in gymnosperms?
sporophyte
In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant. The haploid phase is also dominant among fungi.
Is a pine cone a Coniferophyta?
The coniferophyta common name is “conifer”. Conifers’ thin, pointy leaves are probably their most noticeable characteristic, but they’re named after their reproductive products: the cones. It’s conifers’ reproductive method that really sets them apart from other divisions, or phyla, of plants.
What phylum is a conifer in?
The conifers, which are woody plants consisting mostly of evergreen trees, make up the phylum Coniferophyta, one of four phyla of gymnosperms that have living representatives. The word “conifer”means cone-bearing.
What are examples of coniferous trees?
A coniferous tree is defined as a tree with excurrent structure, possessing needles, usually green in colour, either borne as a single needle or in clusters on dwarf shoots. Examples of coniferous trees are larches (Genus Larix) and pines (Genus Pinus).
What is a conifer plant?
A conifer is any plant belonging to the class Coniferinae. Both trees and shrubs fall into this group, though the majority of conifers are trees. Coniferous trees are most easily identified by the cones that they bear. A conifer tree must bear its seeds in one of two ways.
What is a conifer cone?
Conifer cone. A cone (or pine cone ) is an organ on plants in the division Pinophyta (conifers) that contains the reproductive structures. It is the part of a tree that lets the tree reproduce.
