Tracheophyte

Definition
noun, plural: tracheophytes
A vascular plant contains the conducting systems which consist of xylem for conveyance of water and phloem for conveyance of food such as sugar.
Supplement
Tracheophytes are commonly known as vascular plant that contains lignified and non-lignified tissues which includes the angiosperm, clubmosses, ferns, horsetails and gymnosperms. These kinds of plants have vascular tissues that able to grow in large size compare to the non-vascular plants wherein nutrients and water in the form of organic solutes distributed throughout the plant body by the xylem and the organic compound such as sugar produced during photosynthesis in leaves are disseminated by the phloem through sieve tube elements.
Tracheophytes growth starts from principal generation phase sporophytes which are typically diploid with two sets of chromosomes per cell compare to the generation phase of non-vascular plants which begin as gametophyte that are haploid with one set of chromosomes and only the spores, stalk and capsule are diploid.
Herbaceous tracheophytes are plants without wooded stem such as the yearly flowering plants petunias and other perennial ornamental plants like ferns, lavender or aster as well as fruits and vegetables like lettuce, strawberries and tomatoes.
Tracheophyte comprises 260,000 species including all the prominent flora of the Earth and believed to have originated from green algae wherein fossils have been discovered 400,000,000 years ago in Silurian rocks.

• non-vascular plants
