What are vascular and non-vascular plants?
Vascular plants are also known as tracheophytes. They contain vascular tissues, i.e. xylem and phloem. Xylem is a lignified tissue that conducts water and minerals to the plant parts from the root. Phloem is a non-lignified tissue that conducts food produced by photosynthesis to other parts of the plant. Xylem and phloem are arranged in close proximity and in a well-defined pattern to form vascular bundles. Vascular plants possess true stems, roots, and leaves. The main plant body is the sporophyte, which is diploid. Vascular plants include pteridophytes, gymnosperms, and angiosperms.
Non-vascular plants, as the name suggests, lack vascular bundles. They are small in size and may possess simpler structures for the conduction of water and nutrients. Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems, and leaves. Xylem and phloem are absent. Bryophytes include liverworts, hornworts, and mosses. The main plant body of non-vascular plants is a haploid gametophyte, which is the dominant stage of their lifecycle. Non-vascular plants are often called pioneer species that colonize first in the newly created.
