Non-vascular Plant
Non-vascular plants is a general term for those plants without a vascular system (xylem and phloem). Although non-vascular plants lack these particular tissues, a number of non-vascular plants possess tissues specialized for internal transport of water.
Non-vascular plants do not have a wide variety of specialized tissue. Liverworts have structures that look like leaves, but they are not true leaves because they have no xylem or phloem. Likewise, mosses and algae have no such tissues.
All land plants have a life cycle with an alternation of generations between a diploid sporophyte and a haploid gametophyte, but in all nonvascular land plants the gametophyte generation is dominant. In these plants, the sporophytes grow from and are dependent on gametophytes for taking in water and mineral nutrients and for provision of photosynthate, the products of photosynthesis.

Famous quotes containing the word plant:
“I grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.”
—Henry David Thoreau (1817–1862)
