Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water. [citation needed] Non-vascular plants include two distantly related groups: Bryophytes, an informal group that taxonomists now [update] treat as ...
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase.
The word herbaceous is derived from Latin herbāceus meaning "grassy", from herba "grass, herb". [9] Another sense of the term herb can refer to a much larger range of plants, [10] with culinary, therapeutic or other uses. [6]
It is a perennial herbaceous plant, with elliptic, obtuse leaves. It grows as a vine or creeper, doing well in moist, neutral soil. Its most striking feature is the color of its flowers, a vivid deep blue; solitary, with light yellow markings. They are about 4 cm (1 + 1 ⁄ 2 in) long by 3 cm (1 + 1 ⁄ 4 in) wide. Some varieties yield white ...
Most vines are flowering plants. These may be divided into woody vines or lianas, such as akebia wisteria, kiwifruit, and common ivy, and herbaceous (nonwoody) vines, such as morning glory. One odd group of vining plants is the fern genus Lygodium, called climbing ferns. [10] The stem does not climb, but rather the fronds (leaves) do.
Vascular plants have vascular tissueswhich distribute resources through the plant. Two kinds of vascular tissue occur in plants: xylemand phloem. Phloem and xylem are closely associated with one another and are typically located immediately adjacent to each other in the plant. The combination of one xylem and one phloem strand adjacent to each ...
Spermatophyta. A pteridophyte is a vascular plant (with xylem and phloem) that reproduces by means of spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as " cryptogams ", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses ...
