Lesson 9 - Non-vascular Plants Flashcards
They are plants that do not have a vascular bundle, which is composed of xylem and phloem: most of them are small and prostrate to the ground.
Non-vascular plants
a simple, low-growing, nonflowering plant that lacks specialized conducting channels for transporting water and nutrients.
Non-vascular plants
Are considered nonvascular because they do not have an extensive transport system with xylem and phloem.
It is often said that they do not have “true” roots, stems and leaves.
Bryophytes
the body of a bryophyte
thallus
bryophyte gametophytes have gamete-bearing structures known as
gametangia
Male gametangia
Antheridia
Female gametangia
Archegonia
Is the scientific classification for mosses.
Phylum Bryophyta
are low-lying, tiny green plants that live in moist environments. these plants are more complex than algae and fungi.
Mosses
consists only of the genus Sphagnum, known as peat moss, one of the most widespread genera of mosses.
Spagnopsida
has a sheetlike protonema, rather than the typical threadlike shape found in most bryophytes.
Sphagnum
are frequently the only plant life encountered in dry, windy, cold mountainous microenvironments, where they live not only on rocks but also on the snow and ice itself.
Granite mosses
Includes the most familiar types of mosses, with many playing an increasing role as landscape since they are commonly known, they are often informally called “true mosses”
Bryopsida
a name given to a liver-shaped plant
liverworts
distinguished from other bryophytes by their prominent horn-shaped sporophytes, which give them their common name and the phylum name Anthocerophyta
hornworts
