Transcript of Mosses (Bryophyta)
are non-vascular plants
are able to draw up water using osmosis
does not have xylem and phloem cells
do not have roots but have rhizoids
are highly dependent on water
reproduces sexually and asexually
noted for their intense shade of green
are small plants
do not have seeds or flowers OSMOSIS Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. STRUCTURES OF MOSSES Seta & Sporophyte Stems and Leaves Gametophyte Rhizoids Capsule/ Sporongium It contains the spores of the moss plant. It would fall off if the spores are matured enough and release the spores. Gametophyte translates to "gamete plant." It produces gametes of the plant characterized by the alternation of generations. These are structures that helps the moss reproduce asexually. HABITAT NUTRITION REPRODUCTION ECOLOGY THREE SPECIES OF BRYOPHYTES MOSSES A sporophyte, also known as "spore plant," produces hundreds of spores. Sporophytes are located at the sporophyte stalk named "seta." At the tip of the seta is the sporangium or the spore capsule. REFERENCES: http://www.ehow.com/list_7402699_parts-moss-plant.html
http://science.jrank.org/pages/1051/Bryophyte-Importance-mosses.html Like all leaves, moss leaves are for photosynthesis and providing nourishment for the plant. During dry seasons, moss leaves folds/ curls up in order to protect the plant. When exposed to moisture, it will unfold. Rhizoids are rootlike structures that anchor to the substrate in order to hold the plant while the moss is growing. It absorbs the nutrients and water as well. Mosses are abundant in WET habitats.
eg. swamps, bogs, streams, shady sites and rainforests
Some are submerged in streams and lakes. URBAN MOSSES
Mosses that can cope with petrochemicals and dust in the air. They can take root in concrete, bitumen, cracks, crevices in footpaths, walls, gutters and drains. Generate nutrients through photosynthesis Most of them can also absorb water and dissolved minerals over the surface of the gametophore a part or structure bearing gametangia.
reproductive organs Can reproduce asexually/ sexually. Fertilization is dependent on water.
sperm travels through water MOSSES Multicellular rhizoids
development: the spore-bearing capsule enlarges and matures after its stalk elongates
clearly differentiated stem with simple-shaped, ribbed leaves without deeply lobed or segmented leaves and not arranged in three ranks Liverworts Unicellular rhizoids
development: the capsule enlarges and matures before its stalk elongates
lack of clearly differentiated stem and leaves in thallose species, or in leafy species the presence of deeply lobed or segmented leaves and the presence of leaves arranged in three ranks Hornworts They have SLIME PORES
= stomata develop internal mucilage-filled cavities
invaded by cyanobacteria
HORNworts SEXUAL REPRODUCTION ASEXUAL REPRODUCTION through SPORES soil builders
