how does moss get nutrients and water?

Question

Ummm-i have a hw thing due tomorrow-and i am having lots of trouble with this one!!!! help meeee!!!

Answer 1

Bryophytes receive their water from rainfall and most of their nutrients are dissolved in this water that accumulated as dust on them. Their nutrient uptake is effected by the osmotic effect. Highly concentrated nutrients can kill them because they have no ability to regulate the absorption.

Bryophytes, being prostrate, have much of their surface in contact with their substratum and readily absorb moisture this way. Water is drawn along the surface of these plants by capillarity. Mosses have small, threadlike basal processes which look like roots. These are simply rhizoid holdfasts. It is likely that the rhizoids absorb water, but only because almost everything in a moss absorbs water. However they have no specific vascular structure, instead they sequester water in storage cells. From these cells water diffuses. They also use the turgor pressure of these storage cells to satisfy much of their modest need for structural support.

In certain mosses hydroids tissues form the moss water storage cells and might act as xylem, while leptoids might be homologous to phloem. (The xylem provides a passage for water and dissolved ions from the root system to the leaves. The phloem transports synthesized organic food from the leaves to other parts of the plant.)


Gases simply diffuse across the plant surface but liverworts also have special pores which are permanently open for gas exchange. Certain mosses also have stomata on their capsules (sporophytes).
