What is the meaning of the term Phreatophytes?

What is the meaning of the term Phreatophytes?

A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone (zone of saturation) or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture.

How do phreatophytes obtain moisture?

Phreatophytes are deep-rooted trees and shrubs that obtain a dependable water supply from the “phreatic surface” (Meinzer 1927), i.e., from the saturated water table, and thus maintain water status that is largely independent of soil water derived from incident precipitation.

What is a phreatophyte plant?

Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots.

What do ad Phreatophytes consume water through?

Most trees and other plants have root systems that grow less than three feet deep and pull water from soil. A small number of species called phreatophytes have root systems capable of reaching deep into groundwater supplies. That helps them survive in arid and semiarid climates where soil moisture is scarce.

What do you mean by Guttation?

: the exudation of liquid water from the uninjured surface of a plant leaf.

What is capillary water?

Capillary water is held in pores that are small enough to hold water against gravity, but not so tightly that roots cannot absorb it. This water occurs as a film around soil particles and in the pores between them and is the main source of plant moisture. As this water is withdrawn, the larger pores drain first.

What is the difference between Xerophyte and Phreatophyte?

is that “xerophyte” is any plant suited for life in a habitat where water is scarce, such as in a desert or chaparral. Such plants may be succulent, have small or reduced leaves, or spines and “phreatophyte” is any plant, typically living in deserts, that obtains its water from long taproots that reach the water table.

Where is the saturated zone located?

The phreatic zone, or zone of saturation, is the part of an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. Above the water table is the vadose zone. The phreatic zone size, color, and depth may fluctuate with changes of season, and during wet and dry periods.

Do epiphytes have roots?

Epiphytic plants are sometimes called “air plants” because they do not root in soil. However, there are many aquatic species of algae that are epiphytes on other aquatic plants (seaweeds or aquatic angiosperms).

Why is guttation important?

Guttation is the expelling of excess water or nutrients through tiny openings on leaves and stems. This biological process enables plants to restore balance to their nutrient and water content.

What is guttation very short answer?

Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and a number of fungi. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface. Guttation generally happens during the night time.

What is the function of capillary water?

Capillary Action …..in Action! Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

Which is the best definition of phreatophyte?

Definition of phreatophyte. : a deep-rooted plant that obtains its water from the water table or the layer of soil just above it. —.

Where are Phreatophytes found in the arid zone?

Phreatophytes are not only characteristic of arid or desert zones, but also of wetlands, floodplains, depressions that hold water and estuaries.

When was Phreatophytes first published by the Geological Survey?

Since 1927, when 0. E. Meinzer’s paper “Plants as indicators of ground water” was published as Geological Survey Water- Supply Paper 577, many reports and papers relating entirely or in part to phreatophytes have been released in various forms by the Geological Survey and other agencies. As more data on these
