Ascent of xylem water is also known as the ascent of sap as sap contains minerals dissolved in water. Ascent of sap is actually the movement of sap from the roots all the way to the leaves where it can be utilized in photosynthesis. There are two prposed theories so as to exlain the ascent of sap. One is the "Root Pressure Theory" which says that root exerts a pressure on the water to push it upwards by absorbing more from the soil. But this pressure works only for a few metres. The second theory is more acceptable; "The transpiration Pull". According to this one, when water is transpired through the leaves, the evaporating water molecules pull the ones after them with the help of the adhesive and cohesive forces. This helps in the ascent of water from the roots, all the way through the xylem, to the leaves.
Xylem gets water from the roots of a plant
The Xylem tissue transports water and nutrients from the roots.
Because xylem is a vessel that water travels through.
This is the vascular tissue xylem.
Xylem cells are responsible for supplying water to all parts of the plant. They make up the xylem tube which transports water, but then they die. So the xylem tube which is made up of dead xylem cells is responsible for transport of water in the plant.
Xylem tissue by ascent of sap
Water molecules adhere to the xylem walls and are carried up by transpirational pull during ascent of sap, which is an essential process for plant life.
Xylem gets water from the roots of a plant
Water is transported by the xylem.
Xylem cells carry water and nutrients from the roots to other parts of a plant.
The Xylem tissue transports water and nutrients from the roots.
it's called "xylem" your welcome
Because xylem is a vessel that water travels through.
.food is carried by phloem and water is carried by xylem.
This is the vascular tissue xylem.
Xylem cells are responsible for supplying water to all parts of the plant. They make up the xylem tube which transports water, but then they die. So the xylem tube which is made up of dead xylem cells is responsible for transport of water in the plant.
Xylem transports water throughout the plant.
