How does water get up to the top of tree?

Answer 1

water exaporates frm the leaves and other parts of the plant above the ground. The evaporation of water from the plant is called ''transpiration''. It occurs mainl through the stomata. However, as quickly as water is lost from the leaves, more water enters the roots and flows up the stem.

The water flows up the plant in narrow pipes, rather like capillary tubes. These tubes make up the xylem. The walls of the tubes are made of lignin, which is hard and waterproof. In trees and shurbs the xylem tubes are one of the main components of wood. They do not contain living material and are therefore dead.`

Water rises up the stem mainly by being ''pulled'' from above. The ''pull'' is created by the evaporation if water from the leaves. If you stop this by, for example, cutting iff the leaves or blocking the stomata, the flow of water up the stem slows down or stops.

The drier the atmosphere, the greater is the rate of transpiration. In very dry wather, water may evaporate from the leaves faster than it is replaced from the soil. The plant then suffers from water shortage.

Normally a plant's cells are full of water, and all the cells are pressing against each other within the epidermial covering. This helps to support the plant amd holds the leaves out flat.

If a plant runs short of water, the cells lose water and go flabby. The plant then droops. This is called wilting. Plants living in dry places have all sorts of adaptations for preventing this.

Answer 2

Water is carried up a tree through the xylem tissue in the process of Transpiration. Since there is constant evaporation coming from the leaves, it creates a continuous flow of water from the roots to the chutes. The roots are what absorb the vast majority of water a tree needs. Both cohesion and adhesion allow water to move up a tree - no matter how tall the tree is. Cohesion helps the individual water molecules stick together in one continuous stream. Adhesion allows the water molecules to adhere to the cellulose molecules found in the walls of xylem cells. Once the water makes it to the leaf, it evaporates, allowing more water molecules to be drawn up through the tree again in this ongoing cycle.

Answer 3

Water is absorbed by the roots of the tree and is then pulled upwards through the xylem vessels by a process called transpiration. Transpiration is the evaporation of water from the leaves, creating a negative pressure that pulls more water up from the roots to replace what has been lost. This continuous flow of water helps transport nutrients from the soil to the leaves and helps maintain the tree's structure and temperature.
