Water is absorbed or imbibed by the roots under the ground. Water is then transported up the stem to the leaves through a tube called xylem which is made of dead cells.
There are two types of xylem: vessel element and tracheids.
Vessel element is more efficient transporting water because they use perforation or holes. Tracheids, however, can both tranport water and give support.
The movement of water 'fighting' against gravity can be explained by the Cohesion- tension theory. The three major concepts in this theory are:
-Transpiration: the evaporation of water from plants. This causes negative pressure.
- Cohesion: water molecules tend to stick together.
- Bulk flow: when a water molecule is lost from a leafby transpiration, it pulls up behind an entire column of water molecules.
Other minor contributions to movement of water:
-capillary action
-osmosis (root pressure)
Xylem takes water up, and phloem [pronounced flow em
] brings nutrients down. Remember it by the common letter "u" in up and xylem,and by water flows [sounds like phloem] down.

The vascular tissue xylem carries water from the roots of the plant to the leaves of the plant via the stem of the plant.
Xylem tube cells: There are also cells called phloem tube cells, which transport water up the plant to the leaves. These two types of tubes are found in the stem and the vains of a plant, in groups called vascular vundles.
Through a system of tubes.
the Xylem is the tube, which carries water up the plant. The Phloem tube carries sugars and nutriets in both directions, up and down the plant.
Stem
carries water to other plant parts
its called the stem
The roots takes water to all parts of a plant
The xylem delivers water and the phloem delivers food
The xylem tube carries the water from the roots to all parts of the plant, from bottom to top.This works because1 the water evaporates out of the leaves and so the water pressure causes the water to flow upwards.2 if the other parts of the plant have a lower concentration of water in them, the water will flow into them through osmosis. (water flowing from a region of high concentration to a region of lower concentration through a semipermeable membrane like the plant cells.)The phloem carries food from the leaves (and other food producing parts of the plant) to the rest of the plant, from top to bottom.
yes a stem carries water and nutrients to all parts of a plant and a elevater carries people to different parts of buildings
carries water and other nutrients throughout the plant.
A stem in a plant carries water that the roots suck up and sends it to the other parts of the plant. A cool thing you can doo to see this is take some celery, put it in a cup full of food coloring-filled water, and see what happens!!!!!!
The roots of the plant absorb water and nutrients from the soil. The xylem, a type of tissue in the plant, carries these materials upward from the roots to the rest of the plant, including the stem, leaves, and flowers.
The vascular tissue called xylem carries water to the leaves of the plant.
The vascular tissue xylem carries water from the roots of the plant to the leaves of the plant via the stem of the plant.
Stem is the only one that will transport the water,food,mineral salts and sugar(food) to all parts of the plant. Because of stems,the water and mineral salts get to the leaves and other parts of a plant.
