The leaves channel the water to the area at the edge of the leaves...this is where the most efficent water absorbing roots are, so they are getting more water by providing "shelter"....;

Soil absorbs moisture. It has small openings and the water gets in the small holes. The cohesion and adhesion of the water constitute a force that keeps the water in the soil, to a certain extent.

twigs usually have water. Its possible to dry them out.\n\nRocks can be porous enough to trap water inside them.

Osmotic pressure refers specifically to the difference in the concentration of elements between two solutions.  If you place a semipermeable barrier between the two solutions, water will flow across that barrier until the concentrations are equal.\n\nIn this way, when you put a freshwater plant into salt water, the fresh water flows out from the plant through the cell membranes, which are semipermeable to water but not salt.\n\nThis osmotic pressure is actually how your kidneys work, to filter fresh water from the fluid you drink and leave a more concentrated solution behind.  See the links below for more details.

I'm going to assume you are talking about plants. It depends. More transpiration means more water flows through plants, so of course more nutrients will enter the plant tissue. However, the amount that is actually absorbed for use by the plant is controlled by the plant cells.... excess minerals are usually stored.

Try this website, it has some good explanations of things like total dissolved solids, dissolved carbonates, boron, and other things often found in water used for growing plants. There's even a little information that is specific to grasses. \nhttp://www.ext.nodak.edu/extpubs/ageng/irrigate/eb66w.htm#plants\n\nBy the way, I found this using the search terms:\nirrigation water\nSo if you want to duplicate my search and see other results this should get you going.

Trees do NOT get water to their leaves using cappilary action alone. Cappilary action could lift water to maybe 10 metres maximum. The tallest trees are over 8 times that height. Cappilary action plays only a small, albeit vital, role in lifting water in trees.\n\nThe simple answer is that the tree uses the equivalent of a siphon effect to lift the water. A siphon works because water is cohesive, IOW water sticks to water. That cohesiveness of water in a siphon tube means that as water at one end falls it is able to suck more water up from the other end. Provided that the fall is greater than the rise you are trying to overcome you can use a siphon to lift water to significant heights.\n\nA tree trunk is basically composed of masses of siphon tubes filled with water, but it doesn't have any physical 'fall' component. Instead what the tree uses is the force generated by evaporation. As water enters a leaf it is exposed to the air and allowed to evaporate. Because water is cohesive that loss of water creates a negative pressure that pulls more water into the leaf within the leaf, and that in turn creates a negative pressure that pulls water into the vessel elements of the branch and the trunk. That pressure is sufficiently high to lift water to the tops of the tallest trees.\n\nWhich is why trees use such massive quantities of water. Even a small tree will use over 100 litres of water a day and less than 1% of that will be used physiologically. The rest is simply evaporated off to draw more water up the stem. It's an incredibly wasteful process.\n\nThis is also the reason why trees in dry environments are invariably shorter than plants in wetter environments. Because the system functions like a siphon the water column in the trunk can never be allowed to break or the pressure inside will immediately drop to zero. It's like getting vapour lock in a fuel line and plants can't re-prime the line. There has to always be sufficient water in the ground to feed the negative pressure required in the column. The taller the tree the greater pressure required and hence the more water required. As a result the maximum height of tree is determined in large part by the amount of water available.

Materials, dissolved (or semi-dissolved?) in water, are moved up and down the plant through the xylem and phloem, such as the previous posts say.  An additional factor to think about is that materials and water also move about because of differences in pressure within the vessels of the plant. At the leaf surface, heat and wind are drying the water that is present.  As this water "dries out" of the plant through the stoma, it creates a vacuum within the vessel it was in.  This, in turn, pulls water up through the plant to replace itself (physics-search for pressure, STP). This whole process is called Transpiration.  Adhesion, thus capillary action, would not be sufficient enough a force to distribute water to the highest part of the plant.

plants contain vascular tissue, a type of tissue that is spcialized to conduct water and nutrients through the body of the plant. they contain key cells in xylem, a form of vascular tissue that carries water upward from the roots to every part of the plant. the second type of vascular tissue is called a phloem. It transports solutions of nutrients and carbohydrates prouced by photosynthesis. xylem and phloem move fluids around the plant body, even against the force of gravity.

Water equalizes the pressure between the outside and the inside of the cell wall, so it doesn't become damaged.  It also is the transport medium for nutrients coming in, and waste exiting.

How capillary action makes water go up...???\n\nEven though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action (pronounced kap uh LAR ee, is the tendency of liquids to move into or out of tiny, hairlike passageways) . This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plant's roots upwards to the plant's highest leafs via capillary action. Try this experiment to see capillary action in action.\n\nWrap the plastic wrap around the knitting needle and then tape the edges so that you have formed a tube. Remember, the narrower the tube, the more pronounced the capillary effect will be. \nOnce you have taped the plastic wrap, pull out the knitting needle. Make sure that the new plastic tube is not bent and is open at both ends. \nNow pour a little of the food coloring into a glass half filled with water. \nNow place your plastic tube into the glass of water. \nExamine the tube carefully. The dye should climb up the tube above the level of the liquid in the glass. \nNow try the same experiment with varying levels of water in the glass. Does this make a difference?

In a hypertonic solution the water inside the cell leaves, causing the cell to shrivel.  Since a plant cell has a cell wall, the cytoplasm and plasma membrane will shrink away from the cell wall (called plasmolysis).  This decrease in turgor pressure means the plant will wilt.

When plants take in H2O and minerals, the concentration changes from that of the surrounding soil. The concentration difference causes the plant to absorb more water and nutrients(including salt). For plants exposed to large amounts of salt in a short time, this means they absorb more than they need. As they have no way to get rid of it(with the exception of the mangrove), the plants end up dying.

That is xylem.\nPhloem transports manufactured materials, e.g. sugars.\nLook here:

One of the difficulties that water plants have that land plants do not is gas exchange.  Plants need to be able to get air to their roots and aquatic plants usually do this through special tissues that lead to the air.

It supports the plant.It also contains the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant.The phloem transports food made in the leaves to the rest of the plants. :)
