The stems provide the vital role of carrying water, as well as other nutrients, from the roots to the leaves. These are carried to the leaves by the xylem and the phloem and which carries food made by the leaves to the rest of the plant. ... Sapwood consist of xylem that still works in the process of carrying water and minerals to the leaves. ... With the movement of water from the rest of the plants water will be taken away from the leaves reducing the plants ability to photosynthesis. The lack of water will also cause cell plasmolysis. ...

FUNCTIONS OF WATER A plant is made up of about 95% water, this being the main part of all living matter. ... In order to survive, any organism must carry out a complex and chemical reaction. ... Thus the pathway of water through a plant is described as three distinct stages; water uptake; movement up the stem; and transpirational loss through the leaves. 1 Water Uptake. ... The cortex is often quite extensive and water must travel across it to reach the central region which is the transporting tissue called the stele in which is the phloem and xylem. ... Movement of water up the stem. ...

It is important for respiration to occur in the cactus because it will provide the cactus with ATP energy so that it can carry out life processes such as growth, which is necessary for it to survive. ... If the stomata did not close due to water stress the cactus would lose lots of water and would not be able to replace water at the same rate that it loses water. ... A structural adaptation of the rose is that it has an extensive root system. 10 This is important because it ensures that the plant can absorb sufficient amounts of water and minerals from the soil through the xylem and phloem c...

In some very rare cases, however, a plant is able to carry on its activity without the use of chloroplasts. ... Dodders can cause many of these diseases, including pear decline, aster yellows, tomato big bud, vinca virescence and elm phloem necrosis (Ristau 1998). ... A good example of this is the rickettsia-like bacteria that inhabit in the phloem tissue. ... Water, harvesting, and soil movement then spread the seeds, and the cycle starts again. ... It is near impossible to remove the dodder seeds, and the majority of the time they are disseminated in soil or carried off by flowing water...

Plants are autotrophs, and can carry out photosynthesis to produce their own food. ... Cuticles developed as a way to retain more water. ... Stomata are tiny openings that allow for water and gas diffusion in and out of the plant. ... The xylem conducts water and minerals up from the roots, while the phloem conducts sucrose and hormonal signals through the plant. ... Certain reproductive strategies developed that allowed less dependance on the need of standing water. ...

The epidermis sucks water in. ... The stele contains the xylem and phloem. ... These forces that move the wonderful water affect the water potential..Water potential is the potential energy of water in a particular system compared to the potential energy of pure water at the same atmosphere pressure and temperature. The movement of water in plants is determined by water potential differences.Water potential measurements predict which way they will move. ... They are nonvascular plants because of the fact that they lack the xylem and phloem tissues that other plants have. ...

Why do trees need water? ... Additional water transpires through the pores in their leaves. ... (This is also known as the "phloem.") That suction must be strong enough to suck water out of the soil. The amount of force needed depends on the amount of water in the soil (a drier soil holds water more tightly), as well as the height to which the water must be lifted (a greater height requires more force, while a lesser height requires less force). ...
