The phloem, on the other hand, is continually pushed outward and compressed into the bark and is shed away. Because of the proximity of this xylem to the surface, injury to the bark, particularly ...

Xylem [zī' ləm] effectively sucks water and minerals from the earth, drawing nourishment into the roots, then upward along a tree's trunk or a plant's tender stem, into the aerial parts of the ...

The xylem serves as a means to transport water, nutrients and some hormones from the root, whereas the phloem is used predominantly for the distribution of the photosynthetic products and signals ...

Specialised plant cells include root hair, palisade, xylem and phloem cells. Find out more with Bitesize. For students between the ages of 11 and 14.

When we think about trees, we often imagine them growing from the soil, but did you know that less than 10% of a tree's weight comes from the soil? The rest of the tree’s bulk comes from somewhere ...

The phloem water flow rate Q going from the xylem to the roots (blue arrows, Fig. 1b) is driven by the osmotic pressure in the phloem, and can be expressed as (2) R tot Q = R T c + P X − P R ...

In xylem cells the fibers provide strength in the form of wood; the vessels allow water and nutrient flow to the leaves. Cells to the outside make up the phloem, which transports sugars, amino ...

Water moves in plants via the xylem in cells called conducting elements. The movement is along a water potential gradient from higher to lower concentrations from soil into the root, root to stem ...
