Sentences with phrase «xylem tissue»

What does xylem tissue carry?

They say the size of the pores in sapwood — which contains xylem tissue evolved to transport sap up the length of a tree — also allows water through while blocking most types of bacteria.

This unique situation comes about because the xylem tissue in oaks has very large vessels; they can carry a lot of water quickly, but can also be easily disrupted by freezing and air pockets.

Xylem tissue is found in all growth rings (wood) of the tree.

A single tree will have many xylem tissues, or elements, extending up through the tree.

Not exact matches

The xylem (the scientific name for wood) is the non-living tissue of a plant that transports water and nutrients from the soil to the stems and leaves.

Like the vascular system in people, the xylem and phloem tissues extend throughout the plant.

This sapwood consists of conductive tissue called xylem (made up of small pipe - like cells).

Water and other materials necessary for biological activity in trees are transported throughout the stem and branches in thin, hollow tubes in the xylem, or wood tissue.

Typically, when plants become extremely dehydrated and water pressure drops, air bubbles can develop in the xylem, tissue that carries water up from the roots (SN: 05/14/16, p. 32).

The wood is composed of xylem, porous tissue that conducts sap from a tree's roots to its crown through a system of vessels and pores.

Fossilized slices of a 374 - million - year - old tree reveal a hollow core surrounded by numerous bundles of woody strands called xylem (the larger black spots), with soft tissue (in gray) between.

The researchers focused on the secondary cell walls in a type of plant tissue called xylem from the Arabidopsis plant's roots.

In the largest of the two fossil trunks, above the bulge, the xylem and soft tissue occupied a ring about 50 centimeters in diameter and 5 centimeters thick, with external roots making up the remainder of the 70 - centimeter - diameter tree trunk.

In other trees, notably palms, xylem is formed in strands embedded in softer tissues throughout the trunk.

While snacking, these insects carry the bacterial infection from plant to plant, transferring X. fastidiosa directly into the plant's xylem, the vascular tissues.

The plants referred to as «ferns and fern allies» are plants that have vascular tissue (xylem and phloem for conducting water and sugars), but do not produce fruits and seeds.

The vascular plants (or tracheophytes) are characterized by the presence of vascular tissue (xylem and phloem) for structural support and for long - distance movement of water and nutrients throughout the plant body.

Vascular plants have lignified tissue and specialized structures termed xylem and phloem, which transport water, minerals, and nutrients upward from the roots and return sugars and other photosynthetic products.

Plants transport water in pipe - like structures made of dead and empty cells within a vascular tissue called xylem.
