In plant xylem tissue, there are two types of cells involved in the actual movement of water, tracheid and vessel elements. For tracheid elements, think of the human trachea, ...

This advanced technology can detect a reduction in acidity in plant xylem tissues, providing early warning of drought stress in plants up to 48 hours before traditional methods.

Xylem is the porous tissue that conducts fluid in plants. In woody plants, it is called sapwood. Surrounded by bark, it often surrounds older, inactive heartwood itself.

Owing to recent advances, plant vascular developmental can now be described from early specification during embryogenesis up to late differentiation events. Plant vascular tissues display both ...

The plant's problem is something called cavitation, or the growth of air bubbles, which makes it harder for water to reach the leaves. But Karnik says xylem has a way of getting rid of these bubbles.

The green world that we live in would not have been possible without hidden changes to the plant body over the last 400 million years. To grow beyond just centimeters tall outside of the wettest ...

Karnik's sapwood filters harness the hardware already built into plant tissue. In transit from plant's roots to its leaves, water bounces through a meshwork xylem, a series of conduits and ...

But smaller-scale tweaks to xylem cells and tissue organization can protect against drought, too, says Cornell University evolutionary biologist Jacob Suissa, who was not involved in the new study.

It is through two kinds of elements of xylem tissue called, xylem vessels and tracheid that water and minerals move from roots of a plant to its leaves. Xylem vessels Xylem vessel is a long tube ...
