Unlike animals, plants lack a metabolically active pump like the heart to move fluid in their vascular system. Instead, water movement is passively driven by pressure and chemical potential gradients. The bulk of water absorbed and transported through plants is moved by negative pressure gener...
Starting with a pool cantilevered above the rooftop, the water alternately flows out in waterfalls or rains down, passing through a series of interior channels and watering hanging plants through artificial rainfall. The water ultimately finds its way to an indoor waterfall, which plummets into an...
Controlling plants’ growth at this level is exciting, but actually putting it into practice is not an easy task. At the moment, Brophy is testing the method in the lab using a small weedy plant called Arabidopsis. She’s still in the process of figuring out how to activate certain genes...
Water Movement Xylem tissue is nonliving, so water moves from bottom to the top of the plant using mechanical methods. Although how the xylem works isn't perfectly understood, two mechanisms seem to be involved. Leaves constantly lose water through a process called transpiration. As water evaporat...
PATHOGENS causing vascular wilt diseases grow in the xylem tissues of their host and induce severe wilting of the foliage, possibly by causing an impediment in the movement of water in the xylem1,2. Measurements of water flux through stem segments have i
Water transport in trees is ensured by the passive movement of water through capillary pipes in the xylem called conduits. Depending on species, these conduits vary in width, length, and connection with each other. Coniferous tree species possess tracheids only, which are elongated, individual cell...
Water can collect into bodies of water through something called runoff. This is where water flows over land in a sort of unofficial stream until it goes into a larger body of water. During this stage of the water cycle, plants also uptake water through their roots. Percolation also takes ...
The evaporative loss of water from plants is called transpiration, and this process is important for transport of substances within the plant as well as for evaporative cooling of leaves. We will now look at the pathways for water movement from the soil through the plant to the atmosphere and...
