The Xylem cells are basically transport cells that act like a highway for the water to travel to its necessary areas. They are long empty tubes tightly fitted together and joined end to end, containing lignin that prevents them from collapsing.
it is drawn up by transpiration

Dosent it move by the cohesion tension theory?
when water is pulled up through the xylem by an attraction of water to the tissue
A xylem cell will carry water using the elongated cells that it is made up of. The xylem is the organ that will distribute water and nutrients in the plants.
As water moves out of a leaf, more water moves up through the xylem.
The movement of water provides a simple mechanism for feeding respiration circulation and excretion.
transpiration is the process that moves substances through the xylem
convection
Osmosis is the movement of water across the cell membrane or the movement of water through diffusion. :)
its not homeostasis
The vasculature inside the green leaf moves a number of particles of food, water, minerals and gases.
Osmosis is the term used to describe the movement of water through cells. Osmosis is important because all cells need water in order to survive.
A movement of water cause by currents and wind.
through the mechanism of garvity and density difference
Water and food particles are drawn in through one siphon to the gills where tiny, hair-like cilia move the water, and the food is caught in mucus on the gills
Osmosis.
