How plants absorb water?
How water gets into plants?
Osmosis
Natural movement of water molecules from an area of high concentration
When soil is moist contains
a higher concentration of water molecules
Water moves from the soil
through the root’s outer membrane
into root cells.
How water travels up a plant?
Eventually, the water is squeezed out into the surrounding space
eventually, the water is squeezed out into the surrounding space
it enters xylem vessels at the centre of the root.
delivering sap (water and diluted mineral nutrients) around a plant.
Transpirational pull
delivering sap (water and diluted mineral nutrients) around a plant.
as water is cohesive and adhesive it moves up through the plant as a continuous column
How plants absorb water in different soil types?
The proportions of sand, clay and silt
dictate the size and number of pores a soil contains
Soil pores
are the gaps between soil particles in which water or air is held.
What about fluctuating moisture levels?
What happens when there is too much or too little water?
To little
interrupt the channel of water moving up through a plant
water stressed plants
Slow and stunted grow
Poor or no flowers
Unidersized fruit
premature leaf drop
increase in pest and disease problems
Halt the delivery of vital nutrients and other molecules to cells
