Root hair cells
Cells on the roots of plant that increase the surface area for maximum absorption of water and mineral ions
1 of 14
Transpiration
The loss of water of a plant through the stoma of leaves
2 of 14
Water potential
How much the water is pure (pure = 0)
3 of 14
Appoplast pathway
When water moves round the cell walls of plant
4 of 14
Symplast pathway
When water moves Straight through the cells (by diffusion)
5 of 14
Cohesion
Water molecules stick/cohese together up the walls of the stem
6 of 14
Osmosis
The movement of water only, from an area of high water potential to an area of low water potential
7 of 14
Casparian Strips
These are waterproof, causing the appoplast pathway to be forced through the cell - joining the symplast pathway
8 of 14
Plasmodesmata
extension bridges -speeds up
9 of 14
Root pressure
Water moving into the roots by osmosis causing pressure, pushing water up the stem.
10 of 14
Cortex
supportive tissue/padding cells
11 of 14
Phloem
food - sugars/minerals transport system
12 of 14
Xylem
Water transport system
13 of 14
Transpiration pull
When water evaporates from the leaves, it pulls the water that it is cohesed with it, which pulls water further up the stem.
