They can't rely on diffusion alone
Too active
Small surface area to volume ratio
Multicellular
Water
Inorganic substances
Organic nutrient
Transpiration
Translocation
Xylem in the middle and phloem outside
Seperate vascular bundles around a medula
Forming a central midribi
Active transport
Diffusion
Osmosis
Symplast pathway
Apoplast pathway
Vacuolar pathway
Cellulose
Water filled spaces
Cytoplasm
Oxygen
Apoplast
Symplast
Waxy cutile
Fibres
Suberin
Elongated cells
Isodimetric
No cholorplast
Support vessels
Transport water
Packing tissue
Because they have no nucleus
Lignin is impermeable
Just because
The movement of water up the xylem using osmosis
The loss of water vapour from areal parts of the plant due to evaporation
It enables a transpiration stream
Aids translocation
Cooling effect
