8.1 Xylem & Phloem

Why do plants need water?
> keeps plant r__
> t__ of minerals
> keeps plant c__
> allows chemical r__ in cells
> provides m__

rigid, transport, cool, reactions, minerals

Veins (v__ b__)
> made up of x__ & p__

vascular bundle, xylem, phloem

Xylem
> transports w__ & m__ in only __ direction
>> r__ → l__
> are joined together, w/ no c__ inside
> walls are thickened by __

water, minerals, 1, roots, leaves, cells, lignin

Phloem
> transports s__ & a__ a__ in __ directions
> sucrose made in the l__ (via photosynthesis) moves __ the plant
> sucrose stored in the r__, t__, stems moves __ the planet

sucrose, amino acids, both, leaves, down, roots, tubers, up
