protects
the
root

grows through
the
ground
Epidermis
is a layer of cells that covers the rest of the
root
Root
hair
provides
anchorage
to the plant and takes in
water
from the
soil
Water
and
mineral ions
(
salt
) are absorbed by
root hairs.
Cytoplasm
inside of
root hair cell
contains lots of
dissolved molecules
including
sugars
and
salt
Osmosis
is the process by which the
roots
absorb
water
Water
moves by
osmosis
Minerals move by
active transport
Active
transport
is a process by which the
roots
absorb
mineral ions
Xylem
transports
water
,
minerals
and
organic
compounds such as
amino acids
and
sucrose
Xylem
is a type of vascular tissue that transports
water
and
dissolved minerals
from the soil by the
roots
to the rest of the plant
Xylem vessels
are long, thin, hollow tubes made up of
dead cells
Phloem
, also called
bast
, transports
assimilate
(substances made by the plant) from the
source
Phloem
carry sugars (in
sap
) from
leaves
to the rest of the
plant
