2. Cross Section of Roots Epidermis Protects against water loss
Outer covering Cortex Storage of photosynthetic products Active in
the uptake of water and minerals Pith Centermost region of the root
3. Cross Section of Roots Endodermis Prevents water from getting
into the middle of roots Water can only enter through root hairs
Pericycle Allow for lateral root growth Outermost layer of the
central vascular system 4. Epidermis EndodermisPericycle 5. Cross
section of roots Phloem Carries food from the leaves to the stems
and roots Vascular Tissue Xylem Carries water and minerals from the
root to thestems and leaves Vascular Tissue 6. Monocot Root 7.
Dicot Root 8. Stems - Functions Transportation System Contains
xylem and phloem Support System Holds up leaves and plant 9. Cross
Section of Stem1. Protective Tissues Epidermis & Cork1.
Vascular Tissues Vascular Bundles Includes xylem & phloem 10.
Cross Section of Stem3. Meristematic Tissues Apical meristem (1 -
increase height of plant) Lateral meristem (2 - increase width of
plant) Vascular cambium Produces more xylem towards the insideand
more phloem towards the outside Cork cambium Produces more cork and
cortex 11. Cross Section of Stem4. Storage Tissues Cortex (only
found in dicot stems) Pith (found in both dicot & monocotstems)
