Functions of roots
absorption
anchorage
produce hormones
Root tip, longitudinal section
root cap
quiescent center
region of cell division
apical meristem
region of elongation
region of maturation
Root Cap
protection
gravity detection
must be renewed (division)
mucigel
Quiescent Center
Not much going on, no cell division
Region of Cell Division
above quiescent center
Apical Meristem
(cells dividing)
protoderm-fewer-outside cells
ground maaristem
procambium-becomes phloem and xylem
Region of Elongation
push cap thru soil
Region of Maturation
unicellular root hairs (only on parts not moving)
Procambium
Part of Apical Meristem
becomes phloem and xylem
Root Cross Section
Epidermis
Cortex-symplastic and apoplastic flow (carries water from out to in)
endodermis
Cortex
Root Cross Section
Symplastic Flow- water goes thru cell
Apoplastic flow- water goes around the cell (faster)
Endodermis
Root Cross Section
water forced thru cell b/c waterproof between cells
Casparian strip-water proof band around cells
Suberin-waterproofing substance
Casparian strip
water proof band around cells of endodermis in root cross section
Subrin
Substance that makes cells water proof (ex, in endodermis of root cross section)
