of the Root of a Typical
Function of Roots:
a. Anchors plant in ground.
b. Absorbs water & minerals.
c. Storage of food made by leaves.
Hairs: Outward extensions of epicermal cells which extend between
soil particles to collect water and solutes (minerals).
Region of Maturation: Older section
of root tip where the root begins adding cells to increase the width, and where
root hairs form.
Region of Elongation: Region of
root tip where cells get longer, thus lengthening the root. This is the only
place where the root grows longer.
Region of Rapid Growth: Region where
cells divide rapidly by mitosis.
Apical Meristem: Cells near the
tip that can divide by mitosis to make any type of plant cell.
Root Cap: Dome-shaped mass of cells
at the tip which protect the meristem cells from damage (as root extends through
