Root caps contain statocytes which are involved in gravity perception in plants. [1] If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants. [1] The general zones of the primary root (taproot) that gives rise to eventual lateral roots are presented below from top to bottom. The most mature and developed tissue is found near the top, while the newly dividing cells are found near the bottom. Maturation Zone: Cells in this stage have developed differentiated characteristics and have completed maturation and elongation. The xylem system is seen to develop in this zone along …
