Splet09. sep. 2024 · The lateral root cap is thought to be involved in the control of the root meristem size (Werner et al 2003). The columella contains statocytes (i.e. gravity perceiving cells). Some basic functions relating to root biology, such as lubrication of root growth and gravitropism, were ascribed to RCs by Haberlandt (1914, reviewed in Barlow 1975). SpletIntroduction.
