If the root cap is removed, root growth ceases to respond to gravity. The root cap is vital for gravitropism since it contains cells with sensors called statoliths, which are amyloplasts packed with starch.
root cap - a sheath of cells that protects the meristem from abrasion and damage as the root tip grows through the soil.
Although slicing the onion root captures many cells in different phases of the cell cycle, keep in mind that the cell cycle is a continuous process.
The very tip of the root is covered by a protective, thimble-shaped root cap. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells. Some of the cells produced...
