Answer:
paracrine signaling.
Explanation:
Chemical signaling between cells is one of the most important ways that activities of tissues and organs are coordinated. The nervous system is the other major coordinating system in animals, but even here chemical signaling is used between adjacent neurons. The mechanisms involved are described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or pheromones. Paracrine signals diffuse locally and act on neighboring cells.

Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.
Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is absorbed root hairs by the process called active transport.
The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
