Summary Introduction
Introduction:
The entering of water and dissolved solutes into the root takes place through root epidermis. The mechanisms used are symplast and majorly the apoplast. In the apoplastic mechanism, water usually moves through the nonliving regions, while in the symplast, water passes into and through the living cells. In apoplastic, water moves inward till endodermis. Endodermal cells are tightly pack and have lignified casparian belt.
