What areas (zones) can be distinguished by considering a young root?

1. What areas (zones) can be distinguished by considering a young root? 2.What is the significance of the root cap? 3. Where is the cell division zone? How are its cells different from the cells of other zones? 4. Where is the root elongation zone located? What is its meaning?

The structure of a young root forms 4 zones of its structure: division, growth, absorption and conduction. The root cap is the outer layer of cells that covers the root, providing a protective function. The division zone is a zone of constant mitotic division. Down it forms a cap, up – a growth zone. In the latter, structures are enlarged, filled with vacuoles. In the process of plant life, permanent root tissues are formed from them.
