An additional apoplastic route that allows direct access to xylem is along the secondary roots because they ______.

Options

  1. Ado not pass through endodermis
  2. Bhave plasmodesmata
  3. Cdevelop from pericycle
  4. Dare made up of non-living cells

Correct answer

C. develop from pericycle

Step-by-step solution

Secondary roots (lateral roots) originate from the pericycle, which is a layer of cells located just inside the endodermis. As these secondary roots grow outward, they break through the endodermis and its Casparian strip. This disruption creates a gap in the endodermal barrier, providing an additional apoplastic route that allows water and solutes direct access to the xylem, bypassing the Casparian strip. Answer: develop from pericycle
