The movement of water through the apoplast pathway does NOT cross which layer in the root?

Question

Team JKSSB Mock Tests · Accepted Answer

In the apoplast pathway, water moves through cell walls and intercellular spaces without crossing membranes. However, at the endodermis, the Casparian strip (suberin deposition) blocks apoplastic movement, forcing water to enter the symplast (via plasma membrane). Thus, apoplastic movement stops at the endodermis. This ensures selective uptake of minerals.
