Evaluating symplast and apoplast pathways in plants

Steps:

• Define symplast pathway: continuous cytoplasm linked by plasmodesmata, allowing water to pass directly through these channels between cells.
• Statement 1 is false because water moves through plasmodesmata in symplast.
• Define apoplast pathway: extracellular route via cell walls and intercellular spaces, bypassing cell membranes.
• Statement 2 is false because water flows through intercellular spaces in apoplast.
• Casparian strip: waxy band in root endodermis that seals cell walls, blocking apoplast flow and redirecting to symplast.
• Statement 3 is true as it accurately describes the Casparian strip's role.

Why none of the options is correct:

• Only statement 3 is accurate; options A–D all include at least one false statement (1 or 2).

Final answer: None of the options
