Multiple choice

The pathway of water from the soil through the plant to the atmosphere is

  1. cortex - epidermis - vessel elements - intercellular spaces in mesophyll - stomata - endodermis

  2. epidermis - cortex - Casparian strip - endodermis - sieve cells - intercellular spaces in the mesophyll - stomata

  3. casparian strip - root hairs - epidermis - cortex - xylem - endodermis - intercellular spaces in mesophyll - stomata

  4. root hairs - cortex - endodermis - vessel elements - intercellular spaces in mesophyll - stomata

D Correct answer
Explanation

The correct pathway is: root hairs (absorption) → cortex (through apoplast) → endodermis (via symplast through Casparian strip) → vessel elements/xylem (upward transport) → intercellular spaces in mesophyll (in leaves) → stomata (transpiration). Options A, B, and C all have incorrect sequences or missing steps.
