Question

Identify the correct sequence of movement of water in the root of higher plants.

• A. Epidermic - Cortex -Pericycle-endodermis - phloem
• B. Epidermis -Cortex-endodermis -pericycle -phloem
• C. Epidermis -Cortex -pericycle-endodermis -xylem
• D. Epidermis -Cortex-endodermis-pericycle -xylem

Answer 1

The correct option is A Epidermic - Cortex -Pericycle-endodermis - phloem

Water will take the path of least resistance through root to reach the xylem. Water can move across the root via three different pathways. Once in the endodermal cells, the water freely enters the xylem cells where it joins the fast-moving column of water or transpiration stream, headed to the leaves.

So the correct option is 'Epidemic - Cortex -Pericycle-endodermis - phloem'.
