Question

In the given flow chart, the flow of water is shown from soil to xylem of the root. Identify the tissues involved in steps A and B.

• A. A–Hypodermis; B–Protoxylem
• B. A–Medullary rays; B–Phloem
• C. A–Endodermis; B–Phloem
• D. A–Endodermis; B–Protoxylem

Answer 1

The correct option is D A–Endodermis; B–Protoxylem

A- Endodermis
B- Protoxylem

Water and minerals are absorbed by the root hairs. From root hairs water travel through the cortex in an apoplastic manner and reaches to endodermis. From here, it travels through pericycle in symplastic manner and then to protoxylem and metaxylem and then it ascends upwards.
