Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Assertion:Water and mineral uptake by root hairs from the soil occurs through apoplast until it reaches endodermis.
Reason:
Casparian strips in endodermis are suberized.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
In
plants, usually maximum water uptake is found in the root hair zone, as
this part has the maximum surface area due to the presence of root
hairs. These root hairs also withdraw from interspaces, which are not in
contact with epiblema of the root. Whereas, the zone of mature cells
cannot absorb water because of the presence of impermeable and suberised
surface layer.
