Biology Question on Transport in Plants
Apoplastic movement of water in plants occurs through
A
casparian strips,
B
plasma membrane
C
intracellular spaces
D
plasmodesmata
Answer
casparian strips,
Explanation
Solution
Apoplast pathway is particularly important for water uptake by young corn roots. At the endodermis, water movement through the apoplast pathway is obstructed by the casparian strip. Casparian strip is a band of cradial Cell walls in the endodermis that is impregnated with the wax-like, hydrophobic substance suberin.
