Biology Question on human reproduction
Seeds placed in water imbibe the same because of:
A
(A) Exosmosis
B
(B) Higher Ψω
C
(C) Lower Ψω
D
(D) Pressure of vacuoles
Answer
(C) Lower Ψω
Explanation
Solution
Explanation:
Water potential is the difference in the chemical potential of water in a system over its pure state at the same temperature and pressure. Water potential is represented by the sign Ψω. Water moves from higher water potential to lower water potential. The seeds are dry and have little or negligible water content and hence leading to the entry of water into it. So when placed in water, the seeds imbibe water since the water potential of the seed is lower than that of the surrounding water.Hence the correct option is (C).
