Step 1: Understanding imbibition.
Imbibition is the process by which seeds absorb water during germination. It involves the movement of water into the seed through the cell walls and membranes.
Step 2: Analyzing the options.
(A) endosmosis: Incorrect, endosmosis is the movement of water into the cell, but imbibition is the more specific term for seed germination.
(B) osmotic pressure: Incorrect, osmotic pressure drives water movement but is not the specific process in seed germination.
(C) exosmosis: Incorrect, exosmosis refers to the movement of water out of cells, not absorption during germination.
(D) imbibition: Correct, imbibition is the process by which seeds absorb water.
Step 3: Conclusion.
The correct answer is (D) imbibition, as this is the process that facilitates water absorption in seeds.
