Why seeds imbibe and swell after keeping in water? |
|
|
1) |
OP inside the seed is low |
|
2) |
OP of water is high |
|
3) |
Water potential gradient developes between the seed coat and water |
|
4) |
Diffusion pressure deficit of seed is very high |

The imbibants have negative water potential. As a result when they come in contact with water, a steep water potential is established between the imbibant and imbibate
