(d) Water is absorbed by germinating seeds through the process of imbibitions and helps in rupturing of seed coat. Imbibition is the process of absorption of water by hydrophilic surface of a substance without forming a solution. It is a type of diffusion by which movement of water takes place along a diffusion gradient. During the process of imbibitions, volume of imbibant is changed, heat is produced and imbibitional pressure is developed. |
