Solution

This statement is true.

Explanation:

Yes, it is true that soaked seeds burst into three seed coat layers for germination. In some plants, the surface layer, middle layer, and inner layer make up a three-layered seed coat. So, when they are soaked in water, water is imbibed into the seeds and the seeds swell up, exerting pressure on the seed coat and burst the seed coats.
