Why can you know the life and death of seeds by dyeing them with red ink? This is due to the seeds. .............

The plasma membrane of seed living cells is semi-permeable, and living cells have selective permeability. If living cells do not absorb fuel molecules, seeds will not be stained. If it is a dead cell, the cell membrane is completely permeable, and the particles of red ink can freely enter the cell.

You can dye it, so that you can judge the life and death of the seeds.
