The inside part of the young seed is 7 soft 7 hard

The inside part of the ature seed is 7soft 7hard

A seed is a small em"ryonic plant enclosed with a co#ering called the seed coat.

As the $ruit matures% it seeds also mature. Its co#ering "ecomes hard.A young seed is easier to cut "ecause the inside o$ it is so$t.

A mature seed is more di$$icult to open it "ecause the inside part o$ it is hard.

Inside o$ some mature seeds% you can see a de#eloping plant.
