1, the first day: seed coat cracked

Saw the seed coat cracked when I poured water and saw a white bean.

2. Day 2: Root growth

When I started pouring the water, I saw the root growing out, and the root was growing downward as if it was absorbing water.

3. Day 3: Germs appeared

When I was observing, I saw the germs growing. The pointed white germ grows upwards, absorbing water and carbon dioxide from the air, just as a human being absorbs oxygen.

4. Day 4: Root growth

While observing, I saw that the radicle began to elongate. The embryonic root elongated one or two centimeters and grew into the root of the bean sprout.

5. Day 5: Germ growth

While pouring water, I inadvertently noticed that the radicle was beginning to elongate, burrowing out of the soil and resembling a comma on top of the soil.

6. Day 6: Cotyledons emerge

The cotyledons are a little bit white and a little bit yellow, nice to see. Growing true leaves

7, Day 7: Soybean sprouts now appear

The comma shape of the embryo is gone and grows into leaves and stems, the leaves are green, tender and beautiful, and underneath the leaves are two cotyledons a little yellow. Soybean sprouts are now growing into a seedling, there are four leaves, the stem is about five centimeters, the seedling's roots are very long, there are three or four centimeters. The seedling is green and thick.
