Mustard Cress Update

What happened to the seeds?
Plants grew out of them. We can see shoots and roots.
The seeds split and the plants came out.

The shoots aren't all green. Some of the shoot is white.
The roots are white. They have hairs coming out. The roots are trying to get the water.
There are 2 leaves at the top. They are green on one side and purple on the other.

Next we think the plants are going to grow some more. They might get some more leaves. They might get bigger, like trees. The leaves might get bigger. The shoot might turn all green.
