Take a peek at these seeds! I took some photos of Fast Plants seed as they germinated. Normally our observations of the Fast Plants start when they emerge from the soil on about day three. Here are some photos of the seeds growing on a water mat. They give you a glimpse of what is going on under the soil.
Look for the seed coat to split open. Look for for the root to emerge from the seed. Check the pictures to see when the stem beginning to push up out of the seed away from the root. Can you tell at what point the plant would have come up out of the soil?

Wait! Do you know what I wonder? How does the root know which direction to grow? How do the stem and seed leaves know which way is up? It would be dark under the soil so they are not turning toward the light - how does the root know which way to go to find more soil and how does the stem know which way to go to find light?
