In "two weeks time to seedling", the root will curl down, and the stem will curl up.

Explanation:

In normal tropical climate, the seeding time for a healthy seed is less than two weeks. With regular and optimum watering after sowing the seed, curling up of the stem and curling down of the roots would naturally happen within two weeks of time. The curling time of the stem and the roots also depends on how deep inside the soil has the seed been sown.
