Question

If a seed is inserted upside down into soil, in which direction will its stem and roots grow? Which feature of living thing does this show?

Answer 1

The roots of a seed that is inserted upside down in the soil will grow downwards toward the Earth and the stem will grow upwards away from the Earth. Thus, the direction of growth of roots and stem does not change if a root is inserted upside down in the soil. This feature suggests that all living organisms respond to stimulus. The response in this case is governed by the gravity.
