Example sentencesExamples
A negative geotropism is a turning away from the earth, such as by a plant stem that grows upward.
An example of negative geotropism would be the main stem.
Geotropism occurs in two forms: positive geotropism to which the root responds by growing downward; and a negative geotropism, which causes the stem to grow upward.
For example, the shoot of a plant has negative geotropism, or response to gravity, but the roots have positive geotropism.
This is called negative geotropism because the plant is growing away from the force of gravity.
