GEOTROPISM LIMA BEAN

How Do Roots Grow When the Direction of Gravity Changes
How Do Roots Grow When the Direction of Gravity Changes? Geotropism (also called gravitropism) is the directional growth of an organism in response to gravity. Roots display positive geotropism when they grow downward, while shoots display negative geotropism when they grow upward.

Caroline wants to design an experiment to determine the effects of geotropism on the roots of lima bean sprouts. She plans on having a control group and an experimental group. A good design would involve. positioning the experimental sprouts in different orientations relative to the Earth.

and Phototropism of Lima Bean Seedlings?
The cause of phototropism is an auxin. Auxin is a hormone that tells the side of the plant with the most shade to grow longer than the other side. This causes the plant to bend toward the light source. (Modified from Purves, 2001) Lima Beans - Lima beans were first grown around Lima, Peru about 6,000 B.C.

Phototropism Experiments | Sciencing
Phototropism in plants refers to the direction of plant growth in relation to a light source. Positive phototropism is growth towards a light source. Negative phototropism is growth away from light. These phenomena are easily observable through phototropism experiments that anybody can do.
Plants on the Move! Experiments with Phototropism
Figure 1. This diagram depicts early experiments with phototropism. Darwin showed that the phototropic response was lost when the tip of the emerging plant was cut off or covered with an opaque cap.
