Pole beans need something to grow around and up. Which kind of stimuli can encourage this type of growth? does it need touch, water, gravity, or light
without something to grow on
Pole beans need something to grow around and up, such as trellises, poles, or strings. The type of stimuli that can encourage this upward growth is primarily touch or physical support. When the bean plants come into contact with a structure or support, they will naturally begin to wrap their tendrils around it and climb upward.
While water, gravity, and light are essential for the overall growth and health of the plants, they are not direct stimuli for the climbing behavior of pole beans. However, sufficient water and light are still required for the beans to grow strong and healthy stems and leaves, which can then support their climbing behavior.
In summary, pole beans require physical support provided by structures like trellises and poles to encourage their upward growth, while water and light support their overall development.
