Connexus 2.6 7th grade, Item 8: A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?

Answer 1

The correct pair of tropisms that describe the observed responses of a plant having deep roots and tendrils that wrap around objects are:

1. Geotropism: Geotropism refers to a plant's response to the force of gravity. In this case, the deep roots of the plant indicate a positive geotropism, as they grow deeper into the ground in response to the force of gravity.

2. Thigmotropism: Thigmotropism refers to a plant's response to touch or contact with objects. The tendrils of the plant wrapping around objects indicate a positive thigmotropism, as they are growing and clinging to the objects they come into contact with.
