Question 15 (1 point) Which of the following demonstrates positive phototropism? bean plants twisting around a bean pole 12 a ho

Pavlova-9 [17]

Given what we know, we can confirm that among the options listed, the more appropriate example of positive phototropism is the houseplant growing towards the window.

<h3>What is positive phototropism?</h3>

This is a photosensitive reaction that occurs in plants.
Positive phototropism is described as the growth of plants towards the source of light.
While negative phototropism is when the plants lean away from the light.
Sunflowers and bananas, which lean towards the sun as they grow, are prime examples of positive phototropism.

Therefore, given the definition of positive phototropism as the growth of an organism towards a source of light, we can confirm that the option stating that the houseplant grows towards the window is the best example of this concept, given that the window is the source of light for the plant.
