Q: What is phototropism?
Solution:
Phototropism is the growth of a plant towards light, driven by auxin distribution.
Steps: 5
Show Steps
Step 1: Understand that phototropism is a term used to describe how plants grow.
Step 2: Know that plants grow towards light sources, which is called phototropism.
Step 3: Learn that a special hormone in plants called auxin helps control this growth.
Step 4: Realize that auxin moves to the side of the plant that is away from the light, causing that side to grow faster.
Step 5: As a result, the plant bends towards the light because the side with more auxin grows longer.
