Summary Introduction

To determine:

Whether gravitropism or phototropism is expected to dominate the response of the seedlings in the given picture.

Introduction:

Tropism in plant displays the movement of plant in response to environmental stimuli. Plants usually show their maximum growth towards the water and light because they need these sources for their growth. There are four different types of tropism: phototropism (movement in response to light), gravitropism (towards gravity), thigmotropism (toward mechanical stimulation) and hydrotropism (toward water).
