Why Do Stems Grow Towards Light

As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis. … As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis.

What causes plants to grow towards the light?

The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bends toward the light. … This bending toward light is called phototropism. Phototrophism is a response that causes house plants to lean towards the window and trees to branch over the road.

What is the response of stem towards light and gravity?

Stem response to light is positive phototropism (grows towards the light). Root response to gravity is positive geotropism (grows in the direction of the force of gravity).
