Why Do Plants Sometimes Elongate Towards One Direction?

Unit 6 Discussion Forum

In your readings, you learned about how plants respond to a variety of environmental stimuli including light, gravity and even touch.

Question 1: Select a specific example of how a plant responds to stimuli

Introduction:

Phototropism- an elongation towards one side.

Hello classmate. As we studied this week, one thing that resonated with me is the plants responses to light, which is called phototropism- an elongation or growth towards or away from light source. One-sided growth. Wow, this is very interesting because all my life I have asked this very question, why do plants sometimes elongate towards one direction? Hold it, not only plants, even humans. I have seen many people growing in one direction, sometimes growing only and only

I made a potatoes garden in my house. Close to my garden was a big tree that prevented my garden from receiving sunlight. However, I was happy seeing my potatoes growing and growing looking for sun light. To my greatest surprise during harvest, I got nothing. I thought my potatoes garden was bewitched. Now I know better, it was IAA. It will never happen again.

Question: 3 How is this response an adaptation for the plant?

Survival. Survival mechanism to get sun light needed for photosynthesis, which brings more energy to the plant. “Since plants must make their own food to survive (by changing light energy into chemical energy—a process called photosynthesis), the ability to capture as much of this light energy as possible is crucial to its survival, “(Science clarified, 2017, p.7).

We humans when need something we move around and take what we need. Very unfortunate for plants. They cannot move from one place to another. So phototropism is the only way plants can adjust to their environment and go all out for what they needed for survival, if they are not getting enough.
