A student reporting on a project said that one of her seeds did not grow properly because it was planted upside down, so it got confused and tried to grow down. Should the teacher accept this explanation? Why or why not?

Expert Solution & Answer

Summary Introduction

To determine:

Weather the explanation is accepted by the teacher or not. Also give reason.

Introduction:

The growth of a plant depends on the gravitropism and phototropism. Auxin is the plant hormone which is important for both gravitropism and phototropism. The seed is planted upside down having same auxin hormones for growth.

Explanation of Solution

Gravitropism is the process which is a directional response to gravity during the growth of a plant. Phototropism is a directional response of plant towards light during growth. Generally, phototropism is experienced by shoots and gravitropism is experienced by roots of plants.

Auxin is the hormone which is synthesized in the shoot apical meristem and travels from shoot to roots within the plants. These hormones help in the cell elongation during growth.

If the seed is placed upside down, then it does not affect the plant growth. The upper part of the seed experiences phototropism and it turns out into the shoot and the lower part experience gravitropism and extracts the nutrients from the soil and it turn out into the roots.

So, the reason given by the student does not justify improper growth of plant. The teacher should not accept this explanation because the growth of the plant is not related with its upside down plantation. Instead, it depends upon phototropism and gravitropism.

Conclusion

As the plant growth depends on sunlight, nutrient source and auxin hormones, so the explanation given by the student is not justified.
