Answer 1

Textbook Question

Chapter 40, Problem 1U

Which of the following is stimulated by blue light?

a. Seed germination

b. Detection of plant spacing

c. Phototropism

d. Shoot elongation

Expert Solution & Answer

Summary Introduction

Introduction:

The white light consists of the seven colors “violet”, “indigo”, “blue”, “green”, “yellow”, “orange”, and “red”. The blue color of the light has the wavelength equal to 460 nm (nanometer).

Answer to Problem 1U

Correct answer:

The phototropism is stimulated by the blue light. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

The direction of the feedback of the plant organs either in the direction of the light source or away from the light source is called phototropism. The blue light receptors are present on the plant organs, which direct the phototropism.

Option c. is given as “Phototropism”.

As, “the blue light influences the movement of plant organs, the plant organs in most of the cases show the positively phototropic movement”, it is the right answer.

Hence, option c. is correct.

Reasons for the incorrect statements:

Option a. is given as “Seed germination”.

The seed germination does not require the presence of light, as the seed germinates beneath the soil. So, it is a wrong answer.

Option b. is given as “Detection of plant spacing”.

The detection of the plant spacing is related to the far-red light exposure. This is not related to the blue light stimulation. So, it is a wrong answer.

Option d. is given as “Shoot elongation”.

The elongation of the shoot is regulated by the presence of a pigment, which is blue green in color. So, it is a wrong answer.

Hence, options a., b., and d. are incorrect.

Conclusion

The parts of the plants move positively from the stimulation by the blue light.
