Question

Mutations in plant cells can be induced by

• A. Zeatin
• B. Kinetin
• C. Infrared rays
• D. Gamma rays

Answer 1

The Correct Option is D

To determine which option induces mutations in plant cells, let's examine each choice:

1. Zeatin: This is a type of cytokinin, a class of plant hormones that promote cell division in plant roots and shoots. Zeatin does not induce mutations.
2. Kinetin: Another cytokinin, similar to zeatin, that regulates cell growth and plays a role in various plant developmental processes. Kinetin, like zeatin, does not cause mutations.
3. Infrared rays: These are part of the electromagnetic spectrum, with wavelengths longer than visible light. Infrared rays do not have enough energy to cause changes at the genetic level, so they do not induce mutations.
4. Gamma rays: This is a high-energy form of electromagnetic radiation. Because of their high energy, gamma rays can penetrate cells and cause damage to DNA, leading to mutations. Gamma rays are often used in research to induce mutations for studying genetic functions and breeding purposes.

Therefore, the correct answer is Gamma rays because they have the energy required to alter the DNA structure in plant cells, leading to mutations.
