Which part of the tobacco plant is infected by Meloidogyne incognita ?
- Leaf
- Stem
- Root
- Flower
The Correct Option is C
Solution and Explanation
The correct answer is:
Option 3: Root
Explanation:
Meloidogyne incognita, commonly known as the root-knot nematode, primarily infects the roots of plants, including tobacco plants. This nematode causes the formation of galls (swelling) on the roots, which disrupts water and nutrient uptake, leading to stunted growth and reduced yields.
The nematodes enter the roots, causing damage that can make the plant more susceptible to other stresses.
Symptoms include root galls and overall poor plant health.
Therefore, root is the correct answer as it is the part of the tobacco plant infected by Meloidogyne incognita.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Concepts Used:
Applications of Biotechnology
Biotechnology is the technology that utilizes biological systems, living organisms, or parts of this to develop or create different products.
For example, brewing and baking bread fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).
Agriculture
Alternative to conventional farming: A possible solution is the use of genetically modified crops which is an alternative path to conventional farming.
Medicine
In the area of healthcare, recombinant DNA technological processes have made an immense impact which enables the mass production of safe and more effective therapeutic drugs.
Gene Therapy
A collection of methods that allows the correction of a gene defect that has been diagnosed in a child/embryo is called Gene Therapy.
CRISPR technology
For editing genomes, CRISPR is a simple yet powerful tool which allows researchers to easily alter DNA sequences and modify gene function.
