Which process is used to make plants disease-free using meristem culture? MCQ with Answer and Explanation

Which process is used to make plants disease-free using meristem culture?
A. Tissue culture
B. Mutagenesis
C. Hybridization
D. Cloning
Answer: Option A
Solution (By JKExamLibrary)
Meristem culture, a type of tissue culture, involves excising the virus-free apical meristem (shoot tip) and growing it on a nutrient medium to produce a whole plant free of viruses. This is because meristematic cells lack vascular connections through which viruses spread. Cloning produces identical copies, hybridization crosses varieties, mutagenesis uses mutagens.

Question #1
Which endocrine gland is known as the 'master gland'?
A. Pituitary
B. Thyroid
C. Pancreas
D. Adrenal

Correct Answer: Option A


Explanation:
The pituitary gland, located at the base of the brain, controls other endocrine glands through its hormones (e.g., TSH, ACTH, FSH, LH). Hence, it is called the master gland. The hypothalamus regulates the pituitary via releasing and inhibiting hormones. Thyroid secretes thyroxine, adrenal secretes adrenaline, pancreas (endocrine part) secretes insulin and glucagon. The pituitary has two lobes: anterior and posterior.

Question #2
Consider the following statements about the nitrogen cycle:
1. Nitrogen fixation converts N₂ to ammonia.
2. Nitrification converts ammonia to nitrates.
3. Denitrification returns nitrogen to the atmosphere.
Which of the above is/are correct?
A. 1, 2, and 3
B. 1 and 3 only
C. 1 and 2 only
D. 2 and 3 only

Correct Answer: Option A


Explanation:
All three processes are part of the nitrogen cycle: fixation (N₂ → NH₃), nitrification (NH₃ → NO₂⁻ → NO₃⁻), and denitrification (NO₃⁻ → N₂).

A. Pupil
B. Cones
C. Cornea
D. Rods

Correct Answer: Option B
