They also serve as fodder, especially for cattle.
So the correct option is 'Aloe and Trifolium'

The drugs-caffeine, tannin and nicotine are

  1. Alkaloids

  2. Cortisones

  3. Steroids

  4. Mild alkalis


Correct Option: A
Explanation:
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. It is the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world. There are several known mechanisms of action to explain the effects of caffeine. The most prominent is that it reversibly blocks the action of adenosine on its receptor and consequently prevents the onset of drowsiness induced by adenosine. Caffeine also stimulates certain portions of the autonomic nervous system. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term tannin refers to the use of oak and other bark in tanning animal hides into leather. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation, and perhaps also as pesticides, and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of tannins with time plays an important role when determining harvesting times.
Nicotine is an anti herbivory alkaloid and potent parasympathomimetic stimulant found in plants, mostly those in the nightshade family. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine is highly addictive. It is one of the most commonly abused drugs. 
So the correct option is 'alkaloids'.


Which one of the following is an antimalarial drug?

  1. Quinine

  2. Ephedrine

  3. Morphine

  4. Digoxin


Correct Option: A
Explanation:

Quinine in as alkaloid derivative obtained from the bark of cinchona tree. It is used as an anti-malarial drug.

B. Ephedrine is obtained from Ephedra and is used as a sympathomimetic drug.
C. Morphine is obtained from Opium and is used as an analgesic, anaesthetic and sedative.
D. Digoxin is a cardiac glycoside.
Hence, the correct answer is 'Quinine'
