Question

Green potatoes are toxic due to
A. Phytoalexins
B. Solanine
C. Triazine
D. Hormones

Answer 1

Hint: Toxic is any enzyme or substance which is very poisonous or something which is harmful and bad. A Poison that will cause you to become ill is described as toxic.

Complete answer:
The potato is a root vegetable native to the Americas, a starchy tuber of the plant Solanum tuberosum, and the plant itself is a perennial in the nightshade family, Solanaceae.
Nowadays, they are a staple food in many parts of the world and an integral part of much of the world's food supply.

Potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice. Potatoes contain two kinds of glycoalkaloids both are natural toxins known as solanine and chaconine.
Both solanine and chaconine cause toxicity through cell disruption leading to gastrointestinal symptoms such as vomiting, abdominal pain, and diarrhea.

- Phytoalexins: It is a substance that is produced by plant tissues in response to contact with a parasite and specifically inhibits the growth of that parasite.

- Solanine: It is one of the glycoalkaloids which is naturally toxic.
It causes toxicity through cell disruption which leads to GIT problems including vomiting, abdominal pain and diarrhea.

- Triazine: Triazines are nitrogen containing heterocycles.
It is a heterocyclic structure that contains three nitrogen atoms and three carbon atoms.
Hormones: They are chemical messengers that are secreted directly into blood, which carries them to organs and tissue of the body to exert their functions.

Hence, The correct answer is option (B).

Note: Toxic alkaloid is part of the plants' defense mechanism, making them unappealing to animals tempted to munch on them. All parts of the plant contain solanine, but the heaviest concentrations tend to be in the leaves and stems.
Tomatoes have a long, somewhat shady, history due to their association with nightshade.
