Q. Green potatoes are toxic due to :
(a) Solanine
(b) Phytoalexins
(c) Triazene
(d) Hormones
Solution : Correct option : A Solanine is a glycoalkaloid poison found in species of the nightshade family (Solanaceae), such as the potato (Solanum tuberosum) and the tomato (Solanum lycopersicum). Green potatoes have solanine and should not be eaten. When potato tubers are exposed to light, they turn green and increase glycoalkaloid production.
