Question 1

True or false: Peanuts are nuts, botanically classified as tree nuts like almonds or walnuts.

Accepted Answer

False. Peanuts are legumes, not tree nuts. They grow underground as seeds of a legume plant, related to beans and lentils.

Question 2

True or false: Peanut plants produce yellow flowers that, after pollination, bend down and bury themselves in the soil.

Accepted Answer

True. This process is called geocarpy. The flower stalk elongates and pushes the developing pod into the ground to mature underground.

Question 3

True or false: The peanut plant is native to South America and was first cultivated in Peru over 3,500 years ago.

Accepted Answer

True. Archaeological evidence shows peanuts were grown in Peru around 1500 BCE, making them one of the oldest cultivated crops.

Question 4

True or false: Peanut plants can fix nitrogen in the soil, improving fertility for other crops planted nearby.

Accepted Answer

True. Like other legumes, peanuts have root nodules with bacteria that convert atmospheric nitrogen into a usable form for plants.

Question 5

True or false: Peanut plants are unique in that their fruit develops underground while the flowers are above ground.

Accepted Answer

True. After pollination, the flower stalk (peg) grows downward, pushing the fertilized ovary into the soil, where the peanut pod matures.

Question 6

True or false: George Washington Carver invented peanut butter as we know it today.

Accepted Answer

False. Carver promoted peanuts but didn't invent peanut butter. Ancient Aztecs made peanut paste, and modern peanut butter was patented by Marcellus Gilmore Edson in 1884.

Question 7

True or false: Peanut shells are completely indigestible and have no nutritional value for humans or animals.

Accepted Answer

False. While tough, peanut shells contain fiber and some nutrients. They are sometimes used in animal feed or compost, though not for human consumption.

Question 8

True or false: Raw peanuts contain a toxin that can cause severe stomach upset if eaten in large quantities.

Accepted Answer

False. Raw peanuts are safe to eat; however, they may carry aflatoxin from mold, which is harmful in large amounts. Cooking reduces risk.
