Question 1

True or false: The peanut plant produces nuts that are 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: 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 3

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 4

True or false: George Washington Carver used the peanut plant to invent peanut butter as we know it today.

Accepted Answer

False. Carver promoted many uses for peanuts, but he did not invent peanut butter. Ancient Aztecs made a paste, and the first modern peanut butter patent was by Marcellus Gilmore Edson in 1884.

Question 5

True or false: Peanut plants produce flowers above ground, but after pollination, the fruit develops underground.

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: Peanut plants produce yellow flowers; after pollination, a peg grows from the flower and pushes the developing pod into the soil.

Accepted Answer

True. After pollination, the flower stalk (peg) elongates and pushes the ovary into the ground, a process called geocarpy.

Question 7

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

Accepted Answer

False. Raw peanuts do not naturally produce a toxin; they contain anti-nutrients but not a severe toxin. Harmful aflatoxin from mold contamination may be present, but that is not from the plant itself.

Question 8

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.
