Question 1

True or false: Edamame plants can fix nitrogen in the soil through a symbiotic relationship with bacteria.

Accepted Answer

True. Like all legumes, edamame (immature soybeans) form root nodules with Rhizobia bacteria, converting atmospheric nitrogen into a plant-usable form.

Question 2

True or false: Eating raw edamame is perfectly safe and even more nutritious than cooked.

Accepted Answer

False. Raw edamame contains lectins and trypsin inhibitors that can cause digestive upset. Cooking neutralizes these compounds and makes nutrients bioavailable.

Question 3

True or false: Edamame is harvested after the soybean pods have fully dried on the plant.

Accepted Answer

False. Edamame is actually harvested while the pods are still green and immature, before they harden and dry. Dried soybeans are a different product.

Question 4

True or false: Edamame is a genetically modified crop that cannot be grown from saved seeds.

Accepted Answer

False. Most edamame varieties are non-GMO and can be grown from saved seeds, though hybrid varieties may not breed true. GMO soybeans are mainly for oil.

Question 5

True or false: Edamame plants are short-lived perennials that can produce pods for multiple years.

Accepted Answer

False. Edamame is an annual plant, completing its life cycle in one season. It must be replanted each year to get a new harvest.

Question 6

True or false: Edamame pods contain more protein per gram than beef steak.

Accepted Answer

True. Edamame has about 11g protein per 100g, while cooked beef steak has around 26g. But by calorie, edamame is higher—so per gram, it's surprisingly protein-dense.

Question 7

True or false: Edamame leaves can detect and respond to touch by releasing a citrus-like scent.

Accepted Answer

True. Soybean leaves have tiny hairs that release a chemical compound (similar to green leaf volatiles) when brushed, giving a fresh cucumber-citrus smell.

Question 8

True or false: Edamame plants produce tiny, self-pollinating flowers that rarely need bees for pollination.

Accepted Answer

True. Soybean flowers are perfect (both male and female) and typically self-pollinate before opening, so bees aren't required, though they may visit.
