Have You Ever Wondered...
- Why do you call it an “ear" of corn?
- How many kernels does an ear of corn have?
- How do you make an edible work of art?
“Ear" comes from the ancient word “ahs," which meant “husk of corn." In English, sometimes the ear also is referred to as a “cob" or a “pole."
The ear is the spiked part of the corn plant that contains kernels, the delicious yellow tidbits we love to nibble on in the summertime. Each ear of corn is wrapped in a husk — a green, leafy layer that we peel back before feasting on this summer treat.
Don't feel foolish if you thought an ear of corn had something to do with your ears — you're not alone!
In the 16th century, Italian artist Giuseppe Arcimboldo created a painting he titled “Summer." The painting depicts the bust of a man made from seasonal fruits and veggies: Peapods for lips, a cucumber nose, peach cheeks and — you guessed it — ears of corn!
Check out these kernels of corn knowledge:
- Every row of corn on a corncob has the same number of kernels.
- The average ear of corn has 800 kernels.
- You can find corn in more than 3,000 products on your grocery shelves, including cereal, peanut butter and soft drinks.
- Corn is grown on every continent except Antarctica.
- More than 50 percent of the corn grown in the United States becomes food for livestock.
- The main ingredient in most dry pet food is corn.

你是否曾想過...
- 為什麼你把它叫作玉米”穗”？
- 一穗玉米有多少玉米粒？
- 你如何製作可食用的藝術品？
“穗”這個字來自古英文”ahs”，意指玉米殼。在英語中，有些時候玉米穗也叫作”玉米梗”或“玉米桿”。
玉米穗是玉米植株突起部分上面有我們喜愛在夏日時光啃的美味黃色小吃玉米粒。每一穗玉米被包在一層盡情享用這道夏日盛宴前我們會剝掉的綠色葉狀玉米殼內。
如果你認為玉米穗指的是你的耳朵別覺得蠢—你並不是唯一個這樣想的人。
在16世紀，義大利藝術家朱塞佩·阿爾欽博托繪製了一幅他稱作”夏季”的畫。這幅畫描繪一個用當季水果和蔬菜組成的男人頭像：碗豆當作嘴唇、黃瓜當作鼻子、水蜜桃當作臉頰和—你猜到的—玉米穗耳朵！
看看這些玉米粒知識：
- 一根玉米梗上的毎一列玉米有相同的玉米粒數量。
- 玉米穗平均有800顆玉米粒。
- 你可以在你的雜貨架上發現超過3,000種玉米產品，包括穀物食品、花生醬和軟性飲料。
- 除了南極圈外玉米生長在所有大陸。
- 美國生長的玉米有超過五成作成家畜的飼料。
- 大多數的寵物乾飼料主要成份是玉米。
