Introduction to Corn Anatomy
To appreciate the significance of the head of corn, it’s vital to understand the basic anatomy of the corn plant. Corn, also known as maize, is a type of cereal grain that belongs to the grass family. The corn plant consists of several key components, including the roots, stem, leaves, and the ear, which is the part that produces the corn kernels. The ear is made up of the cob, kernels, and the husk, which is the outer covering that protects the kernels.
The Ear of Corn: A Closer Look
The ear of corn, also known as the cob, is the female reproductive part of the corn plant. It’s a cylindrical structure that contains the kernels, which are the seeds of the corn plant. The ear is covered with a protective layer of leaves called the husk, which helps to shield the kernels from damage and disease. The ear is attached to the corn plant by a stalk, and it’s typically around 6-10 inches long, although some varieties can be longer or shorter.
Parts of the Ear
The ear of corn is composed of several distinct parts, including the cob, kernels, and the tip. The cob is the hard, inedible core of the ear, while the kernels are the soft, edible seeds that surround the cob. The tip of the ear is the pointed end, where the kernels are typically smaller and less developed. The ear also has a series of rows, which are the horizontal lines that run along the length of the ear, containing the kernels.
The Head of Corn: Terminology and Characteristics
Now that we’ve explored the anatomy of the corn plant and the ear, let’s focus on the head of corn. The head of corn is also known as the ear or the cob, and it’s the part of the plant that produces the corn kernels.

What is the head of corn called?
The head of corn is commonly referred to as the ear of corn. This is the part of the corn plant that contains the kernels, which are the edible seeds that we harvest and consume. The ear of corn is the mature ovary of the corn plant, and it is typically covered in a protective layer of leaves called the husk. Inside the husk, the kernels are arranged in rows on a central core called the cob.
The ear of corn is a unique and fascinating structure, with each kernel containing a tiny embryo of a new corn plant. The kernels are connected to the cob by a short stalk, and they are nourished by the plant’s vascular system. As the corn plant matures, the kernels fill with starch and other nutrients, eventually becoming the delicious and nutritious food that we know and love. Whether you enjoy it on the cob, in a salad, or as a sweet and crunchy snack, the ear of corn is an amazing and versatile part of the corn plant.
What is the purpose of the husk on an ear of corn?
The husk on an ear of corn serves several important purposes. Firstly, it protects the delicate kernels and cob from damage and disease. The husk is a tough, fibrous layer that shields the ear from insects, birds, and other pests that might try to feed on the kernels. It also helps to retain moisture and regulate the temperature of the ear, creating a stable environment for the kernels to mature. Additionally, the husk helps to prevent the ear from drying out, which can cause the kernels to become brittle and prone to breakage.
As the corn plant grows and matures, the husk begins to dry out and turn brown. This is a natural process that signals the ear of corn is ready to be harvested. The husk can be removed to reveal the delicious kernels inside, or it can be left on to help preserve the ear and keep it fresh. In some cases, the husk is also used as a natural wrapping material, such as when grilling or roasting ears of corn. Overall, the husk is a vital part of the ear of corn, playing a crucial role in its development and protection.
How do corn kernels develop on the ear of corn?
Corn kernels develop on the ear of corn through a process called pollination. As the corn plant matures, it produces both male and female flowers. The male flowers, which are located at the top of the plant, produce pollen that is carried by the wind to the female flowers, which are located on the ears of corn. When a pollen grain lands on a female flower, it fertilizes the ovary, causing the kernel to begin developing. Over time, the kernel grows and matures, filling with starch and other nutrients.
As the kernels develop, they are arranged in rows on the cob, with each row containing multiple kernels. The kernels are connected to the cob by a short stalk, and they are nourished by the plant’s vascular system. As the corn plant continues to grow and mature, the kernels fill out and become plump, eventually forming the delicious and nutritious ear of corn that we harvest and eat. The entire process, from pollination to maturity, can take several months, depending on factors such as weather, soil quality, and the specific variety of corn being grown.
What is the difference between sweet corn and other types of corn?
Sweet corn is a specific type of corn that is bred for its high sugar content and tender kernels. It is harvested when the kernels are immature and the sugar content is at its highest, typically within a few days of pollination. Other types of corn, such as dent corn and flint corn, are harvested when the kernels are mature and dry, and are often used for animal feed, ethanol production, or other industrial purposes. Sweet corn, on the other hand, is meant to be eaten fresh, and is often enjoyed on the cob, in salads, or as a side dish.
One of the key differences between sweet corn and other types of corn is the way it is processed. Sweet corn is typically harvested by hand, and the ears are removed from the plant with a small portion of the stalk attached. This helps to preserve the delicate kernels and prevent them from becoming damaged or bruised. Other types of corn, on the other hand, are often harvested using mechanical combines, which can be more efficient but also more damaging to the kernels. Overall, the unique characteristics and harvesting methods of sweet corn make it a delicious and popular treat that is enjoyed by people all over the world.
Can you grow corn at home, and if so, how?

With proper care and attention, you can enjoy a delicious and rewarding harvest of fresh corn from your own backyard. Whether you have a large garden or just a small patio, growing corn at home can be a fun and rewarding experience that provides you with fresh, healthy produce and a sense of accomplishment.
How do you know when an ear of corn is ready to be harvested?
An ear of corn is ready to be harvested when the kernels are fully mature and the husk has begun to dry out. This is typically around 3-4 months after planting, depending on the variety and growing conditions. To check if an ear of corn is ready, you can pull back the husk and look at the kernels. If they are plump and creamy, and the liquid inside is milky, then the ear is ready to be harvested. You can also check the color of the husk, which should be a light brown or tan color when the ear is mature.
As you harvest the ears of corn, be sure to handle them gently to avoid damaging the kernels or bruising the husk. It is best to harvest corn in the morning, when the dew is still on the plants, as this helps to preserve the moisture and flavor of the kernels. Once you have harvested the ears, you can remove the husk and silk, and enjoy the delicious and nutritious kernels inside. Whether you eat it on the cob, in a salad, or as a side dish, fresh corn is a delicious and rewarding treat that is perfect for summer meals and snacks.
Can you store ears of corn for later use, and if so, how?
Yes, you can store ears of corn for later use, provided you follow the right procedures. The best way to store ears of corn is to keep them cool and moist, as this helps to preserve the flavor and texture of the kernels. You can store ears of corn in the refrigerator, either with or without the husk, for up to a week. Simply place the ears in a plastic bag or wrap them in a damp paper towel, and keep them in the crisper drawer. You can also freeze ears of corn, either on or off the cob, for up to 6 months.
To freeze ears of corn, you will need to blanch them first to inactivate the enzymes that can cause the kernels to become tough or bitter. Simply drop the ears into a pot of boiling water for 5-10 minutes, then remove them and plunge them into an ice bath to stop the cooking process. Once the ears have cooled, you can remove the husk and silk, and cut the kernels off the cob. Place the kernels in airtight containers or freezer bags, and store them in the freezer at 0°F (-18°C) or below. Frozen corn is perfect for soups, stews, and casseroles, and can be just as delicious as fresh corn when cooked properly.
