Three important parts of the corn kernel are the pericarp (seed coat), endosperm, and embryo.
What are the parts of a kernel of corn?
corn kernel consists of four major components: hull or pericarp, endosperm, germ and tip cap as shown in Figure 3. The endosperm is primarily starch, the corn’s energy storage, and protein for germination. The pericarp or hull is made of cellulosic material and protects the kernel from microorganisms and insects.
What are the three main parts of a grain kernel?
All whole grain kernels contain three parts: the bran, germ, and endosperm. Each section houses health-promoting nutrients. The bran is the fiber-rich outer layer that supplies B vitamins, iron, copper, zinc, magnesium, antioxidants, and phytochemicals.
What are the four parts of corn?
The kernel is made up of four major components – starch, fiber, protein and oil – that can be processed in different ways to be used in all kinds of products. In fact, a typical grocery store contains 4,000 items that list corn ingredients on the label.
What is the inside of a kernel of corn called?
The germ
The germ is the only living part of the corn kernel. The germ contains the essential genetic information, enzymes, vitamins and minerals for the kernel to grow into a corn plant. About 25 percent of the germ is corn oil-the most valuable part of the kernel, which is high in polyunsaturated fats and has a mild taste.
Where is the kernel in corn?
The corn kernel is the fruit or caryopsis borne in the female inflorescence of the plant, which contains the embryo and storage tissues designed to create upon germination the new seedling and generation plant.
What are the things on corn called?
At the top of a mature corn plant is the tassel, the male part of the plant. Along the stalk are the leaves and the ears of corn, wrapped closely in husks. Hundreds of filaments, called silk, protrude from the top of each ear.
What are the 3 major types of grains?

Which is not one of the three main parts of a grain kernel?
A grain contains three parts: bran, germ and endosperm. The bran is the outer layer and is rich in fiber. The germ is the inner layer and is rich in nutrients. The endosperm is the bulk of the kernel and contains some of the vitamins and minerals.
What parts of the kernel is the whole grain?
Whole grains contain all three parts of the kernel. Refining normally removes the bran and the germ, leaving only the endosperm. Without the bran and germ, about 25% of a grain’s protein is lost, and are greatly reduced in at least seventeen key nutrients.
Is a kernel a seed?
1. The essential part of a seed; all that is within the seed walls; the edible substance contained in the shell of a nut; hence, anything included in a shell, husk, or integument; as, the kernel of a nut.
What are individual pieces of corn called?
Kernels. The kernels are all attached to the hard core and are essentially the seeds (also called the fruits) of the plant. They have one main function and that is to make another corn plant! However, as you already know, corn kernels are the parts that we use in food and to create corn-based food products.
What is the hairy part of corn called?
The long shiny fibers at the top of an ear of corn are called corn silk.
What part of a corn do we eat?
“Corn is a seed derived from the flower/ovary of the corn plant,” he says, “so is technically a fruit.” More specifically, corn is a caryopsis, which is a type of fruit in which the seed coat is tightly fused with the pericarp (that’s the fleshy bit, like the part of a peach that you eat).
What is top of corn called?
Every corn plant has both male and female parts. The male part, which is known as the tassel, emerges from the top of the plant after all the leaves have emerged. The tassel usually consists of several branches, along which many small male flowers are situated.
Why is it called a corn kernel?
The old spelling of corn was Korn, from the Germanic; Kernel is a diminutive form, to mean a small grain. Niblets is a trademarked name that Green Giant uses to describe the fresh corn kernels it sells in North America and in the UK.
Does each kernel of corn have a silk?
Each kernel on the ear has a silk. A single ear is estimated to have anywhere between 750 to 1,000 kernels. Not every kernel is successfully pollinated, so most ears (in a good year) will produce only 400 to 600 kernels. As silks emerge, anthers (which are located on the tassels) should be visible.
What do you mean by kernels?
Definition of kernel
1 : the inner softer part of a seed, fruit stone, or nut … as brown in hue as hazelnuts, and sweeter than the kernels.— William Shakespeare. 2 : a whole seed of a cereal a kernel of corn. 3 : a central or essential part : germ like many stereotypes …
Is a corn kernel a fruit?
Corn is a fruit, a grain and a vegetable. Botanically speaking, corn is a fruit. It is produced from the flower or the ovary of the corn plant. Specifically, corn is classified as a caryopsis, a one-seeded fruit where the seed pod and the flesh are tightly joined together.
Is corn a whole grain?
Corn is a whole grain if the bran, germ, and endosperm are all left intact, just like whole wheat. If the corn is milled or degermed to remove the bran and germ, then it is a refined grain.
Is corn a vegetable?
Fresh corn is considered a starchy vegetable. Its nutrient content differs from dry corn, and it is eaten in different ways — often on the cob, as a side dish, or mixed with other vegetables.
