A closer look at the composition of a corn kernel. The pericarp is the outer covering that protects the kernel and preserves the nutrient value inside. It resists water and water vapor — and is undesirable to insects and microorganisms. The germ is the only living part of the corn kernel. One ear of corn roughly has 16 rows and about 800 kernels in total. Each kernel consists of endosperm, germ, pericarp, and a tip cap. The tip cap is a relatively unknown part of a kernel and is basically attached to the point of the kernel. It is attached directly to the cob (the hard inside) and helps transfer water and nutrients.

Corn Roots Corn plants are unusual in that they have two distinct sets of roots: regular roots, called seminal roots; and nodal roots, which are above the seminal roots and develop from the plant nodes. The seminal root system includes the plant's radicle (the first root emerging from the seed). A typical corn plant grown by a farmer in the central United States will have a stalk that is 7 to 10 feet tall and has 16 to 22 leaves. The lower part of each leaf wraps around the stalk and is attached to the stalk at a juncture called a node. Typically the lowest four nodes are below ground. Roots develop from each of these nodes. Corn kernels are the fruits of corn (called maize in many countries). Maize is a grain, and the kernels are used in cooking as a vegetable or a source of starch. The kernel comprise endosperm, germ, pericarp, and tip cap. One ear of corn contains roughly 800 kernels in 16 rows. Updated: 09/29/2022 Corn Anatomy Corn is the most abundantly produced agricultural grain, followed by wheat and rice. Referred by the scientific name Zea mays, corn is a highly domesticated.

Definition White inside part of the kernel composed primarily of starch. Acts as nourishment for the dormant kernel as well as for the newly germinated plant when the kernel starts to grow. Location Term Hard (vitreous) Endosperm Definition . 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. This chapter reviews relevant information on the physical properties of the corn kernel and the constitution and functionality of its anatomical parts and is mainly focused on to establish a solid foundation of the current state of knowledge of the anatomy and architecture of the corn kernel. Corn seed germination diagram with labeled structures; Procedures for Instruction. Corn kernels are monocots, and beans are dicots. Inside a corn kernel (seed), there is a cotyledon near the bottom, pointy part of the kernel, where the new plant begins to grow. It is surrounded by the endosperm, which is starchy food for the baby plant.

Ear: the structure that contains the kernels that are forming after fertilization. The female part of the corn plant. Kernel: it is the corn seed with one main function; to make another corn plant. Node: a place on the stem where growth occurs. Leaves, roots, ears, and tassels form from nodes. Stalk: the main body (stem) of the corn plant. Figure \(\PageIndex{7}\): Diagram of a corn kernel, an example of a "complex" monocot. The single cotyledon is called the scutellum. The outer layer is the pericarp (fruit wall) fused with the seed coat. The endosperm fills much of the seed and stores starch. It actually consists of a thin outer layer (aleurone) and a thick inner layer (starchy.

Composition of Corn Plant. The structure of the corn kernel consists of six physical parts, which can be identified as the tip cap, the hull (source of fiber [ 34, 35 ]), the horny gluten, the horny starch, the white starch, the germ [ 36 ]. Figure 2 shows parts of corn plant. The structure of the corn kernel and the composition of its different parts by Hopkins, Cyril G. (Cyril George), 1866-1919; East, Edward M.
