What is the structure of maize?
Endosperm: Maize grain consists of two unequal portions divided by a layer called epithelium. The bigger portion, the endosperm which is yellowish or whitish is the food storage tissue of the grain and is rich in starch. But its outermost layer contains only protein and is called aleurone layer.
What is maize leaf?
The maize leaf is composed of a stem-gripping proximal sheath and a long distal blade joined together by an auricle and membranous ligule. This hinge-like region allows the blade and supporting midrib to bend away from the stem, thereby affecting plant architecture and yield.
What is the root system of maize plant?
Root: Normally maize plants have three types of roots, (i) seminal roots – which develop from radical and persist for long period; (ii) adventitious roots, fibrous roots developing from the lower nodes of stem below ground level which are the effective and active roots of plant; and (iii) brace or prop roots, produced.
What is the difference between corn and maize?

How is maize grown?
Maize is sown in rows, 60-75 cm apart, whereas the plants in the row are spaced at 20 to 25 cm. A population of 60-75 thousand plants per hectare at harvest are required for obtaining the optimum yield. Sowing in rows is generally done with drill or by dropping the seed behind the plough.
What is the structure of maize seed?

How is a maize plant propagated?
Maize is an out-crossing species normally propagated from seed . Vegetative propaga- tion, however, could be a useful tool in maize research. Mating designs developed for multiflowered plants, e.g., Design II of COMSTOCK and ROBINSON (1952), could be carried out with clonal material .
What is the first step in plant breeding?
1. Collection of variability- The first step of plant breeding is to collect all the genetic variability present in wild relatives of cultivated varieties of plants. The collection of diverse alleles of a gene in a crop is called germplasm collection. From this collection, breeders can select desired characters.
What is the shape of leaf blade of maize plant?
The leaf blades are linear to linear-lanceolate in shape, while their margins are entire (without conspicuous teeth) and often ciliate near the bases of the leaf blades. In addition, the leaf blades may have narrow longitudinal wrinkles, and they are sometimes vertically wavy (up and down).

Is maize a fruit?
Whole corn, like you eat on the cob, is considered a vegetable. The corn kernel itself (where popcorn comes from) is considered a grain.

Scientists believe people living in central Mexico developed corn at least 7000 years ago. It was started from a wild grass called teosinte. Teosinte looked very different from our corn today. The kernels were small and were not placed close together like kernels on the husked ear of modern corn.
