Plant

Corn is tall monoecious annual grass sized 3 m (10 ft.) in height is found growing in tropical and subtropical regions around the world. Normally it prefers well drained, well-aerated, deep soils that contain sufficient organic matter and well supplied with other nutrients. Corn has rough fibrous root system that spreads widely and penetrates deeply and single erect stem made up of nodes and internodes, stem is commonly composed of 20 internodes of 18 cm (7.1 in) length. Leaves are alternate, with broad, sword-shaped leaf blades, parallel veins. Upper surface is hairy, lower surface hairless 50–100 cm long by 3–7 cm wide. Corn plant has separate male and female flowers on the same plant. On the branches, only female organs (called ears) develop in the florets while the male part of the flower (the tassel) produces pollen and is at the top of the plant.

Fruit

Even though considered as a vegetable, it is in reality a food grain. The leafy stalk of the plant provides ears that have the grains known as kernels. For each kernel on the cob, there exists a strand of silk. The white and yellow kernels are most widely used, however nowadays corn can be found in blackish, bluish-gray, purple, green, red, white and yellow depending on the varieties. Pericarp and testa are fused to form the fruit wall. Fruit also called kernel or grain and seed.  An ear commonly holds 800 kernels in 16 rows. Apart from its delightful taste, it is found used in numerous food items around the world.

History

Maize is considered to have originated from Mesoamerica, probably in the Mexican highlands from where it spread. Different Archaelogical data and phylogenetic investigation recommended that domestication of maize in Mexico began at least 6,000 years ago (Piperno and Flannery 2001). Maize was spread around the world after the European discovery of the Americas in the fifteenth century. It is now cultivated worldwide. Maize is only known in cultivation and its exact genealogy remains unclear.
