Native to various parts of Central America , the corn flora ( Zea mays ) has been grown and breed by human race for century , confounding botanists as to their precise native part or genic individuality . Overall , there are four species of wild corn whiskey . Corn raise quickly as an annual , completing its intact living cycle in one spring up season .

Size

Corn plants grow rapidly when supply a moist , fat soil with ample heat and sun . Depending on the specific transmitted limit of any assortment of corn , mature plants reach a summit anywhere from four to 12 feet in height , and a spread of leaves from two to four foot across . The stem of the corn whiskey plant is about one inch in diam and gradually tapers to a smaller diam at the top of the plant , where the flower tassel pass .

Root System

consort to I Kisan , an online resource on crops by the government of India , a corn flora farm three types of root in its life . When the seed stock , the germinal beginning are the first origin that branch off the first taproot ( the radicle ) that emerges from the seed . Once a stem forms on the maize plant , the downcast nodes on the theme educate roots that grow downward to the soil surface , work " property " or adventitious roots that help steady the tall , fast - growing stems and leave in the wind and rainwater of summertime . From the nodes on the prow that is in contact with or just below the soil surface , fibrous , horizontal root extend outwards to facilitate the uptake of nutrients and piss . In favorable conditions , these fibrous roots extend up to two human foot down and outwards from the corn plant ’s base .

Plant Tissue Composition

Since corn is a monocot , it develop a structure of cells that have parallel mineral vein , particularly in the foliage . The unshakable , rigid tissues of the central shank are fertile in sclerenchyma cells that provide the strength and overall structure to the works . Within the leafage these cells also subsist , helping maintain the longsighted , narrow leaf blades horizontally to catch the rays of the sun . Vascular tissues , xylem and phloem , are found in the root , stems and leaves . Xylem tissue paper flow water , hormones and liquids upward in the works while downward crusade of the same occurs in phloem cells . Cells that actively lead photosynthesis are in the first place oriented in the upper layer of farewell while leaf undersides are full of line space and stoma , which open and snug for gas substitution and to release or retain water vapor .

Flowering Structures

Corn plants bear both manly and distaff " flowers . " At the top of the corn plant is the male - gendered tassel ( technically a panicle inflorescence ) that releases pollen grain to the current of air . Further down the works ’s stem , at the base of a leaf in the mediate acme form one or on occasion two female capitulum ( a spikelet efflorescence ) . The silky but sticky hair that protrude from the ears are attach to an ovary on the unfledged corn cobnut ( a rachis ) within the ear . As pollen falls upon each hair the ovary is pollinate , and fertilized soon thereafter .

Fruit

The ovary that line the Indian corn cob swell and mature the individual embryos inside each . Collectively , all the ovaries on the corn cob crestless wave to create numerous rows of flattened seeded player . Eventually the seeds reach a maximal size and dry at the same fourth dimension the rest of the corn plant degrades and begins to dry and die . As a texture , the fruit of the Indian corn is botanically called a caryopsis , defined as a ironic fruit with a ejaculate coat that is blend to the ovary paries .
