Assisting in seed spreading is the main botanical purpose of cotton fiber. It’s earliest use dates back to at least 5800 BC. Cotton is a natural fabric harvested from crops, whereas polyester is a man-made polymer derived from natural chemicals. Cotton thread is compatible with fabric made from yarn of plant origin, such as cotton and linen, and for rayon (made from a plant substance), because it has similar shrinkage characteristics. It orbits the sun in 12 years. All plant cells share the same key components and characteristics, even though like humans, plants have many different kinds of cells specialized at carrying out different functions. It is black in colour since it is formed from weathered lava rocks. These divide preclinically or radially and give rise to secondary permanent tissues. 5. Cotton is made from the natural fibers of cotton plants, which are from the genus Gossypium.. Cotton is primarily composed of cellulose, an insoluble organic compound crucial to plant structure, and is a soft and fluffy material. The abundant plant life in forests takes in carbon dioxide and stores the carbon as a source of energy. Iwanowski (1892) first discovered virus in an infected tobacco plant. The pistil is the female reproductive organ. Cotton has been cultivated and used to make fabrics for at least 7,000 years. These soils have a good ability to transport water by capillary action from deep layers but the rate is slow, so plant water requirements are not met through capillary water. Cotton is a soft fiber that grows around the seeds of the cotton plant. E.g. Then the gin's saws and teeth separate the cotton fiber from the seeds, sending them in different directions.

Creates pollution with the use of DDT, which is a fertilizer that impacts the health of many organisms in the area. There, machines feed the cotton into a cotton gin, which pulls the cotton fibers apart to remove unwanted debris such as dirt, twigs, burs, leaves and other plant material. Pteridophytes occupy the intermediate position between Bryophytes and Phanerogams (seed plants). Each fiber is a single elongated cell that is flat twisted and ribbon-like with a wide inner hollow (lumen). It is well-known for its system of three rings, it has also 47 moons. each fibre is a single elongated cell that is flat twisted and ribbon like with a wide inner hollow (lumen). It has worldwide popularity for its variety of use. The blend has a number of characteristics that make it ideal for use in modern clothing. 5. 1) cotton is both a food and fiber crop 2)cotton is non ellergenic 3) cotton keeps cool in summer and hot in winter becoz its good conductor of heat TheRuhanikaDhawan TheRuhanikaDhawan characteristics properties of cotton Cotton fiber is the most used fibers for producing various types of fabric through all over the world.
