(1) Cotton Cotton is a soft fibre that grows around the seeds of the cotton plant .cotton fibre grows in the seed pod or boll of the cotton plant . Fibres that are obtained from plants or animals are called natural fibres.Examples are cotton, jute, wool, and silk.Fibres that are made by man from chemical substances are called synthetic fibres.Examples are nylon, rayon, polyester, and acrylic. The basic structure of a cotton plant includes the main stem, which is made up of a series of nodes and internodes, and two types of branches, vegetative and fruiting branches (NCC, 1996). 5. )After, the cotton fiber is gathered from the plant, it can be spun into cotton thread. They're usually separate, but they can fuse into a cup, tube or ring in some plants. The abundant plant life in forests takes in carbon dioxide and stores the carbon as a source of energy. D. Contributes to global warming. Pteridophytes occupy the intermediate position between Bryophytes and Phanerogams (seed plants). It is these characteristics, it can be made into sacks and hemp rope, etc. Jupiter: It is the largest planet of the solar system as a diameter of 142,980 kilometers.

Meristematic Tissue On the Basis of Function Protoderm. 2. Stanley (1935) isolated pure crystal of Tobacco Mosaic Viruses (TMV) and concluded that viruses are made of nucleoproteins. or most of their body […] Stamens and pollen grains are spongy and water-proof. For decades, clothing manufacturers have used blended cotton and polyester so they can enjoy the benefits of both. Cotton fiber is a cellulosic fiber. The two main characteristics scientists use when classifying plants are reproduction and flowering capability. highly crystalline, oriented and fibrillar (Hsieh, 2007). Cotton is the fine seed hair of plants of the Mallow family; the fibre serves probably to accumulate moisture for … Cotton doesn't stain easily. Each fiber is a single elongated cell that is flat twisted and ribbon-like with a wide inner hollow (lumen). It has high amounts of lime, iron, magnesium and generally low quantities of phosphorus, nitrogen and organic matter. They either remain fully submerged in the water like Hydrilla, Valisineria, etc. Cotton is a natural, soft fiber that grows with the seeds of the cotton plant. 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. The top producers are China, India, United States, Pakistan and Brazil. During active growth, the ideal air temperature is 70 to 100°F (21-37°C). Pollen grains are sticky so that they can stick easily to insect’s body parts. The Wide Range of Byproducts Produced by the Cotton Plant. 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. It has two moons. Cotton has been cultivated and used to make fabrics for at least 7,000 years. A plant kingdom is further classified into subgroups. Abelmoschus – A large genus of herbs, shrubs and trees. They are also very light. These divide preclinically or radially and give rise to secondary permanent tissues. The term Pteridophyte is derived from two words ‘Pteron’ meaning feather and ‘phyton’ meaning plant. 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. Large and coloured petals to attract insects. Gossypium – Cultivated for cotton. Cotton is the collective name given to four species of plants in the genus Gossypium, Gossypium hirsutum, Gossypium barbadense, Gossypium arboreum and Gossypium herbaceum which are perennial shrubs in the family Malvaceae grown for the fluffy fiber which protects the seeds of the plant.G.
