Deep in the plant system, such as in the leaves, flowers, fruits, seeds, stem or roots, plant starch is found and is formed in the organelles of plant cells such as chloroplasts in plants with green leaves that rapidly produce starch; and in amyloplasts commonly found in root crops in which starch reserves are stored over several days or weeks, whose starch storage is mobilized during seed germination, fruit ripening, or tuber sprouting. Starch is the most abundant carbohydrate in plants and is used by plants as a source of carbon and energy. Say no to plagiarism.

First, since it comes from plants consumed by living things, it serves as a source of carbohydrates in a balanced diet. On the other hand, it acts as a renewable element in the industrial world, making it useful to both humans and the commercial world. As for its usefulness in the industrial world, its versatility ranges from being a thickening agent in processed foods, as it gelatinizes leading to the formation of pastes when heated in water; up to the non-food category as it can be produced as paper or cardboard in some companies, packaging materials in some other factories and even biodegradable plastic. Over the years, starch has gradually been used in many industrial uses including as a renewable energy source in the economy. The development of technologies and methods has increased the use of waste especially in plants which makes starchy biomass a consequential proxy element in various uses in different inventions due to its usefulness, versatility, accessibility and low-cost quality. Cereals contain 40-90% starch, roots 30-70%, tubers or potatoes up to 65-85%, legumes 25-50% and some unripe fruits such as bananas or mangoes which contain approximately 70% starch. dry weight. Starches are useful in today's production of containers and other biodegradable materials that emerge along with today's developments due to their accessibility and economical quality compared to other polymers. Starches evidently attract a lot of attention from packaging industries for their natural source of low-cost polymer, useful in the production of bioplastics. They are digestible by microorganisms, making its biodegradability excellent and environmentally friendly. Furthermore, starches produce hydrophilic bioplastics due to their hydroxyl end groups. Potatoes, a well-known root crop, are known to have originated in tropical areas, particularly in the Andes of South America, where it is known to be the number one cultivated crop in the area. However, potatoes have a highly adaptive nature, which makes them capable of growing anywhere in the world and in all climates, ranking second among the most cultivated crops in the largest number of countries in the world. A potato contains approximately 18% starch, 1% cellulose and 81% water and contains dissolved organic compounds such as proteins and carbohydrates, therefore potato harvesting has a great impact as it plays a role in maintaining a low level of damage to tubers. However, along the lands of tropical and subtropical countries, species of Musa paradisiaca or simply bananas abound, belonging to the Musaceae family which abound in these areas where they are widely cultivated. Bananas, especially the unripe green banana, contain starch as a major component as they undergo numerous stages as they ripen. These plants are considered to be of great industrial importance due to their high starch content.,.
