Which one of the following organic substances is most abundantly found in nature ?

The correct answer is (b), cellulose. Cellulose is the most abundant organic substance on Earth, making up about 35% of all plant matter. It is a long, chain-like molecule made up of glucose units. Cellulose is the main structural component of plant cell walls, and it is also found in wood, cotton, and paper. Cellulose is an important source of fiber in the human diet, and it is also used in a variety of industrial applications, such as the manufacture of paper, textiles, and biofuels.

Glucose (a) is a simple sugar that is found in the blood and is used by the body for energy. Fructose (c) is another simple sugar that is found in fruits and honey. Sucrose (d) is a disaccharide, which is a sugar that is made up of two monosaccharides, glucose and fructose. Sucrose is found in table sugar, honey, and many fruits.

Here are some additional details about each of the options:

• Glucose is a simple sugar that is found in the blood and is used by the body for energy. It is also the main building block of starch and cellulose. Glucose is a white, crystalline solid that is soluble in water. It has a sweet taste and is used as a sweetener in many foods.
• Fructose is a simple sugar that is found in fruits and honey. It is also known as fruit sugar. Fructose is a white, crystalline solid that is soluble in water. It has a sweet taste and is used as a sweetener in many foods.
• Sucrose is a disaccharide, which is a sugar that is made up of two monosaccharides, glucose and fructose. Sucrose is found in table sugar, honey, and many fruits. It is a white, crystalline solid that is soluble in water. It has a sweet taste and is used as a sweetener in many foods.
• Cellulose is a polysaccharide, which is a sugar that is made up of many monosaccharides. Cellulose is the main structural component of plant cell walls. It is a long, chain-like molecule made up of glucose units. Cellulose is an important source of fiber in the human diet, and it is also used in a variety of industrial applications, such as the manufacture of paper, textiles, and biofuels.
