In the osazone test, reducing sugars like glucose or fructose react with phenylhydrazine to form crystalline derivatives called osazones. While starch itself is a polysaccharide and does not directly participate in this reaction, when starch is hydrolyzed into its constituent glucose units, these reducing sugars can then react with phenylhydrazine to form osazones. Sucrose, being a non-reducing sugar, does not form osazones unless it is first hydrolyzed into glucose and fructose. Thus, it is the monosaccharides released from starch and sucrose that contribute to the formation of the crystalline osazones.
Glucose, sucrose, and starch are all carbohydrates made up of sugar molecules. Glucose is a simple sugar that is a building block for both sucrose (a disaccharide made of glucose and fructose) and starch (a polysaccharide made of multiple glucose units). They are all sources of energy for living organisms.
The nutrient made of starch, sucrose, and fiber is carbohydrates. Carbohydrates are a major source of energy for the body and can be categorized into simple carbohydrates (like sucrose) and complex carbohydrates (like starch and fiber). While starch and sucrose provide readily available energy, fiber plays a crucial role in digestive health and regulation.
Starch is not a simple sugar. Rest are.
they form sucrose.
In a flowering plant, the glucose is formed during photosynthesis is stored in the form of starch(insoluble)...but when it is needed, it is converted to sucrose(soluble) which flows through the phloem and is utilized, while rest is again converted to starch and storedhence, it is transported in the form of sucrose
Carbohydrates are in starch, glucose, and sucrose. The "ose" suffix is mostly about carbohydrates.
From smallest to largest: NaCl, Water, Glucose, Sucrose, Starch. They are ordered based on their molecular weight and size.

glucose
starch is polysaccharide.glucose and fructose are monosaccharides.sucrose is a disaccharide.
Ribose is the smallest molecule among sucrose, lactose, ribose, and starch. Ribose is a simple sugar with only 5 carbon atoms, while sucrose, lactose, and starch are larger molecules composed of multiple sugar units.
they form sucrose.
Starch is not a simple sugar. Rest are.
starch is formed by fermentation.
In a flowering plant, the glucose is formed during photosynthesis is stored in the form of starch(insoluble)...but when it is needed, it is converted to sucrose(soluble) which flows through the phloem and is utilized, while rest is again converted to starch and storedhence, it is transported in the form of sucrose
sucrose is the storage form of glucose in leaves... and it may also starch.
