Practical Medicinal Plant - Starch

Explanation
The correct answer is C6H10O5. This is the general formula for starch, which is a complex carbohydrate composed of multiple glucose molecules bonded together. The formula indicates that starch consists of six carbon atoms, ten hydrogen atoms, and five oxygen atoms. Starch is an important energy storage molecule in plants and is also used as a thickening agent in food products.

Explanation
The correct answer is "low" because leaves and stems primarily function as storage organs for carbohydrates in the form of starch. Starch is a complex carbohydrate that serves as an energy reserve in plants. Since leaves and stems are not major sites of photosynthesis, they do not produce a significant amount of glucose, which is converted into starch. Therefore, the amount of starch in leaves and stems is generally low compared to other plant parts like roots or seeds.

Note That : Ethanol is an Organic Solvent ..

Explanation
When we add phenol to starch, it causes the starch to become transparent and invisible. This is because phenol reacts with the starch molecules, breaking down their structure and causing them to lose their ability to reflect light. As a result, the starch becomes transparent and appears invisible to the naked eye.

Explanation
Potato starch granules have a size range of 30 - 100 µ in diameter. Starch granules are microscopic structures found in plants, including potatoes. They serve as a storage form of energy for the plants. The size of the granules can vary depending on the plant species and the specific type of starch. In the case of potato starch, the granules are relatively large, ranging from 30 to 100 µ in diameter. This size range allows for efficient storage and release of energy when the starch is broken down during cooking or digestion.

Explanation
Wheat starch is obtained from the endosperm of Triticum vulgare. The endosperm is the innermost part of the wheat grain and contains the majority of the starch. This starch is commonly used in food processing, as a thickening agent, and in the production of various products such as noodles, bread, and pastries.

Explanation
Striations are absent in maize and rice starch. Striations refer to the presence of parallel lines or grooves on the surface of starch granules. Maize and rice starch granules have a smooth surface without any visible striations, unlike other starches such as potato starch.

Explanation
The correct answer is maize starch because the question is asking about the number of rays in the hilum, which is a characteristic feature of maize starch. Rice starch and potato starch do not have clefts or rays in the hilum.

Explanation
Rice starch is obtained from the endosperm of Oryza sativa, which is the scientific name for rice. The endosperm is the inner part of a seed that provides nourishment to the developing plant embryo. Rice starch is commonly used in various food and industrial applications due to its unique properties, such as its ability to thicken and stabilize food products.

Explanation
Rice starch is the correct answer because it is a type of starch that is typically found in rice grains. Starch granules are small particles that make up starch, and rice starch granules fall within the size range of 2-150 components. Maize starch and wheat starch may also have granules within this size range, but the question specifically asks for the correct answer, which is rice starch.
