  • As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids
  • The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium All of the remaining elements in a human body are called "trace elements". The trace elements are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine and selenium. Hence, silicon is not a major nutrient for the body.

A green leaf is partially covered and placed in the light for several days. If it is then boiled and tested for starch with iodine, what will be the result?

  1. Starch will be found only in the shaded part of the leaf

  2. Starch will be found in the entire leaf

  3. Starch will be found only in the part of the leaf exposed to light

  4. Starch not be found in the leaf at all
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The leaf on the right shows a positive test for starch in the areas which contained chlorophyll, and a negative test for starch in the areas which lack chlorophyll. This is evidence that chlorophyll is required for photosynthesis. A plant can be 'de-starched' by leaving it in the dark for a few hours. So, the correct option is "C" (Starch will be found only in the part of the leaf exposed to light).

Iodine gives blue-black colour with

  1. Protein

  2. Oil

  3. Starch

  4. Sucrose
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The iodine test is used for the determination of the presence of starch in a sample. Molecular iodine is not soluble in water and hence potassium iodide is added to it. Together they form polyiodide complex which upon addition of starch turns intense blue-black colour. Starch is a polymer of amylose and amylopectin, of which amylose is responsible for the blue colour of the reaction. In the absence of starch solution remain as light brown colour which is the colour of iodine solution.
