Sugar yielding part of Beta vulgaris is

  1. Leaf

  2. Shoot

  3. Root

  4. All the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sugar beetroots are processed into white sugar, pulp and molasses for food, feed or industrial applications. A typical sugar beetroot consists of 75.9% water, 2.6% non-sugars, 18.0% sugar and 5.5% pulp. In the sugar fraction, 83.1% is recovered as crystalline sucrose, 12.5% is recovered as molasses.

So the correct option is C.

Name the main constituent of the food, in the absence of that one cannot live

  1. Carbohydrates

  2. Mineral salts

  3. Proteins

  4. Vitamins
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbohydrate is the major source of energy without which one cannot live. It is because carbohydrate is broken down to form instant energy in the form of glucose which can be converted into ATP and thus used for the regular functioning of the cell. Other forms of energy like proteins, vitamins, and minerals are the extra components that are not directly involved in the formation of energy.

So, the correct option is 'carbohydrates'

Various types of crystals of calcium carbonate or oxalate are reported in certain families which can also be regarded as aid to taxonomy. Crystals of gypsum are present either singly or in clusters in

  1. Tomarix dioica

  2. Ficus benghalensis

  3. Momordica charantia

  4. Nymphaea sp.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Crystals of calcium oxalate, starch grains, stone cells with lignified walls, brown tannin cells, and crystals of gypsum are present in the cells of Ficus benghalensis, they belong to family Moraceae. The presence of different crystals is the characteristic feature that distinguishes families from each other.

So, the correct option is 'Ficus benghalensis'.

Which of the following categories of macromolecules includes representatives that  frequently serve as energy storage molecules?

  1. Proteins

  2. Lipids

  3. Carbohydrates

  4. Both lipids and carbohydrates
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Energy storage molecules are those molecules which store energy in the form of covalent chemical bonds. Some molecules like glycogen (carbohydrate) and triglycerides (lipids) are synthesized by the cells and they are stored for the later release of energy. So, the correct answer is "both lipids and carbohydrates".

A Correct answer
Explanation

Ceramic solids are composed of inorganic compounds, usually oxides of chemical elements. They are chemically inert, and often are capable of withstanding chemical erosion that occurs in an acidic or caustic environment.

Which biomolecule is made up of long chain of amino acids?

  1. Lipids

  2. Proteins

  3. Carbohydrates

  4. Nucleic acids
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Proteins are the polymers of amino acids held together by peptide bonds. Carbohydrates are polyhydroxy aldehyde or ketones or their derivatives. Nucleic acids are polymers of nucleotides held together by phosphodiester bonds. Lipids are the chemically diverse group and mostly have long hydrocarbon chain. Thus, the correct answer is B.

Amino acids form the monomeric units of 

  1. Amylase

  2. Glycogen

  3. Phospholipid

  4. Polysaccharide

  5. Ribonucleic acid
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Amylase is peptide hormone and consists of amino acids as monomer subunit. Glycogen is homopolysaccharide of D-glucose while lipids having attached phosphate groups are called as phospholipids. Polysaccharides are polymers of simple sugars (single polyhydroxy aldehyde or ketone unit). Ribonucleic acid is a polymer of ribonucleotide monomers. Thus, the correct answer is A.
