Green mulberry leaves are the sole principle food of silkworm, which supply nutrients required for the normal growth of the silkworm. This sort of feeding on single host plant is

Photosynthesis is the biggest photochemical reaction and biochemical phenomena acting as a master key for the existence of life on this globe. In turn solar energy is the chief driver of this photochemical reaction.

|
Climate is defined as an area's long-term weather patterns. The simplest way to describe climate is to look at average temperature and precipitation over time. Other useful elements for describing climate i

|
Growth is an important factor of living organism defined as a permanent and irreversible change in size or volume of a living structure. Growth is always seen in meristem prese

Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Or The way in which a living organism or bodily part functions.
|
|
Stomatal index is the measurement of the surface density of stomata. This parameter has been found useful in comparing leaves of different mulberry varieties as it plays very important role in photosynthesis and transpiration.
|
|
Kranz means wreath in German (A wreath is an assortment of flowers, leaves, fruits, twigs, cells or various materials that is constructed to resemble a ring). Kranz anatomy refers to an arrangement of bundle sheath cells surrounded by mesophyll
|
|
The –CO-NH- bond (peptide) in polypeptide chain reacts with copper sulphate in an alkaline medium to give a purple colour which can be measured at 540 nm.
|
|
The separation of photosynthetic pigments is based on partition takes place between the static phase adsorbed to the cellulose matter of the paper and mobile phase.
|
|
The separation of photosynthetic pigments is based on solubility of different pigments with specific solvents.
|
|
Water potential is the potential energy unit volume relative to pure water in reference conditions. The measure of the relative tendency of water to move from one area to another, and is commonly represented by the Greek letter Ψ (Psi).
|
|
Water is one of the important constituents of mulberry leaves and it plays an important role in silkworm crop production. Moisture content varies with variety, season, age of the plant and preservation techniques followed. It is usually expressed in terms of per cent age.
|
|
One of the first steps of photosynthesis is the photolysis of water to donate 2 electrons to the reaction center P680
|
|
The –CO-NH- bond (peptide) in polypeptide chain reacts with copper sulphate in an alkaline medium to give a blue colored complex. In addition, tyrosine and tryptophan residues of protein cause reduction of the phosphomolybdate and phosphotungstate components of

|
Several reagents have been employed which assay sugars by using their reducing properties. One such compound is 3, 5- dinitrosalicylic acid (DNA) which in alkaline solution is reduced to 3
|
|
To prepare the silkworm haemocytes.
|
|
When amylase acts on starch 5-dinitrosalicylic acid (DNS) in alkaline solution to give rise to orange coloured complex, which can be measured at 540 nm.
|
|
Succinate dehydrogenase is one of the mitochondrial enzymes, which catalyzes the conversion of succinate to fumerate. In this reaction FAD reduces to FADH2. In vitro, the lemon yellow colored INT
|
|
Glycogen is released from the tissue by heating with strong alkali and precipitated by the addition of ethanol. Sodium sulphate is added as co-precipitant to give a quantitative yield
|
|
The uric acid reduces phosphotungstic acid in the presence of sodium carbonate to blue coloured complex. The concentration of uric acid is directly proportional to intensity of colour, which can be read n is released from the tissue
