Physical and Chemical Properties of Water: Water is the most abundant substance in the living system. Water makes up about 70% or more of the weight of almost all organisms. The life has originated in remote past in the aqueous environment. The properties (both physical and chemical) of water enabled […]
Hydrogen Bonds in Water: The life was originated and started its evolution in water. Without water, life could not have existed on this planet. The properties of water, both physical and chemical, enabled water as the ‘solvent of life’. The water possesses some unusual physical and chemical properties. These ‘unusual […]
P Proteins (Phloem Proteins) are a category of proteins found in the sap of the sieve tubes of the phloem of Angiospermic plants. P-proteins were also as called ‘slime bodies’ of ‘slime’ in the old literature. P proteins are usually found in the phloem of dicot plants. P Protein Characteristics […]
