The key difference between root nodules and mycorrhizae is that root nodules are a type of symbiotic association between nitrogen-fixing bacteria and plant roots, while mycorrhizae are a type of symbiotic association between higher plant roots and fungi. There are several types of symbiotic interactions between different organisms. Among them, mutualism, commensalism and parasitism are […]

Difference Between Ligand and Chelate
The key difference between ligand and chelate is that ligands are the chemical species that donate or share their electrons with a central atom through coordination bonds, whereas chelates are compounds containing a central atom bonded with surrounding ligands. We can define a ligand as an atom, ion, or molecule that can donate or share two of its electrons […]
Difference Between Volumetric Pipette and Graduated Pipette
The key difference between volumetric pipette and graduated pipette is that we can measure only a certain volume from a volumetric pipette, whereas we can measure a range of volumes from a graduated pipette. A pipette is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often […]
Difference Between Molecular and Antigen Test
The key difference between molecular and antigen test is that molecular test detects specific parts of the genetic material of a pathogen while antigen test detects specific protein markers called antigens present on the surface of the pathogen. Molecular test and antigen test are two types of diagnostic tests used to detect active infections like […]
Difference Between Law of Constant Composition and Law of Multiple Proportions
The key difference between law of constant composition and law of multiple proportions is that according to the law of constant composition, the same proportion of samples always consists of the same proportion of elements by mass, whereas according to the law of multiple proportions, if two elements bind with each other forming more than […]
Difference Between Crucible and Evaporating Dish
The key difference between crucible and evaporating dish is that crucible is a container used for the melting of metals or subjecting of substances to high temperatures whereas evaporating dish is a container used for evaporation of solutions and supernatant liquids. Crucible and evaporating dish are important laboratory glassware that often comes into contact with […]
Difference Between Peptic and Oxyntic Cells
The key difference between peptic and oxyntic cells is that peptic cells secrete pepsinogen and gastric lipase while oxyntic cells secrete hydrochloric acid and intrinsic factor. Gastric glands are mostly exocrine glands that secrete various enzymes, mucus, hydrochloric acid and hormones. They are present beneath the gastric pits within the gastric mucosa. Chief cells or peptic cells and parietal cells or […]
Difference Between Perfectly Elastic and Perfectly Inelastic Collision
The key difference between perfectly elastic and perfectly inelastic collision is that in perfectly elastic collisions, the total kinetic energy of the objects remains the same, whereas, in perfectly inelastic collisions, the total kinetic energy of the objects does not remain the same. A perfectly elastic collision is the opposite of a perfectly inelastic collision. […]
Difference Between Meissner’s and Auerbach’s Plexus
The key difference between Meissner’s and Auerbach’s plexus is that Meissner’s plexus is in the submucosal tissue of the intestine, while Auerbach’s plexus is between the circular muscle layer and longitudinal muscle layer in the lower esophagus, stomach, and intestines. Digestive nerve plexus or enteric nerve plexus are intricate layers of nervous tissue. They are […]
Difference Between Potassium Chromate and Potassium Dichromate
The key difference between potassium chromate and potassium dichromate is that potassium chromate appears in yellow colour, whereas potassium dichromate appears in orange colour. Potassium chromate and potassium dichromate are closely related inorganic compounds having similar chemical structures. The dichromate ion in potassium dichromate is made from the combination of two chromate ions. CONTENTS 1. Overview […]
