The key difference between brachiopod and bivalve is that brachiopod belongs to the phylum Brachiopoda while bivalve belongs to the phylum Mollusca. Brachiopod and bivalve are two different organisms that have a shell with two valves. However, the two valves of the brachiopod shell are unequal in size while the two valves of the bivalve […]

Difference Between Epicotyl and Plumule
The key difference between epicotyl and plumuleĀ is that epicotyl is the part of the embryonic axis which lies above the point of attachment of cotyledons while plumule is the tip of the epicotyl which gives rise to the shoot of the new plant. The seed is the ripened ovule which contains the embryo. Here, the […]
Difference Between Alcoholic KOH and Aqueous KOH
The key difference between alcoholic KOH and aqueous KOH is that alcoholic KOH forms C2H5O— ions while aqueous KOH forms OH– ions upon dissociation. KOH is potassium hydroxide. It is an inorganic compound we categorize as an ionic compound. Therefore, it can dissociate into two ions as K+ ion and OH– ion. However, if KOH […]
Difference Between Psi and Bar
The key difference between psi and bar is that psi measures pressure as a one-pound force applied on an area of one square inch whereas bar measures pressure as a force applied perpendicularly on a unit area of a surface. Pressure, in general, is the force perpendicularly applied on a unit area of a surface. […]
Difference Between Indicator Electrode and Reference Electrode
The key difference between indicator electrode and reference electrode is that indicator electrode responds to changes in the activity of the analyte, whereas reference electrode does not respond to changes, and its response is stable. Indicator electrode and reference electrode are two important components in potentiometric titrations. These are essential to make a potential measurement. […]
Difference Between Potentiometric and Conductometric Titrations
The key difference between potentiometric and conductometric titrations is that potentiometric titrations measure the potential across the analyte, whereas conductometric titrations measure the electrolytic conductivity of the analyte. A titration is an analytical technique in which we can determine the concentration of an analyte. Here, we need a titrant which acts as the standard solution […]
Difference Between Endosperm and Perisperm
The key difference between endosperm and perisperm is that endosperm is a nutritive tissue of the seed that is triploid in nature, while perisperm is another nutritive tissue of the seed that is diploid in nature. Seed plants have two major categories as angiosperms and gymnosperms. Angiosperms bear closed seeds while gymnosperms bear naked seeds. […]
Difference Between Guard Cells and Subsidiary Cells
The key difference between guard cells and subsidiary cells in plants is that guard cells are the specialized parenchyma cells that enclose stomata present in the epidermis of leaves, stems, etc. while subsidiary cells are the surrounding supportive cells of guard cells. Stomata are the pores located in plant epidermis that facilitate the gaseous exchange. […]
Difference Between Bar and Barg
The key difference between bar and barg is that bar indicates absolute pressure, whereas barg indicates gauge pressure. Pressure is the force applied perpendicularly on a unit area of a surface. There are three types of pressure as absolute pressure, gauge pressure and differential pressure. Absolute pressure is the measurement we take against a perfect […]
Difference Between TGF Alpha and Beta
The key difference between TGF alpha and beta is that TGF alpha is an epidermal growth factor that induces epithelial development while TGF beta is a cytokine-based growth factor that participates in numerous signalling pathways in a cell. TGF alpha and beta are two classes of polypeptide growth factors which take part in many functions […]
