The key difference between open cup and closed cup flash point is that open cup method gives usually higher values for the flash point than closed cup method. Flash point is the lowest temperature at which the flammable vapour of a volatile liquid ignites when we provide it with an ignition source. There are two […]
Difference Between Microspore and Pollen Grain
The key difference between microspore and pollen grain is that microspore is the small spore that develops into the male gametophyte in plants while pollen grain is the small grain that contains the male gametophyte. Plant reproduction takes place both sexually and asexually, showing the alternation of generation. There are two generations known as sporophytic […]
Difference Between RTV and Silicone
The key difference between RTV and silicone is that RTV is a general term for room temperature vulcanizing silicone, whereas silicone is a polymer material having repeating units of siloxane. RTV stands for room temperature vulcanizing. More precisely, RTV is a general term we use to refer to “RTV silicone” which is a type of […]
Difference Between Epicotyl and Plumule
The key difference between epicotyl and plumule 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. […]
