The key difference between acanthosis and acantholysis is that acanthosis refers to the thickened epidermis while acantholysis is the loss of intercellular connections between keratinocytes. Acanthosis and acantholysis are two skin conditions related to the epidermis. Acanthosis is the thickened epidermis. The increased thickness of the malpighian layer is the cause for acanthosis. Acantholysis is […]
Difference Between Granular and Agranular Endoplasmic Reticulum
The key difference between granular and agranular endoplasmic reticulum is that granular endoplasmic reticulum has ribosomes over the surface while agranular endoplasmic reticulum does not have ribosomes over the surface. Endoplasmic reticulum (ER) is a series of flattened sacs and a network of tubules present in the cytoplasm of eukaryotic cells. ER is an important organelle […]
Difference Between Trophoblast and Inner Cell Mass
The key difference between trophoblast and inner cell mass is that trophoblast is the outer cell layer of the blastocyst that nourishes the embryo and develops into a large part of the placenta while inner cell mass or embryoblast is the innermost cell mass from which the embryo arises. A male sperm unites with an […]
Difference Between Water Potential and Osmotic Potential
The key difference between water potential and osmotic potential is that water potential is the measure of the concentration of free water molecules while the osmotic potential is the measure of the tendency of a solution to withdraw water from pure water through a semi-permeable membrane via osmosis. Water potential and solute potential or osmotic […]
Difference Between Bulk Flow and Diffusion
The key difference between bulk flow and diffusion is that bulk flow is the movement of a fluid or a mass due to a pressure gradient while diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration along the concentration gradient. Bulk flow and diffusion are two methods […]
Difference Between Autogenous Theory and Endosymbiotic Theory
The key difference between autogenous theory and endosymbiotic theory is that autogenous theory states that nucleus and cytoplasm form through evolutionary changes in a single prokaryotic lineage while endosymbiotic theory states that some organelles, especially mitochondria and chloroplasts in eukaryotic cells, were once prokaryotic microbes living in a symbiotic relationship. Eukaryotic cells are notably different […]
Difference Between Spontaneous Generation and Panspermia
The key difference between spontaneous generation and panspermia is that spontaneous generation theory believed that life can arise from nonliving matter while panspermia theory believed that life on earth was transferred from somewhere else in the universe to earth. The origin of life on earth is a very big mystery to human beings. There are […]
Difference Between Pyramid of Biomass and Pyramid of Energy
The key difference between pyramid of biomass and pyramid of energy is that a pyramid of biomass shows how much biomass is present in the organisms of each trophic level while a pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level. Ecological pyramids are pyramid-shaped diagrams of energy flow, biomass […]
Difference Between Miasmatic Theory and Contagionism
The key difference between miasmatic theory and contagionism is that miasmatic theory states that diseases such as cholera and chlamydia are caused by a miasma, which is a poisonous vapour or mist filled with particles from decomposed matter while contagionism is a concept that states the infectious diseases are contagious due to person to person contact or […]
Difference Between Extremophiles and Hyperthermophiles
The key difference between extremophiles and hyperthermophiles is that extremophiles are microorganisms that inhabit extreme environments such as hot niches, ice, and salt solutions, while hyperthermophiles are a category of extremophiles that thrive in extremely hot environments such as thermal vents, etc. Extremophiles are fascinating organisms that thrive in extreme environments where other terrestrial life […]
