Difference Between Gram Positive and Gram Negative Bacteria

Last updated on February 5, 2018 by Divanshi G

The gram-positive bacteria retain the crystal violet and stain purple, while the Gram-negative bacteria lose the crystal violet and stain red from the safranin counterstain. So by Gram-staining technique and the color they retain is crystal violet or not describes the features of the bacteria, as well they are characterized as positive or negative. The word 'gram-staining' technique arose from the Danish bacteriologist Christian Gram in 1884. This stain is a weak alkaline solution of a … [Read more...]

Difference Between Plasma and Serum

Last updated on September 15, 2017 by Divanshi G

Plasma is that part of the blood, which contains blood clotting agent called as fibrinogen, while serum is the fluid part of the blood and does not contain clotting agent. The plasma and serum can be extracted from the centrifugation of blood. The serum is obtained after the clotting of blood, while plasma can be obtained before the coagulation of the blood. Centrifugation separates the blood components by its weight, size, and density. The fluid circulating in the body through arteries and … [Read more...]

Difference Between C3, C4 and CAM pathway

Last updated on September 15, 2017 by Divanshi G

The assimilation of carbon dioxide from the sunlight, for the process of photosynthesis and then converting it to glucose (energy) synthesizing different product is the key difference between the three. So during the CO2 fixation, when the photosynthetic plants produce 3-phosphoglyceric acid (PGA) or 3- carbon acid as the first product is called C3 pathway. But when the photosynthetic plant, prior going to the C3 pathway, produces oxaloacetic acid (OAA) or 4 -carbon compound as their first … [Read more...]

Difference Between Osteoarthritis and Rheumatoid arthritis

Last updated on September 15, 2017 by Divanshi G

Nature and the cause are the main difference between the osteoarthritis and rheumatoid arthritis. Osteoarthritis is the kind of degenerative condition, while rheumatoid arthritis is a kind of autoimmune disease, where the body itself attacks the body's joints. Osteoarthritis is due to the increased wear and tear on joints, whereas rheumatoid arthritis produces the inflammation of the joints throughout the body, also resulting in fever and severe fatigue. There are many forms of arthritis like … [Read more...]

Difference Between Aerobic and Anaerobic Respiration

Last updated on May 14, 2019 by Divanshi G

Aerobic denotes the term 'in the presence of oxygen' while the word anaerobic denotes the 'absence of oxygen'. So the respiration which occurs in the presence of oxygen is called as aerobic respiration, on the other hand, respiration occurring in the absence of oxygen is known anaerobic respiration. So accordingly the chemical reaction involving the breakdown of the nutrient molecule with the aim of producing energy is called respiration. Thus the energy required by the body to perform well … [Read more...]

Difference Between Osmosis and Diffusion

Last updated on February 16, 2022 by Divanshi G

Osmosis and Diffusion both depict the movement of particles from higher concentration to lower concentration. However, osmosis is a type of diffusion that is limited to fluids. Whereas, diffusion is not restricted and is prevalent in solids, liquids and gases. The passage of the solvent molecules in osmosis occurs through a selectively permeable membrane. In contrast, for diffusion, the membrane is not mandatory. It can spread the particles directly within the given medium. Osmosis … [Read more...]

Difference Between Abiotic and Biotic Factors

Last updated on March 29, 2022 by Divanshi G

We can divide the ecosystem into two main categories: abiotic and biotic, based on whether they are living or non-living. Our ecosystem acts as a platform that portrays the interaction between the biotic and abiotic factors. The biotic factors include the living components that can grow, survive and adapt. Whereas the abiotic factors are simply the non-living elements of the environment. They tend to impact the rate of growth, survival and adaptation of the biotic components. Thus, you can … [Read more...]

Difference Between Heterochromatin and Euchromatin

Last updated on May 14, 2019 by Divanshi G

The major difference between heterochromatin and euchromatin is that heterochromatin is such part of the chromosomes, which is a firmly packed form and are genetically inactive, while euchromatin is an uncoiled (loosely) packed form of chromatin and are genetically active. When the non-dividing cells of the nucleus were observed under the light microscope, it exhibited the two regions, on the ground of concentration or intensity of staining. The dark stained areas are said as heterochromatin … [Read more...]

Difference Between Bones and Cartilage

Last updated on February 2, 2022 by Divanshi G

Both bones and cartilages are connective tissues. But they vary in their structures and functions. Bones on one hand are harder, solid and rigid structures. Their primary function is to provide structure and stability to the body. They also protect the internal organs from getting injured. While the cartilages are soft and flexible tissues. They are present between two bones to support joints. Also, they reduce the impact of friction while moving. The cells of bones are osteocytes and … [Read more...]

Difference Between Hepatitis and Jaundice

Last updated on September 15, 2017 by Divanshi G

Hepatitis is said to be the inflammation of the liver cells due to the attack of virus, bacteria, parasites, drugs, ischemia, toxins, etc. On the other hand, when there is surplus deposition of the bile pigment in blood especially of bilirubin, resulting in the yellow discoloration of the eye (sclera), skin, it is called as Jaundice. Hepatitis is the liver disease, while jaundice is a sign of the increased production of a yellow pigment called bilirubin in the blood. Hepatitis and jaundice … [Read more...]
