Cilia are short, hair-like structure, present in large numbers in a cell, while flagella are long, hair-like complex structure and are few per cell. Cilia and flagella are hair-like appendages, extending through the surface of the living cell, they differ in their mode of beating, size, and number. Cilia and flagella are the locomotory structure, which is the extension of the plasma membrane of the cell. Besides the locomotion, they also help in other processes like respiration, excretion, … [Read more...]
Difference Between Asthma and Chronic Obstructive Pulmonary Disease (COPD)
The respiratory disease which is diagnosed during childhood, resulting in shortness of breathing, dryness of a cough, chest tightening is called asthma. On the other hand, COPD also known as Chronic Obstructive Pulmonary Disease is also one of the respiratory disease, which occurs after the age of 4o, and the condition gets progressively worse with age. The cell's of our body need oxygen to work and grow, and this oxygen is taken by the lungs through the simple process of breathing. Usually, … [Read more...]
Difference Between Primary Metabolites and Secondary Metabolites
Metabolism involves a whole set of biochemical reactions constantly occurring inside a living body to keep it alive and active. The metabolites are the intermediate compounds or end products generated as a result of these metabolic transformations. We can categorise the metabolites in two parts based on their origin and function- Primary and Secondary metabolites. The primary metabolites directly influence the vital process like growth, development and reproduction of any organism. In … [Read more...]
Difference Between Primary Succession and Secondary Succession
Primary Succession can be defined as the process of growth in an area that was previously uninhabited, barren, unoccupied and there was no initial vegetation. On the other hand, Secondary Succession can be defined as the growth of the community in such area which was previously occupied, inhabited and that has primary vegetation but got disturbed or damaged due to some external or internal factors. The example of Primary Succession is the newly formed bare rock, desert, ponds, etc., while the … [Read more...]
Difference Between Nervous System and Endocrine System
The significant difference between these two is that the nervous system uses electrical signals or impulses to send the signals through neurons, while the Endocrine system uses hormones acting as the chemical messenger to send signals to the target cell through the blood stream in the body. However, both are the regulatory system allows the communication between the tissue, organs, and cells. These systems have the responsibility to control and coordinate the signals given to the body, … [Read more...]
Difference Between Gram Positive and Gram Negative Bacteria
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
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
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
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
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...]
