Evolution may evolve through many mechanisms like mutation, migration, genetic drift but natural selection is the most famous and the most strongly accepted one. While Artificial selection involves unnatural selection or selective breeding, with the interference of humans activity. In Natural selection fittest organism is selected naturally, which is able to cope up and is adaptable to all kind of situations like variations in weather, temperature, shelter, gaining of nutrition, genetic … [Read more...]
Difference Between Habitat and Niche
Habitat is a set of the place of environmental conditions in which particular organism lives and adapt the situation accordingly. A niche is nothing but an idea or role played by organisms that how they can live in an environment including their diet, shelter, etc. Mainly niche is concerned with the factor of gaining energy by organisms and supplying it to other, in the ecosystem. A habitat defines the interaction of organisms with the other factors, which can be living or non-living, while … [Read more...]
Difference Between Haemoglobin and Myoglobin
The capability of the binding oxygen molecule, with the heme proteins, is what makes a difference in both the molecules. Haemoglobin is called as tetrameric hemoprotein, while myoglobin is called monomeric protein. Haemoglobin is found systematically all over the body, while myoglobin is found in muscles tissues only. Haemoglobin is made of protein and prosthetic group and is well known for carrying oxygen pigment. It is the most vital part to sustain life as it works in transporting oxygen … [Read more...]
Difference Between Epithelial and Connective tissues
Epithelial tissue is present just below the basement membrane, while connective tissues are found all around the body, along with the nervous system, separating and supporting the various tissues and organs. Epithelial and connective tissues are among four of the major and vital kinds of animal tissues. Mainly there are three types of epithelial tissues, based on their shapes: simple, columnar and cuboidal, and are also classified on the basis of organization of layers of cells present which … [Read more...]
Difference Between Chlorophyll and Chloroplast
Chlorophyll is the food producers of the cell found in green plants, they are present inside the chloroplast. Chlorophyll plays a vital role in turning plants green and healthy. While chloroplast is a unique organelle found in all green plants and is the location of photosynthesis to occur where the green plants can convert sunlight into chemical energy. Chlorophyll is found in the mesophyll cells in green plants leaves. The chloroplast is found in the dense fluid part of the chloroplast. The … [Read more...]
Difference Between Heterotrophs and Autotrophs
Plants, algae and few bacteria are said to be autotrophic as they are able to prepare their own food, with the help of sunlight, air, and water. Conversely animals like cow, dog, lion, horse, etc. are said to be heterotrophic as they cannot prepare their own food and depends directly or indirectly on others for their nutrition. The mode of nutrition acquired by the living organisms or the way organisms consume their food, they are divided into two main categories, which are Heterotrophic and … [Read more...]
Difference Between Meningitis and Encephalitis
Meningitis is the inflammation of the protective layer surrounding the brain while Encephalitis is the inflammation of the brain itself, this is the only minor though the important difference between the two. Meningitis and Encephalitis are the two main kinds of neurological conditions related to the brain and spinal cord, where the layer surrounding the brain get less or more inflamed. Both the medical conditions are among the scariest one affecting the nervous system. The main cause can be … [Read more...]
Difference Between Pinocytosis and Phagocytosis
Phagocytosis means "cellular eating" while Pinocytosis means "cellular drinking". Pinocytosis and Phagocytosis are the two categories of Endocytosis. Both are the active process and requires energy (ATP) as adenosine triphosphate for the uptake of materials. Phagocytosis is an intake of solid particles with the formation of vesicles called phagosomes, while pinocytosis is the intake of liquid particles with the formation of vesicles called pinosomes. The term 'Endocytosis' was given by … [Read more...]
Difference Between Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA)
DNA and RNA are the two types of nucleic acids that act as the hereditary material to transfer genetic information from one generation to the next one. They store the inherited data in them, thus can be considered as the repositories for the genetic information. DNA (double-stranded) as a genetic transporter is present in almost all the higher eukaryotic organisms. Whereas RNA (single stranded) as genetic material is found only in lower organisms like prokaryotes. Eukaryotes too have a large … [Read more...]
Difference Between Plasma Membrane and Cell Wall
Plasma Membrane is the phospholipid layer, found in all types of cells; it helps in protecting the protoplasm and checks the passage of molecules inside the cell, Though cell wall is found in the plant cell, fungi, bacteria only and protects the cell from external shocks, and provide rigidity and shape to the cell. The cell wall is the outermost boundary of the cell (if present), and plasma membrane is present in the inner lining of the cell. The plasma membrane is delicate thin layer while … [Read more...]
