The seed in the plant having one cotyledon is called as the monocotyledon, while the seed in the plant having two cotyledons is named as the dicotyledon. Ginger, banana, wheat, maize, palm, onion, garlic are few examples of monocotyledonous plants, while rose, groundnut, potato, tomato, pea, eucalyptus, hibiscus are the examples of dicotyledonous plants. Knowing the family of a plant is useful in many ways, as it helps us to know many factors about plant and how will it germinate, what kind … [Read more...]
Difference Between Internal and External Fertilization
Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies. Internal fertilization is followed by mammals, birds, while external fertilization is supported by mostly aquatic animals and few amphibians. We all are aware of the word fertilization, which defines … [Read more...]
Difference Between Archaea and Bacteria
Despite being in the same category of prokaryotes, archaea and bacteria show variances in their genetic makeup, as the metabolic pathways, and other enzymes, genes possessed by the archaea closely resembles eukaryotes rather bacteria. Simple, microscopic, ambiguous microorganisms mark their presence universally, whether its deep in water, high temperature, soil or any extreme conditions. The evolving history of these cells is considered to be old as more than 3.5 billion years ago. Archaea … [Read more...]
Difference Between Endothermic and Exothermic Reactions
We classify the chemical reactions as endothermic or exothermic, depending on whether it is giving energy or taking energy. The endothermic reactions are when the system takes up the energy in the form of light or heat. In contrast, exothermic systems give up heat or light energy as the reaction proceeds. In endothermic processes, reactants possess lower potential energy than the product. Thus, in order to react, they absorb the energy from the environment. Due to this, the change in the … [Read more...]
Difference Between Voluntary and Involuntary Muscles
Voluntary muscles or striated muscles are those which work according to the one's desire or are under control, whereas Involuntary muscles are not under one's control. Biceps muscles, respiratory, alimentary and urogenital tracts are the places where voluntary muscles are found, while abdominal muscles, locomotory muscles, middle ear muscles, Diaphragm are the examples of the involuntary muscles. Locomotion and movement are the main features of the organisms, whether it is unicellular or … [Read more...]
Difference Between Mitochondria and Chloroplast
Mitochondria are known for generating energy for the cell in the form of ATP (adenosine triphosphate) by using nutrients and oxygen. The chloroplast is present in green plants and few algae, they are known as the place, where the process of photosynthesis occurs. In the cell of the eukaryotes, there are only three organelles, which are bounded by the double membrane structure - the nucleus, the mitochondria, and the chloroplast. There is the higher level of diversity on the surface of the … [Read more...]
Difference Between Arteries and Veins
Arteries carry oxygenated blood away from the heart, these are the thick-walled muscular tube, while Veins carry deoxygenated blood towards the heart. Though both have the exception of the pulmonary artery and vein, as here the system get opposite and the pulmonary artery carries the deoxygenated blood, and pulmonary vein carries oxygenated blood. Among the two types of circulatory system - Open circulation and Closed circulation. In vertebrates, closed type of circulatory system is found, … [Read more...]
Difference Between CT Scan (Computed Tomography) and MRI (Magnetic Resonance Imaging)
CT Scan uses harmful x-rays ( the form of electromagnetic radiation like light) for imaging, while MRI does not use any radiation and is based on the effect of the magnetic field, radio waves for the imaging of the organs of the body. CT Scan gives the images of the bones in a much-sophisticated way than the x-ray and is good to check the fractures, tumors, and arthritis but MRI which is popular in detecting the damage of soft tissue. It is also seen that CT Scan is not as expensive as the … [Read more...]
Difference Between Tendons and Ligaments
Tendons attach or support the joints between muscles and bones, while ligaments support the joints between bones. Tendons are strong and non-flexible, whereas ligaments are flexible and elastic. Both being the part of the musculoskeletal system, play the vital role in the joints and bones and thus responsible for all kinds of movements in the body. As we all know that the human body consists of 206 bones, these bones are composed of movable and non-movable joints of the bones. These bones are … [Read more...]
Difference Between Red blood cells (RBC) and White blood cells (WBC)
RBC or Red blood cells play the vital role in carrying oxygen to the tissues of different parts of the body. Conversely WBC or White blood cells help in the defense mechanism of the body by creating antibodies. Secondly, RBC contains hemoglobin, which gives the red color to the blood and occupies around 45-50% of the total volume of the blood, while WBC is colorless, due to the absence of hemoglobin in them and comprises only 1% of the total volume of the blood. Red blood cells, White blood … [Read more...]
