In a plant, the veins of the leaf blade or lamina exhibiting the parallel pattern from the base to the tip is known as the parallel venation, on the contrary, when the veins of the leaf blade or lamina in the plants exhibit the web like or net-like pattern on both side of the midrib is known as the reticulate venation. In a leaf, the arrangement of veins is called as venation. The venation architecture is enormously distributed among the diverse species of the plants. The venation has its … [Read more...]
Difference Between Cellulose, Starch and Glycogen
These three polysaccharides differ in their glycosidic linkages and their functions too. Starting from the cellulose which is the monomer of beta glucose and is found in plant cell wall only. While Starch and Glycogen act as the carbohydrate reserve in plants and animals respectively. Though their chains have slight differences at the branching point, which is described below. We all are aware of the importance of carbohydrate, whether it is plants, animals (including humans), or … [Read more...]
Difference Between Moist Heat and Dry Heat Sterilization
When the process of sterilization is carried out at high -pressure through water (steam) it is called as moist heat sterilization, on the other hand, dry heat sterilization is carried out at high temperature under dry condition. The best way to kill microbes is through 'heat', as it destroys their proteins as well the enzymes present in them. So sterilization (destroying or killing the microbes) process follows this principle of killing microbes, which can be either by giving wet (moist) heat … [Read more...]
Difference Between Turner and Klinefelter Syndrome
Turner syndrome is the dysgenesis in the female gonads, while Klinefelter syndrome is the male hypogonadism. These can be explained by saying that both the terms are problems related to the sex chromosomes, as in the earlier one there is lacking of one of the sex chromosomes and so-called as monosomy (2n-1), while the latter consist of the extra sex chromosome and so-called as trisomy (2n+1). There are total 46 or 23 pair chromosomes in a cell of the human body, out of which 44 are said as … [Read more...]
Difference Between Nitrification and Denitrification
The biological process, where ammonium gets converted into nitrate is called nitrification. Further, when this nitrate is converted or reduced into nitrogen gas, it is called denitrification. These steps involve various microorganisms, and it is important biologically as well as economically. Both the steps are a significant part of the nitrogen cycle, which is one of the most important cycles for our atmosphere. Around 78% of the atmosphere contains nitrogen, which is even an essential … [Read more...]
Difference Between Monocotyledons (monocots) and Dicotyledons (dicots)
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...]
