These are the two types of blood pressure, controlled by the beating of the one's heart. The heart is the organ which provides oxygenated blood to all tissues, organs and other body parts. For pumping the blood the heart contracts and relax continuously and … [Read more...]
Difference Between Parenchyma, Collenchyma and Sclerenchyma Cells
Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant. Likewise the humans, who have bones to support their body structure, plants also have certain specialized tissues which help them, by providing … [Read more...]
Difference Between Hibernation and Aestivation (Estivation)
The state of inactivity and a low metabolic process performed by the animals during the winters is known as Hibernation. It is also known as winter sleep. On the contrary, when animals take rest in shady and moist place during summer, it is called Aestivation or Estivation. Aestivation is also known as summer sleep. The importance of these sleep is mainly related to the conservation of energy of one's body, survival during the extremes temperature, scarcity of food and water, etc. These sleep … [Read more...]

Difference Between Oviparous and Viviparous Animals
Birds, insects, reptiles, amphibians, and fish falls under the category of oviparous, as they lay eggs and give rise to more of their kind, in order to increase their generation. While mammals like humans, cats, dogs, lions, tigers, etc are said as the viviparous, as they directly give birth to the young ones. Fertilization is the union of two nuclei, one is of paternal origin and the other is from the maternal origin which finally fuses to form an embryo. There are different patterns of … [Read more...]
Difference Between Mutation and Variation
The changes in the nucleotide sequence at the DNA level or in any one of the base pairs is known as mutation, while the genetic variation is how one individual of a species variate from another, variation can be due to changes in the nucleotide sequence like insertions, deletions, any genetic rearrangements or any environmental factors. We all are aware of the DNA, RNA which are said as the genetic material and consist of the codes or bases A, C, G and T, and their combinations make the … [Read more...]
Difference Between Self-Pollination and Cross-Pollination
The process of transfers of pollen grains from anthers to the stigma of a flower, but when this process is between the flowers of the same plant than the term is called as self-pollination, while when the transfers are between the flowers of the different plant of same species is called as cross-pollination. Secondly, pure line progeny is obtained in the self-pollination. The target of every living organisms is to create their young ones and transfer their characters to them. Pollination is … [Read more...]

Although biota is the term used for complete forms of life like fungi, bacteria, etc. Flora and Fauna are scientific words, in general, we use the term plants … [Read more...]
Difference Between Bacteria and Fungi
Bacteria and Fungi come under different categories; the former one is the prokaryotic cell while the latter one is Eukaryotic cells. Apart from this, there are many differences between them like bacteria need a host to live, and they can be autotrophs as well as heterotrophs, whereas fungi grow their own and are heterotrophs which depend on others for their food. Bacteria do not have nuclear membrane enclosing nucleus, while Fungi (eukaryotes) have well- defined nucleus surrounded by the nuclear … [Read more...]
