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)
Hibernation and aestivation are the forms of sleeping states which occurs under two different climate conditions. Both of them are extended forms of torpor. Sometimes, the animals fall asleep to survive in harsh and extreme environments. This sleeping pattern may vary as per the climate and the growth phases of the organism. The primary difference between hibernation and aestivation is that the former is winter sleep while the latter is summer sleep. During extremely low temperatures, … [Read more...]
Difference Between Plants and Animals
Plants and animals are easy to differentiate by their appearance and unique characteristics. Plants are the only living entity that has the potential for photosynthesis. And thus they are the most precious pillar of the ecosystem. They use the naturally available raw stuff like water and carbon dioxide to prepare carbohydrates. For this reaction, the sunlight acts as an energy source that is trapped by chlorophyll. In contrast, animals are devoid of photosynthetic ability. This is because … [Read more...]
Difference Between Oviparous and Viviparous Animals
We can classify the animals into two categories- Oviparous and Viviparous, based on how they produce their new generation. Oviparous animals are those which lay either fertilized or unfertilized eggs that hatch to give rise to a new young one. Whereas the viviparous are the animals that directly give birth to their younger ones. In oviparous animals, the development of the zygote occurs outside the body. The developing embryo takes the nutrients from the Yolk present inside the egg. In … [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
Based on the movement of pollen from anther to stigma, we can categorise the pollination process into two categories- Self and Cross-Pollination. At the time of self-pollinations, the pollen travels from stigma to anther of the flower of the same plant. Whereas during cross-pollination, these movements occur between the anther and stigma of two different plants. Self-pollination is a simple and straightforward process. It occurs in about 1/4th plant species of the earth. In comparison, … [Read more...]
Difference Between Cyst and Tumor
The small outgrowth or pouch kind of lump found beneath the skin is known as the cyst, while a tumour is an abnormal growth or mass or swelling of tissues. Identifying lump or bump under the skin area is quite disturbing, but these are not always harmful. The two most common types of lumps are cyst and tumours. Though it is difficult to differentiate them, as these are found almost in same places of the body like one can have ovarian cysts as well as ovarian tumours. With the development … [Read more...]
Difference Between Flora and Fauna
Flora is the term used for studying the plant's life living in a particular area or region, whereas fauna refers to the study of animals life living in any geographical area. Secondly, all kinds of grasslands, trees, plants, comes under flora, on the contrary, all types of animals, birds, and insects fall under the category of fauna. 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...]
Difference Between Covalent, Metallic and Ionic Bonds
Covalent bond occurs between the two non-metals, metallic bond occurs between two metals and the ionic bond occurs between the metal and the non-metal. Covalent bond involves the sharing of electrons, while metallic bonds have strong attractions and ionic bonds involve the transferring and accepting of electrons from the valence shell. The adhering property of an atom, in order to arrange themselves in a most stable pattern by filling their outermost electrons orbit. This association of atoms … [Read more...]
