20 Difference Between Prokaryotic And Eukaryotic Cells And Their Characteristics

Image
  Prokaryotes are derived from the Greek word in which the prefix PRO means primitive or old, whereas akaryotes mean nucleus, which evolved on earth millions of years ago. On the other hand, the word eukaryotes split into two words, in which EU means new or advanced, and akaryotes as the nucleus. Based on the functions and structure, cells are categorized as  prokaryotic and eukaryotic cells . Prokaryotic cells are simple and usually small in size, whereas eukaryotic cells have more complex parts and large structures; even the working of parts is also difficult to understand. In som e  microorganisms like bacteria, the nuclear region of the cell is partially defined due to the missing nuclear membrane within it. Such an irregular-defined nuclear region that consists of only nucleic acid or DNA molecule is known as the nucleoid. If we take a look overall at both the type of cells, eukaryotic and prokaryotic cells, besides cell wall and plasma membrane, then ribosomes are t...

11 Difference Between Reptiles And Amphibians & Characteristics

Image
Reptiles and Amphibians  are the  classes of animals that came under vertebrates; further, they are separated among orders. Both the groups of animals are closely related to each other as they tend to share few similarities, which we see in both animal types. Still, despite these similarities, there are few differences in terms of their physical appearance and life cycle stages. Reptiles originally originated from the   Latin word ‘reptilia,’ which means to “crawl.” They are also evolved from ancient animals such as Dinosaurs. They possess the most common physical features or traits that are said to be found in both the animal kingdom, namely reptiles and amphibians. In earlier times, the people also say that their kingdom or reptile land are generally evolved from amphibians due to the body structure and resemblance observed in them. Overall, vertebrates were descended from the same ancestors around some rough period of 300 million years ago. While the amphibians general...

17 Difference Between Animal cell And Plant Cell & Functions

Image
    The word “cell” originally comes from a Latin word that means tiny space rooms. This is one of the greatest discoveries of humankind in bioscience ever that took place in the year 1838 by two biologists named Schleiden and Schwann. At that time, humans get to know that all the living things in the world were made up of small units that later came to be known as cells. Meaning Animal cell and plant cell  are  c ategorized under eukaryotes as both have possessed the traits of the eukaryotic cell and i.e., one of the most common similarities that we found in these two. First of all, both animal cell and plant cell are defined as eukaryotic cells due to the nature of eukaryotes they possess within themselves. Secondly, most of the plants are multicellular and less variety is found of unicellular. Animals are too unicellular and multicellular, containing millions and trillions no. of cells in a single being. Animal Cell Endoplasmic Reticulum:  The endoplasmic ret...

15 Renewable And Nonrenewable Resources Facts You Need To Learn Now

Image
  NATURE AND MEANING When we say  renewable and nonrenewable resources  of energy, one thing comes to our mind that how the resources are extracted or what is the source of their energy, besides knowing the fact that in order to make or generate energy out of these resources, it will need a great amount of work to extract and pass energy out of the resources. We as mankind idealize the use of ener g y since the very first days, when evolution takes place in regards to humans or when early men first ignite fires accidentally with the rubbing of two stones together. On that day we came across one of the natural power in terms of fire and from that day onwards we keep on using fire in various means, so fire as raw energy is one of the greatest inventions of mankind whereas wood act as a fuel which help us in many ways. Renewable Resources: A renewable resource is available in excess quantity in our nature, and such resources will not be going to vanish from our environment i...
