Animal cells lack the rigid cell walls that characterize plant cells. The bodies of most animals (all except sponges) are made up of cells organized into tissues, each tissue specialized to some degree to perform specific functions. In most, tissues are organized into even more specialized organs. Most animals are capable of complex and relatively rapid movement compared to plants and other organisms. Most reproduce sexually, by means of differentiated eggs and sperm. Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material. The development of most animals is characterized by distinctive stages, including a zygote, formed by the product of the first few division of cells following fertilization; a blastula, which is a hollow ball of cells formed by the developing zygote; and a gastrula, which is formed when the blastula folds in on itself to form a double-walled structure with an opening to the outside, the blastopore. Online journals follow a systematic pattern with a particular style which is universally followed to avoid confusion. All the information should be unbiased, readily proven and can be challenged in any kind of situation. Each and every fact should be made clear by providing proper evidence thereby encouraging true scholar and safeguarding copyrights. Following such stringent rules and evaluation can be costly, so publishers charge from the users who access the information, but, it will obstruct research as young researchers can afford it. Alternatively, fees can be charged from the researcher who has made the research and it can be free to the user who is interested in research thus, increasing the popularity and reputation to scholar and enhancing knowledge to user.
