Biology Assignment Help -Evolution Of The Cell

Online, September 21, 2012 (Newswire.com) - Thus logical next stage is to study evolution of cell how molecule became first virus and bacteria and there after Prokaryote cell and highest eukaryotic cell.

Thus Evolution of cell is important to understand and study human life as well as animal life. According to Biology assignment help All the living organisms and creator are made up of cells. A living cell may be defined as a structure enclosed by a membrane that consists of several chemical constituents and is capable of increasing itself by division. Activity of all organisms is dependent on the activities of its cells, individually or collectively.

Basic structures and functionality are common in all cells with certain differences according to their specific and peculiar needs. There are two clear stages in evolution of the cell that is chemical evolution and biological evolution. Chemical evolution started with the formation of organic molecules on the planet that had no life until then. We may call it prebiotic earth. Some of these early molecules developed the ability of producing an exact copy of their ownself by self-replication. We may say this event as the origin of life. Biology assignment help explain that in the biological evolution, molecule organised and formed the cell that was different from the cell as it exists today.

Basic understanding of chemistry is very much needed in study biology specially development of cell from molecule. Thus chemistry assignment help is very much helpful in study of complex concepts of chemistry as well as biology.

Biology homework help is very helpful in study development From Molecules to the First Cell the prebiotic conditions on the earth in all probability were very nature destructive stage like volcanic eruptions, lightning and heavy rains. There was no evidence of free oxygen or an ozone layer in the atmosphere to absorb ultraviolet radiations from the sun. It may be assumed that molecules would have originated in such climatic conditions. This may be described as their abiotic origin. Experiments from laboratory prove that organic molecules like amino acids, nucleotides, nucleic acids, lipids the and ATP can be formed in similar conditions on the earth.

Different type of tools and technology which help in discovery of cell was also very helpful in study different stage of cell evolution right from molecule to virus and bacteria and then Prokaryote cell and highest eukaryotic cell.
