adoptions to solely changing environment and conditions. In other situations dramatic changed in the conditions seem to force sudden and noteworthy changes to the evolution. And sometimes‚ a gigantic event makes a big splash in evolution. The origin of eukaryotes appears to have been a big splash in the form of endosymbiosis‚ a condition in which different organisms live together. The idea that endosymbiosis has been around since 1905 when a Russian biologist‚ C. Mereschkowsky‚ hypothesized that plastids

their relatively simple levels of organization‚ the protists do not have much in common.[3] They are unicellular‚ or they are multicellular without specialized tissues‚ and this simple cellular organization distinguishes the protists from other eukaryotes‚ such as fungi‚ animals and plants. The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally subdivided into several groups based on similarities to the "higher" kingdoms: the unicellular "animal-like" protozoa‚ the

WHAT IS A CELL? It is the smallest unit of life that is classified as a living thing‚ and is often called the building block of life. The cell is the basic structural and functional unit of all known living organisms. Some organisms are unicellular (made of only one cell) while others are multicellular (made up of several cells). The word cell comes from the Latin cellula‚ meaning‚ a small room. The term was coined by Robert Hooke in a book he published in 1665 when he compared the cork cells he

Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the arrangement of chromosomal DNA. Prokaryotes

from the cells of wheat germ there are seven steps to follow. The optimal cell to use would be the polyploidal eukaryotic. Eukaryotes have nucleus membrane-bound organelles‚ while prokaryotic does not. The polyploidal eukaryotic cell has DNA that is held in the nucleus while the prokaryote has DNA that floats freely around the cell. The DNA of eukaryotes is more complex and extensive than the other. Prokaryote is a bacterial cell that usually has DNA in one large strand and

No nucleus is called prokaryotes. * Prokaryotes examples are archae and bacteria. * Eukaryotes tend to be more complex and larger. They include plants‚ animals‚ and fungi and other groups. * DNA gets transcribe to mRNA leaves the nucleus and it gets translated into proteins in the
