fundamental structure of their cells. These two groups are the prokaryotes and the eukaryotes. A Prokaryote cell is the first form of cells for many millions of years until the eukaryote cell evolved from the prokaryote cell‚ which created life. Prokaryote cells are organisms made up of cells which lack a cell nucleus or any membrane encased organelles‚ which means the DNA in prokaryotes is not bound with a nucleus. In the eukaryotes‚ DNA is organized into chromosomes‚ which is surrounded by a membrane. According

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

Compare and contrast the Five kingdom and three domain classification system Classification is the method used by scientists to order living organisms. All species have a unique classification that results in a binomial name. classification is used to make it easier for different species to be identified by scientists. The current system‚ the Three Domain System ‚ groups organisms primarily based on differences in ribosomal RNA structure. Ribosomal RNA is a molecular building block for ribosomes

List 2 different ways living organisms accomplish each of the 5 features above. (the focus here is to recognize how living things differ from one another) We divide Earth’s biodiversity into broad groups based on traits such as having a nucleus (eukaryotes)‚ not having a nucleus (prokaryotes)‚ or being unicellular or multicellular. 4.

they must parasitize cells in order to translate their own genetic code and reproduce themselves. Cells are of two distinctly different types‚ prokaryotes and eukaryotes; thus‚ the living world is divided into two broad categories. The DNA of prokaryotes is a single molecule in direct contact with the cell cytoplasm‚ whereas the DNA of eukaryotes is much greater in amount and diversity and is contained within a nucleus separated from the cell cytoplasm by a membranous nuclear envelope. Many eukaryotic

Without the mitochondria being engulfed by other single – celled eukaryotes‚ then life on earth wouldn’t be as evolved as it is now. From reading this book‚ it was in a way that if you don’t know too much about the mitochondria‚ you will be confused. After a few times of reading the same section of the book‚ you’re able

Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi. The sexual cycles of many Protista are unknown‚ but most are thought to have some process of genetic recombination. Unicellular Protista

Cells are the smallest unit of life that can replicate independently. Often they are called “building blocks of life”. There are two branches of cell types‚ the eukaryotes and the prokaryotes[1]. Eukaryotes contain organelles that are bound in a cell membrane‚ including a nucleus bounded by a double membrane structures‚ this is where the DNA is located. Prokaryotes do not contain organelles bound in a membrane structure‚ so there is
