Protozoa are single-celled eukaryotes organisms whose cells have nuclei that normally show characteristics associated with animals‚ most common mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds. Most algae are classified in the kingdoms Plantae and Chromista‚ and some the remaining forms may be classified as a kingdom Protozoa. The name is misleading‚ since they are not animals. Protozoa have traditionally

Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

p.92\ a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

prokaryotic cells origins. Prokaryotes and eukaryotes have more differences than similarities. To start comparing these two cell types‚ similarities between them should be noted. Both eukaryotes and prokaryotes are bound by a lipoprotein membrane‚ which separates the cell’s inside from outside. This way cells

The debate between whether a virus is living or nonliving has been going on for years. In order to answer this question‚ one must have background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them

normal means. It is sometimes called simple mitosis. On the other hand eukaryotes have a nucleus which contains the DNA and the information necessary to grow reproduce and function. The Information is stored in thin molecules of DNA. This is needed for cells to perform by the cell in the process of life and reproduction. One of the functions of the nucleus is to protect the DNA in the cell from becoming damaged. Prokaryotes
