A different type of flagellum is found in archaea and a different type is found in eukaryotes. Fimbria A fimbria also known as a pilus is a short, thin, hair-like filament found on the surface of bacteria.

Fimbriae, or pili are formed of a protein celula prokaryote ed eukaryote pilin antigenic and are responsible for attachment of bacteria to specific receptors of human cell cell adhesion.

There are special types of specific pili involved in bacterial conjugation. Cellular processes Prokaryotes divide by binary fissionwhile eukaryotes divide by mitosis or meiosis.

Cell division Cell division involves a single cell called a mother cell dividing into two daughter cells. This leads to growth in multicellular organisms the growth of tissue and to procreation vegetative reproduction in unicellular organisms. Celula prokaryote ed eukaryote cells divide by binary fissionwhile eukaryotic cells usually undergo a process of nuclear division, called mitosisfollowed by division of the cell, called cytokinesis.

A diploid cell may also undergo meiosis to produce haploid cells, usually four. Haploid cells serve as gametes in multicellular organisms, fusing celula prokaryote ed eukaryote form new diploid cells.

DNA replicationor the process of duplicating a cell's genome, [3] always happens when a cell divides through mitosis or binary fission. This occurs during the S phase of the cell cycle. In meiosis, the DNA is replicated only once, while the cell divides twice. DNA replication only occurs before celula prokaryote ed eukaryote I.

DNA replication does not occur when the cells celula prokaryote ed eukaryote the second time, in meiosis II. This RNA is then subject to post-transcriptional modification and control, resulting in a mature mRNA red that is then transported out of the nucleus and into the cytoplasm peachwhere it undergoes translation into a protein.

Cell (biology)

Newly synthesized proteins black are often further modified, such as celula prokaryote ed eukaryote binding to an effector molecule orangeto become fully active.

Cell growth and Metabolism Between successive cell divisions, cells grow through the functioning of cellular metabolism. Cell metabolism is the process by which individual cells process nutrient molecules.

Metabolism has two distinct celula prokaryote ed eukaryote Complex sugars consumed by the organism can be broken down into simpler sugar molecules called monosaccharides such as glucose.

Once inside the cell, glucose is broken down to make adenosine triphosphate ATP[3] a molecule that possesses readily available energy, through two different pathways. Protein celula prokaryote ed eukaryote Main article: Protein biosynthesis Cells are capable of synthesizing new proteins, which are essential for the modulation and maintenance of cellular activities.

Prokaryote

Protein synthesis generally consists of two major steps: The ribosome mediates the formation of a polypeptide sequence based on the celula prokaryote ed eukaryote sequence. The new polypeptide then folds into a functional three-dimensional protein molecule.

Motility Unicellular organisms can move in order to find food or escape predators. Common mechanisms of motion include flagella and cilia.
