Prokariotico

Prokariotico refers to a type of cell that lacks a membrane-bound nucleus and other membrane-bound organelles. This means that the genetic material, deoxyribonucleic acid (DNA), is not enclosed within a distinct nucleus but rather floats freely in the cytoplasm in a region called the nucleoid. Prokaryotic cells are generally simpler and smaller than eukaryotic cells, which possess a true nucleus and specialized internal compartments.

The two primary domains of life that consist of prokaryotic organisms are Bacteria and Archaea. These organisms are found in virtually every environment on Earth, from soil and water to extreme conditions like hot springs and deep-sea vents. Despite their structural simplicity, prokaryotes exhibit remarkable metabolic diversity and play crucial roles in ecosystems, including nutrient cycling and decomposition.

Key features of prokaryotic cells include a cell wall, which provides structural support and protection, and a cell membrane that regulates the passage of substances into and out of the cell. Many prokaryotes also possess ribosomes, the cellular machinery responsible for protein synthesis. Some prokaryotes have external structures like flagella for motility or pili for attachment to surfaces or other cells. Reproduction in prokaryotes typically occurs through asexual processes, most commonly binary fission, where a single cell divides into two identical daughter cells.
