Prokaryotic Cells
Prokaryotic cells are simple, single-celled organisms that lack a defined nucleus and other membrane-bound organelles. Their genetic material, usually a single circular chromosome, floats in the cell's cytoplasm. Prokaryotes include bacteria and archaea, which are known for their ability to thrive in diverse environments. Unlike eukaryotic cells, which are found in plants, animals, and fungi, prokaryotic cells are generally smaller and reproduce quickly through a process called binary fission. Despite their simplicity, they play essential roles in ecosystems, such as decomposing organic material and contributing to nutrient cycles.

Prokaryotic cells are simple, single-celled organisms without a nucleus. They are smaller and less complex than eukaryotic cells, which do have a nucleus. Prokaryotes include bacteria and archaea. Their genetic material, DNA, floats freely in the cell rather than being contained within a membrane-bound nucleus. Prokaryotic cells have a cell wall, cell membrane, and may possess structures like flagella for movement. They reproduce asexually, usually by dividing in half. Prokaryotic cells are crucial for ecosystems, playing roles in nutrient cycling, decomposition, and even human health.
