Answer:Prokaryotic cells make up the organisms found in the two Kingdoms of life known as Bacteria and Archaea.
there are cells without a nucleus, which are called prokaryotes. They are a group of organisms which lack a cell nucleus. The organisms with this type of cell are called prokaryotic organisms or prokaryotes. These organisms were the first to be found in the planet Earth.
A prokaryotic cell is mostly composed of a plasma membrane, cell wall, cytoplasm, genetic material in the nucleoid and ribosome. They are single-celled and are much smaller compared to eukaryotic cells. They exist in different shapes including spherical, rod, flat, coccus, spirochete, and some are also shapeless, not having a consistent shape.
Explanation:
They are well at surviving because of their thick white coat. The white fur helps them blend in with the snow and ice. The polar bear also has a layer of fat under their skin so they can survive harsh temperatures.
