Question

Do prokaryotes have rough and smooth ER?

Answer 1

Hint: Prokaryotes do not have a membrane-bound organelle. Prokaryotes, such as bacteria, do not contain membrane-bound organelles such as the nucleus, mitochondria, and chloroplasts that might be found in a eukaryotic cell.

Complete answer:
In general, prokaryotic cells are smaller and less complex cell organisms than eukaryotic cells. They do lack membrane-bound organelles (such as mitochondria) and contain a nucleoid region instead of a membrane-bound nucleus. They do have ribosomes, Only eukaryotes have ribosomes. Both prokaryotes and eukaryotes are caged in cell membranes.

One main difference between prokaryotic and eukaryotic cells is the organization and storage of genetic material. Both types of organisms use DNA in the double-helix structure. In eukaryotes, this DNA is kept as chromatin or chromosomes within the nucleus, but in prokaryotes, it is stored in a circular bundle known as nucleoid in the cytoplasm.
Prokaryotic cells differ from eukaryotic cells in that they show the absence of any membrane-bound organelles, including the nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

The rough endoplasmic reticulum, peroxisomes, and mitochondria are all bound by their own membranes and are only found in eukaryotic cells.

Note:
When comparing the prokaryotes to the eukaryotes, the main fact here to remember is that prokaryotes do not contain membrane-bound organelles. This means that they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material which is located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.
