List 2 ways in which prokaryotic and eukaryotic cells are alike and 2 ways in which they are different.

Is this correct?
Alike= cell membrane and DNA
Different=ribosomes and mitochondria

Actually their DNAs are not necessarily alike. The DNA of eukaryocytes are enclosed with an endomembrane while the prokaryocytes' are not.

The fact that they both have DNA is a similarity but the DNA does actually differ in that like Amy said above and that prokaryotic DNA is linear and eukaryotic DNA is typically circular wrapped around histone proteins. And prokaryotic cells do not have organelles in general, not just ribosomes and mitochondria.

You are partially correct! Prokaryotic and eukaryotic cells do have some similarities and differences.

Similarities:
1. Cell Membrane: Both prokaryotic and eukaryotic cells have a cell membrane, also known as a plasma membrane, which acts as a barrier between the cell and its environment. The cell membrane controls the movement of substances in and out of the cell.
2. DNA: Both types of cells contain genetic material in the form of DNA (deoxyribonucleic acid) that carries the instructions for the cell's structure and function. However, there are some differences in the organization and location of DNA in these cells.

Differences:
1. Ribosomes: One significant difference between prokaryotic and eukaryotic cells is the structure and location of ribosomes. Prokaryotic cells have smaller ribosomes (70S) compared to eukaryotic cells (80S), and they are not membrane-bound. In eukaryotic cells, the ribosomes are either found free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER).
2. Organelles: Another significant difference lies in the presence of membrane-bound organelles within eukaryotic cells, while prokaryotic cells lack such complex, membrane-bound structures. Eukaryotic cells possess various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and nucleus, which play vital roles in different cellular functions. Prokaryotic cells lack these specialized membrane-bound compartments.

It is important to note that these are just a few examples, and there are more similarities and differences between these two types of cells.
