Prokaryotes do not have a nuclear membrane or nucleoli, Eukaryotes do. Prokaryote have no organells, Eukaryote do. Prokaryotes usually have a single circular chromosome lacking histones. Eukaryotes have multiple linear chromosomes with histones. Prokaryotes replicate by binary fission, Eukaryotes by mitosis and meiosis.

Rafa1. Replication in prokaryotes typically proceeds in both directions from one point of origin to a termination region until there are two copies of the circular chromosome. Replication of eukaryotes has many points of origin and many bubbles (places where the DNA strands are separating and replication is occurring). This should help, came straight out of my college Biology book, good luck!
Eukaryotic cells have membrane-bound nucleus and membrane-bound organelles (mitochondria, chloroplasts) . In addition, eukaryotic cells have discrete, linear chromosomes while prokaryotes have one long circular chromosome.
Depending on how much information you need, prokaryotes have 70S ribosomes, and Eukaryotes have 80S ribosomes. In addition, prokaryotes are relatively dry cytoplasm (70% water) to eukaryotes 80% water.

What are the two basic kinds of cells?
The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
Is ribosomes in prokaryotic cells and eukaryotic cells?
Yes, ribosomes are found in both prokaryotic and eukaryotic cells. They are responsible for protein synthesis in all cells by translating mRNA into a specific sequence of amino acids to form proteins. While the basic structure and function of ribosomes are similar in both types of cells, there are some differences in the size and composition of ribosomes between prokaryotic and eukaryotic cells.
Five basic differences between respiration fermentation?
Respiration involves the breakdown of glucose with the presence of oxygen to produce ATP, while fermentation is the breakdown of glucose in the absence of oxygen, resulting in a limited amount of ATP. Respiration occurs in the mitochondria in eukaryotic cells, while fermentation occurs in the cytoplasm. Respiration produces carbon dioxide and water as byproducts, while fermentation produces lactic acid, ethanol, or other byproducts. Respiration is more efficient in ATP production compared to fermentation. Respiration is a common process in aerobic organisms, while fermentation is common in anaerobic organisms or under anaerobic conditions.
One of the basic differences between science and a pseudoscience is the lack of?
Empirical evidence and the adherence to the scientific method are key differences between science and pseudoscience. Science relies on testable hypotheses, reproducible results, and peer review to establish knowledge, while pseudoscience often lacks empirical support and relies on anecdotal evidence or unverified claims.
What are the three basic types of cells?
The three basic types of cells are prokaryotic cells (lacking a nucleus and membrane-bound organelles), eukaryotic plant cells (containing a nucleus and membrane-bound organelles), and eukaryotic animal cells (also containing a nucleus and membrane-bound organelles).
