Where does RNA and protein synthesis take place in prokaryotes and eukaryotes?
In prokaryotes, RNA synthesis and protein synthesis takes place in the cytoplasm. In eukaryotes, RNA is produced in the cells nucleus and then moves to the cytoplasm to play a role in the production of protein.
What are the characteristics of prokaryotic?
Cells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes. Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. Bacterial cells are very small, roughly the size of an animal mitochondrion (about 1-2µm in diameter and 10 µm long). Prokaryotic cells feature three major shapes: rod shaped, spherical, and spiral. Instead of going through elaborate replication processes like eukaryotes, bacterial cells divide by binary fission. Diagram of a prokaryotic cell. Notice the internal organelles are not easily distinguishable. Bacteria perform many important functions on earth. They serve as decomposers, agents of fermentation, and play an important role in our own digestive system. Also, bacteria are involved in many nutrient cycles such as the nitrogen cycle, which restores nitrate into the soil for plants. Unlike eukaryotic cells that depend on oxygen for their metabolism, prokaryotic cells enjoy a diverse array of metabolic functions. For example, some bacteria use sulfur instead of oxygen in their metabolism.They are usually very small in size as compared to eukaryotic celles

What what are ribosomes?
Ribosomes are amongst the smallest organelles in a cell with a size of about 20 nanometers. Despite its small size compared to other organelles, it constitutes of complex and large molecules of RNA and proteins, which play vital roles in the process of protein synthesis. These complex RNA and proteins are collectively referred to as ribonucleic proteins.Ribosomes are present in all the living cells including both prokaryotes and eukaryotes. However, prokaryotic and eukaryotic ribosomes differ structurally with each other. Prokaryotic ribosomes are 70S while eukaryotic ribosomes are 80S. Ribosomes are predominantly found attached to RER (rough endoplasmic reticulum) and rarely as free organelles in the cytoplasm. However, the attachment of ribosomes with RER is not permanent since the attachment is in a state of attached and detached with RER surface.
Why are humans eukaryotes?
Eukaryotic cells are about 15 times wider than a typical prokaryote and can be as much as 1000 times greater in volume. The major difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place. Most important among these is acell nucleus, a membrane-delineated compartment that houses the eukaryotic cell's DNA. This nucleus gives the eukaryote its name, which means "true nucleus." Other differences include:The plasma membrane resembles that of prokaryotes in function, with minor differences in the setup. Cell walls may or may not be present.The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated withhistone proteins. All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. Some eukaryotic organelles such as mitochondria also contain some DNA.Many eukaryotic cells are ciliated with primary cilia. Primary cilia play important roles in chemosensation,mechanosensation, and thermosensation. Cilia may thus be "viewed as sensory cellular antennae that coordinate a large number of cellular signaling pathways, sometimes coupling the signaling to ciliary motility or alternatively to cell division and differentiation."[7]Eukaryotes can move using motile cilia or flagella. The flagella are more complex than those of prokaryotes.
Are there prokaryotic cells and eukaryotic cells in enzymes?
No, quite the opposite. There are enzymes in cells (both prokaryotic and eukaryotic). Enzymes play a role in cells - not the other way around.
What role do membrane play in prokaryotic cells in eukaryotic cell?
In Prokaryotic cells, membrane controls what enters and leaves the cell, they also give the cell a shape and keep organells together.
What role do membranes play in prokaryotes?
Prokaryotic cells do not have membrane bound organelles. The membrane controls the movement in and out of the cell.
What role do cell membrane play in prokaryotic cell In eukaryotic cell?
In Prokaryotic cells, membrane controls what enters and leaves the cell, they also give the cell a shape and keep organells together.

Are microtubules found in both plant and animal cells?
They are found in BOTH PLANT AND ANIMAL CELLS because they play a major role to keep the whole cell in function!
What is the size difference between eukaryotic and a prokaryotic algae?
in prokaryotes and eukaryotes size doesnt play role.some prokaryotes are larger and even smaller and same case in eukaryotes also.this prokaryotes and eukaryotes division is only based on celluar organization,function and composition not by size
