Nucleus


The Nucleus is a single rounded structure and it contains the genetic material. It is surrounded by a membrane that protects it from the rest of the cell. It floats within the cytoplasm. The nucleus is the control center of the cell. It controls the activities of the cell by regulating the expression of the genes. You could also say it is like the "brain" of the cell.

Ribosomes are made inside the nucleolus and then sent outside the nucleus to make proteins.
When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains.

Ribosomes floating and on rough endoplasmic reticulum Ribosomes are special because they are found in both prokaryotes and eukaryotes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol.

Ribosomes are found in many places around a eukaryotic cell. You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell. Other ribosomes are found on the endoplasmic reticulum. Endoplasmic reticulum with attached ribosomes is called rough ER. It looks bumpy under a microscope. The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell. There are also ribosomes attached to the nuclear envelope. Those ribosomes synthesize proteins that are released into the perinuclear space.

The eukaryotes are animals, plants, fungi and protoctist. Several individual chromosomes are found within the nucleus, which is a relatively large spherical sac, bound by a nuclear membrane. The prokaryotes are bacteria and cyanobacteria (photosynthetic bacteria). The cells of the prokaryotes have no true nucleus, but contain a single circular strand of DNA…
