These ribosomes are called the cell organelles that are made up of proteins and RNA and proteins. The nucleoplasm contains the cells genetic material. It is connected to the endoplasmic reticulum (ER) in such a way that the internal chamber of the nuclear envelope is continuous with the lumen, or inside, of the ER. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. Endoplasmic Reticulum Function. Function: Chromosomes contain the genetic information (DNA) of the It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other important functions. The golgi is made of 5-8 folds called cisternae. The genetic materials relate all the functions of the cells. Nucleoplasm also supports the nucleus by helping to maintain its shape. nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane.
