It contains a dense structure called the Nucleolus and is surrounded by the Nuclear Envelope, a structure composed of two membranes, seperated by fluid, which contain a number of nuclear pores that can allow relatively large molecules through. However, some eukaryotic cells are enucleated cells (without a nucleus), for example, red blood cells (RBCs); whereas, some are multinucleate (consists of two or more nuclei), for example, slime molds. A fluid-filled space or perinuclear space is present between the two layers of a nuclear membrane. Nucleoplasm is the gelatinous substance within the nuclear envelope. The nucleus is separated from the cytoplasm or the rest of the cell by a nuclear membrane. Also asked, how is the structure of the Golgi apparatus related to its function? The nucleolus stores proteins and RNA. Because the nucleus houses an organisms genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information centre of the cell. The nucleus is the most prominent organelle as compared to other cell organelles, which accounts for about 10 percent of the cells volume. extracellular vesicles.

Chromosomes consist ofDNA, which contains heredity information and instructions for cell growth, development, and reproduction. The cell body carries genetic information, maintains the neuron's structure, and provides energy to drive activities. What does the golgi apparatus do in a plant cell? These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. The main difference between nucleolus and nucleus is that nucleolus is a sub-organelle located inside the nucleus whereas nucleus is a membrane-bound organelle in the cell. Also called karyoplasm, this semi-aqueous material is similar to the cytoplasm and is composed mainly of water with dissolved salts, enzymes, and organic molecules suspended within. The nucleolus helps to synthesizeribosomesbytranscribingand assembling ribosomal RNAsubunits. Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function. This membrane seems to be continuous with the endoplasmic reticulum (a membranous network) of the cell and has pores, which probably permit the entrance of large molecules. The mRNA molecules are then transported through the nuclear envelope into the cytoplasm, where they are translated, serving as templates for the synthesis of specific proteins.
