Explain Why A Nucleus Is Crucial To The Function Of A Cell

Essentially, the nucleus is vital for the cell’s survival. The nucleus controls and gives instructions to all organelles and inhabitants of the cell(Doc. 2). It is a dense, ball shaped configuration that contains the DNA of the cell.

Structure and Function of Eukaryotic Cell Organelles What are eukaryotic and prokaryotic cells? Organelles in Eukaryotic Cells The Nucleus. Nearly all animal cells have a nucleus, with the only exception being the red blood cell. The nucleus has two major functions, which are housing the DNA and controlling the cell’s activities. In the centre

Technical Jargon 1. An atomic particle is like a cell and nucleus is the control center of the cell. The nucleus is where the mass of the atom and all of its subatomic particles is concentrated.

The nucleolus is one of the most important organelles. This organelle is a eukaryotic cell. The nucleolus is not like most of the other organelles. Most other organelles have a static structure but the nucleolus does not. The structural components are chains of RNA and DNA. It contains granular and fibrillar components.

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

Nucleus [pic] The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and

• The nucleus is enclosed in a nuclear membrane which has pores to allow RNA and proteins. The nucleus functions the activity in a plant cell and stores the plant’s DNA. (Plant Cell Anatomy, n.d.)

For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.

• Cell Division (A80): One of the phases of the cell cycle. Mitosis and Cytokinesis. • Nucleus (A20): The structure that the genetic material is stored in. In the center of the cell.

A Cell is like a City A cell membrane regulates what enters and leaves the cell. It is like a gate in a city because it regulates who comes in and goes out of the city. A nucleus is the control center of the cell. It is like a police department because the police control how everyone and everything acts. A ribosome synthesizes proteins for the cell. A ribosome is like a factory that produces stuff for construction workers. The ER synthesizes lipid membranes and proteins and transports stuff. It is like a manufacturing plant because it makes stuff just like the ER.

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

Nucleus – The nucleus envelope is filled with fluid in which chromatin can be found. There are the ribosome-studded double membranes. Chromatin consists of DNA and proteins’. Within the cell nucleus is a viscous liquid called nucleoplasm. The nucleus acts as a control centre for the cell, directing and controlling the activities within the cell (Toole, G; Toole, S 2004; Wikipediea, 2016).

The nucleus contains chromosomes in which the DNA encodes proteins. The mRNA molecules transcribed from the DNA leave through the nuclear pores in the nuclear envelope to attach to free ribosomes or ribosomes on the rough Endoplasmic Reticulum (rER). mRNA molecules try to bind to ribosomes as they contain ribosomal RNA (rRNA) transcribed from DNA in the nucleolus. The attachment of mRNA allows protein synthesis to occur at the ribosome, producing proteins in their primary structure. These polypeptide chains then travel through the rER where they are packaged and pinched off into little vesicles and carried to the Golgi complex. They are then chemically modified and folded into newly synthesised proteins which can then leave the cell (exocytosis) through secretory vesicles produced at the Golgi complex.

the nucleus is a membrane-enclosed organelle found in most eukaryotic cells. Though the nucleus is called the “control center”, it is not always located in the center of the cell. It is true that the nucleus may or may not be in the center but it will never be on the edge of the membrane. It is also the largest organelle in any cell and contains most of the cell's genetic information. The genetic information is found encoded in DNA in the form of genes. Genes are short segments of DNA that contain information to encode an RNA molecule or a protein strand. RNA is the messenger molecule made from DNA that delivers instructions from the nucleus to the cytoplasm. DNA in the nucleus is organized in long linear strands that are attached to different

Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a
