Nucleus Essay

The function of a nucleus is that it controls nearly all the activities that is taken place in the body. The function of the nucleus is to help control all the activities inside the cell. Also the nucleus controls the cells growth and reproduction. Chromosomes Chromosomes are long threads of DNA and protein seen in a dividing cell. They contain the genetic material or genes.

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.

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 (A20): The structure that the genetic material is stored in. In the center of the cell.

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

The main function of the Endoplasmic Reticulum is to produce, store and transport proteins and lipid to most of the cell organelles. The Endoplasmic Reticulum is a large organelle that looks like sheets of folded membranes.

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 of the nucleus is the nucleolus. This doesn’t have a membrane, but holds itself together. In the nucleolus, ribosomes are created through the mixture of RNA and proteins. These proteins are originally found in the cytoplasm, outside the nucleus, but they travel through the pores in the nuclear envelope, through the chromatin and into the nucleolus. The structure of the nucleolus allows easy

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.)

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.

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

Nucleus: The nucleus controls the cell. like the cork of a baseball controls the trajectory and the direction.

The nucleus is crucial to the function of the cell because it holds instructions on building proteins and that is vital for the function of every part in the cell, but not only that the nucleus uses sends particular information out so that it can be made into protein. The reason that the nucleus has to send out the information out is because the DNA never leaves the nucleus ... say that the cell needs a particular protein for a certain reason, the nucleus will transcrip that information using a molecule called mRNA, and that mRNA will leave the nucleus and will be translated in the cytoplasm by the ribosomes.

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

In regards to their basic structure, according to the SEER Training website, “cells consist of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.” (Training.seer.cancer.gov, 2017) This is true for animal cells however plant cells contain a fourth part which is known as the cell wall, it is located on the outside of the cell membrane and allows the cell to keep its rigid shape. It should also be known that there are types of cells that do not contain a nucleus, these are called prokaryotic cells and generally still have the same characteristics as cells that do have a nucleus which are known as eukaryotic cells. (Study.com, 2017) As seen in Figure 1 cells also contain organelles which keep the cell alive and allow it to function effectively.The cytoplasm of the cell which resides between the cell membrane and the nucleus is a gel-like liquid filling the inside of the cell. The cytoplasm allows the cell to have shape and allows the cell 's organelles to move around the cell as needed and function correctly. The nucleus is widely considered to be the control center or
