The Structure Of Eukaryotic Cells

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.

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 – 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

Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm. In eukaryotic cells the chromosomes remain together inside the nucleus and there is a clear nuclear membrane that is surrounding 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 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.)

The nucleus is vital in the animal cell but in a plant cell it is most assuredly the chloroplasts.

The human body is made up of trillions of cells and each cell has a nucleus, filled inside with chromosomes made of a long string of DNA (deoxyribonucleic acid) wrapped around a special protein called histone (American cancer society 2014). According to Cancer Research UK (2014) DNA by itself is made up of thousands of genes, which are a coded message that tell the cell how to behave and divide. As such if the signals are missing, cells replicate excessively and mutate, forming a tumour, and later, a primary cancer (American cancer society 2014).

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.

The nucleus in eukaryotic cells contains the DNA in linear chromosomes and is bounded by a nuclear membrane, but since

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
