Why Do Organelles Carry Out Its Function

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.

One of the main manufacturing facilities within a cell. Consists of rough ER and smooth ER, they are physically connected but differ in structure. Consist of membrane-enclosed tubes and sacs within the cytoplasm. Rough ER, named for the ribosomes attached to its surface, make membrane and secretory proteins. One function of rough ER is to produce new membrane. Some products by rough ER are dispatched to other locations by transport vesicles.

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

They are very important in the synthesis and packaging of proteins. Some of those proteins might be used in the cell and some are sent out. The ribosomes are attached to the membrane of the ER. As the ribosomes builds the amino acid chain, the chain is pushed into the ER. When the protein is complete, the rough ER pinches off a vesicle. That vesicle, a small membrane bubble, can move to the cell membrane or the Golgi apparatus

The ER makes lipids, breaks down and packages proteins for the Golgi complex. The Golgi Complex processes and transports and proteins out the cell. (Nnpdf.org, 2016)

Nucleus- which is an organelle is found eukaryotic cells. The nucleus is the control point of the cell which helps control movement, eating, reproduction and also contains genetic material. The nucleus and the other organelles are surrounded by the nuclear envelope; it is similar to the cell membrane. The nucleus contains something called chromatin which is made of RNA, DNA and nuclear proteins. DNA contains genetic material and also instructions to how to make our body work properly. DNA is tied up by chromosomes. As the DNA cannot travel outside the nucleus to give instructions, it makes a smaller copy of it self which is known as RNA. The RNA which does travel from the nucleus then gets read by the ribosomes, which then proceeds on to make proteins. The main function of the nucleus is to control gene expression and to help the replication of DNA which takes place during the cell cycle.

The nucleus, commonly known as the brain, is the command center of eukaryotic cells. This membrane bound organelle carries information and instructions, in the form of DNA packed into chromatin, for growth, development, and reproduction to all other organelles. The nucleus oversees the all activities in the cell. Without a nucleus, the organelles of the cell would not know what to do.

DNA occupies most of the remaining space inside a nucleus. DNA is inborn material that has the direction or the command to build proteins. Proteins are helping with most activity in the cells. Our DNA is arranged or structured in a systemic way into about 20,500 genes, basically instruction manuals for our bodies. Without all of these genes, our body would not be able to make proteins. Proteins are very necessary to make sure that everything in your body is working properly. The nucleus helps the cell to protect the very important DNA. More importantly, the nuclear envelope keeps your genes separate from the other things inside the cells. The things that make a eukaryotic cell are a defined nucleus. The nuclear envelope surrounded the nucleus and all of its materials. The nuclear envelope is like a membrane similar to the cell membrane around the cell. There are pores and spaces for RNA and proteins to pass through while the nuclear envelope keeps all of the chromatin and nucleolus

Neurones - are nerve cells. They carry information as tiny electrical signals. There are three different types of neurones, each with a slightly different function. Sensory neurones carry signals from receptors to the spinal cord and brain. Relay neurones carry messages from one part of the CNS to another. Motor neurones carry signals from the CNS to effectors.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

Proteins serve a myriad of functions whether within or outside of the cells. These functions include structural roles (cytoskeleton), transport of

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

The nucleus of eukaryotic cells is usually takes up between 10-20% of the cell volume, and it’s primary function is to protect the genetic material stored as linear, often diploid chromosomes, as well as the production of ribosome subunits (Brooker et al, 2014). The majority of the cells genetic material is stored in the nucleus which is surrounded the double membraned nuclear envelope, while extra genetic material is stored within mitochondria and chloroplasts so they have the ability to replicate independently of the cells. The double membrane is made up of a phospholipid bilayer which links to the rough endoplasmic reticulum in the cytoplasm, which consists of cytosol (the site of metabolic pathways) and the other
