Damn Near Everything There Is To Know About Cells:
Biology Cell Report
There are many parts of a cell, they all have specific duties, and are all needed to continue the life of the cell. Some cells exist as single-celled organisms that perform all of the organism's metabolism within a single cell.
Such single-celled organisms are called unicellular. Other organisms are made up of many cells, with their cells specialized to perform distinct metabolic functions. One cell within an organism may be adapted for movement, while another cell carries out digestion. The individual cells no longer carry out all life functions, but rather depend on each other. Many-celled organisms are called multicellular. When a group of cells function together

The nucleus contains DNA, the master instructions for building proteins. DNA forms tangles of long strands called chromatin, which is packed into identifiable chromosomes when the cells are ready to reproduce.
Also within the nucleus is the nucleolus, a region that produces tiny cell particles that are involved in protein synthesis These particles, called ribosome's, are the sites where the cell assembles enzymes and other proteins according to directions of the DNA.
Assembly, Transport, and Storage:
Cytoplasm - The material that lies outside the nucleus and surrounds the organelles is the cytoplasm, a clear fluid that is a bit thinner than toothpaste gel. It usually constitutes a little more than half the volume of a typical animal cell.
Endoplasmic Reticulum - The endoplasmic reticulum (ER) is a folded membrane that forms a network of interconnected compartments inside the cell. The ER membranes contain the enzymes for almost all of the cell's lipid synthesis, they serve as the site of lipid synthesis in the cell. The ER functions as the cell's delivery system. Some parts of the ER are studded with ribosome's. In the cell, the sites of protein assembly are the ribosome's.
Golgi Apparatus - The Golgi apparatus's main purpose is to store materials. The
Golgi apparatus is a series of closely stacked, flattened membrane sacs that receives newly synthesized proteins and lipids from the ER and distributes
All cells take in and use nutrients and other substances from the surroundings. Cells of the intestine and the kidney are specialized to carry out
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 endoplasmic reticulum is specialised for protein processing and lipid biosynthesis. One of its primary functions is to regulate the ionic concentration in the cytoplasm via the movement of Ca2+, via ionic pumps and channels. It also contains enzymes responsible for the metabolising of drugs. Endoplasmic reticulum (ER) can come in two forms. As depicted in Fig. 2 Rough ER has ribosomes present as part of the membrane of the organelle, and together with these ribosomes takes polypeptides and amino acids from the cytosol and synthesises proteins destined for attachment to cell membranes. It is in the lumen of the rough ER that the proteins are folded into the specific three dimensional shapes that are so important for biochemical recognition and linking sites [6]. It is called rough because of the presence of ribosomes makes the surface of the membrane look rough, unlike smooth ER, which lacks the ribosomes so the membrane looks smooth. Rough ER is composed of a large but convoluted flattened sac. The main function of the smooth ER is the production of lipids and the metabolism of compounds (such as the breakdown of glycogen into glucose). Because of the different functions between the rough and smooth ER, different specialised cells will have different amounts of each; for example, hepatic
* Cells allow things to go in and out of the organism (allows diffusion to happen so good things go in and bad things go out)

They also create and administer medicines to sick or wounded animals. In a cell, ribosomes are the main source of protein synthesis for the cell. They link different amino acids in a sequence determined by messenger RNA. They also create antibiotics to kill invading viruses in the cell.
One the above date and time Officer Sandula, Officer Johnston and myself went to Cell 8 to move three inmates out of Cell Block 8 that had been causing disturbances throughout the night, inmates; Christopher James Knight (A-13483), Montel Lamar Rice (A-15526) and, Devon Allen Soltysiak (A-15794). The disturbances included throwing food and toilet paper at the walls and ceiling, taking recreation equipment out of designated zones, not wearing full jail attire and clogging the sink by clogging the drain with toilet paper and covering the plug with a bowl of the cell causing flooding. During having the inmates pack up their personal items, inmate Knight said he wanted to go to a holding cell so he could yell through the vents to his wife Melanie Dice Knight (A-15084) and that he had been trying to move for 2 weeks by acting out. Knight then pulled out a tooth brush with one end filed to a sharpened point. He asked to be taken to a holding cell for having a “shank”, I replied no and he was going to another cell for the meantime. Officer Johnston confiscated the toothbrush and I escorted Knight to his new cell, he asked again to be taken to a holding cell but I refused once more so in response he hit the ceiling near a sprinkler head with his mattress. After placing inmate Knight in Cell 5 he wrote a derogatory threatening letter daring to be moved to a Holding Cell. While in cell 5 he left his mattress and property on the community table and complained that he was going to fight with inmate Terrance Walter Newton (A-15144) who he thought was in Cell 5 but was in Cell 3. Officer Johnston, Officer Sandula and I then removed Knight from Cell 5 and put him in holding Cell A. Shortly
P1: Outline the function of the main cells of the body. Cells are the main structure of the body as they all come together to form one cell. They are very important because without them, we wouldn’t be able to live. The cells carry out numerous of chemical reaction that we wouldn’t have heard of or even felt and it is simply done it on its own. Cells make up all the organs in the body.
P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.
Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.
This is the story of a cell, a young cell. This cell’s goal was to have the most powerful mitochondria of any other cell she knew. The mitochondria gave energy. She knew if she had a strong mitochondria, her being would be powerful and strong.
All of these different parts work like organs in a living body, and they are all required and needed to keep the body/organism in a working condition.
Across the planet, four times every second, a new human is conceived. In just nine months, a single cell no bigger than a speck of dust transforms into the most complex organism on earth. There are many events that shape and define us long before we’re born. Right from the start, it’s a journey full of surprises. There are many things that make you who you are today.
Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.
