Introduction to Human Biology.
The purpose of this paper is to discuss how the human cell works and the components within it, including details on mitosis and its process, the importance of DNA and chromosomes, how they work and protein synthesis. I will then look at the effect of neoplasm on the cell and all the consequences that it has. This will include factors such as growth, symptoms and prevention. Then I will research possible treatment for a particular neoplasm, which will be cancer of the skin.
Every cell performs many different tasks to survive and consists of many organelles which all have their own part to play in the function of the cell. Endoplasmic reticulum is a network of tubes mainly used for protein synthesis and breaking down toxins, there are two types of endoplasmic reticulum: smooth and rough, it is known as rough because it has ribosomes attached to it.
Ribosomes are made of protein and nucleic acid and every second in every animal cell one million amino acids are added to growing proteins, the ribosome can be attached to the endoplasmic reticulum or they can be free particles in the cytoplasm. Golgi bodies are the modification of endoplasmic reticulum and are responsible for packing proteins ready for export from the cell, it's made up of around six flat discs and the vesticles it produces may be exported from the cell. The cell membrane protects the rest of the cell and is permeable which allows things to move in and out of the cell, it is a bi-layer structure consisting of lipids and proteins. Lysosome is the modification of Golgi; they literally eat things which disturb the natural order of the cell. Mitochondria are also inside the cell and are very important because it is the power station...
