Unit 5 P1 the Functions of the Main Cell Components of the...

In this report i will be writing brief description on the functions of the main cell components of the body cell. The cell membrane : is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It is composed of a thin, double-layered sheet of lipids, around the Cell and is a protective membrane layer around every Cell. Nucleus [pic] The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cells growth and†¦show more content†¦It acts as a storage organelle. It is important in the creation and storage of steroids. It also stores ions in solution that the cell may need at a later time. Steroids are a type of ringed organic molecule used for many purposes in an organism. They are not always about building muscle mass like a weight lifter. The ion storage is important because sometimes a cell needs ions fast. It might not want to search the environment for ions, so it is easier to have them stored in a pack for easy use. Rough ER - looks rough on the surface because it is stubbed with very small organelles called ribosomes. Ribosomes are made of RNA and protein and are the site of protein synthesis. 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 Golgi apparatus[pic] The function of the Golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell. Lysosome [pic] Lysosomes are single, membrane-bound sacs that containShow MoreRelatedAssignment Brief to Break Down Unit 5 Health and Social Care Level 11545 Words   |  7 PagesBTEC Extended Diploma Level 3 Assignment Brief Course Title: Extended Diploma Level 3 in Health and Social Care Unit : 5 Assignment Title: Anatomy Physiology Scenario/Vocational Context: This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism.
