Why We Study the Cell and Its Components The cell is the most basic form of life essentially. Anything that is living fundamentally is composed of cells. We study the cell because it is the simplest unit of all living organisms and to begin understanding life‚ we must realize the cell’s structure‚ whether it is about the different types of cells or how the cell functions. Biology is the study of life and for the human species; the cell is the most basic principle of life‚ which is why it is so

P1 [pic] Cell membrane - encloses the contents of the cell and regulates the flow of substances into and out of the cell. Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells. Centriole - these two features made of hollow tubules play a key role in cell division. Ribosomes - these small‚ granular features of the cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the

Why we study literature‚ and its influence on the 21st century. Man has for many centuries‚ used literature as a medium to express his thoughts‚ to educate and inform the masses‚ and literature has been used as a textual tool for pleasure. With the coming and strong influences of the ‘Technological New Age’‚ the fundamentals of literature (reading to educate oneself) have been side tracked to make way for mass media and giant companies that produce technological gadgets such as cellular phones

Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the biggest part of the cell and is the part of the cell which acts like the brain. It is not always in the middle of the cell but will be placed within the cytoplasm. In some cases a cell may have many nuclei and these are

Biology – Assignment One Cells. Question One Explain the roles of the main components and features of a cell to the cell function. A typical animal cell is rounded in shape‚ surrounded by a cell membrane. This holds in the cytoplasm‚ which contains other structures such as the nucleus‚ ribosomes‚ and mitochondria. Each cell has tiny structures inside called organelles; each type of organelle performs a particular function. For example there are mitochondria (power stations)‚ ribosomes (protein

ASSIGNMENT - Why is a cell microscopic? By Lachlan Bryant This research assignment will discuss why cells are usually microscopic in size‚ given that they need to be able to exchange material with their surrounding environment. The cell is highly organised with many functional units or organelles (Spurger).A membrane is a fluid mosaic which consists of proteins‚ lipids and carbohydrates which seperates the cell from it’s surrounding environment or subdivides a cell into specialised regions or
