Proteins In The Cell Membrane
4,687 wordsCells are the basic living units of all plants and animals. The cell is the structural and functional unit of all living organisms. There are a wide variety of cell types, such as nerve, muscle, bone, fat, and blood cells. Each cell type has many characteristics, which are important to the normal function of the body as a whole. One of the important reasons for maintaining hemostasis is to keep the trillions of cells that form the body functioning normally. An averaged size cell is one-fifth the...

Cell Cytoplasm By A Membranous Nuclear Envelope
3,398 wordsThe cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a...

Function Of The Cell Membrane
1,313 wordsIn every part of our body there reigns a tiny yet complex life. An examination under the microscope into the depths of any human organ brings us face to face with an astounding miracle of creation: millions of tiny living things that have come together to make up that organ are engaged in arduous activity. These tiny beings are cells, the basic units of life. Not only man but also all other living things are composed of these microscopic living beings. There are about 100 trillion cells in the h...
