Cell (biology) The cell (from Latin cella, meaning small room) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Enclosing the cell is the cell envelope – generally consisting of a cell wall covering a plasma membrane though some bacteria also have a further covering layer called a capsule. 2  The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter.

- Medical Definition of Cell. Cell: The basic structural and functional unit of any living thing. Each cell is a small container of chemicals and water wrapped in a membrane. There are 100 trillion cells in a human, and each contains all of the genetic information necessary to manufacture a human being. This information is encoded within the cell nucleus in 6 billion subunits of DNA called base pairs.

- In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

cell In biology, a cell is the basic unit of life. Your body is made up of millions of cells, and they come in all different kinds. Each type of cell serves a specific function, but they all have a very similar structure. Each cell has a cell membrane, which surrounds the cell and protects the inner components.ytoplasm is the fluid that fills cells and serves several important functions. Cytoplasm holds the internal components of cells in place and protects them from damage. Cytoplasm stores molecules used for cellular processes, as well as hosts many of these processes within the cell itself.

What is a cell? It means that biologists can work on a cell from a mouse and be reasonably certain that the same processes will occur in a similar cell in a lion, a human or a fruit fly. This is possible because all cells are thought to have arisen from a common ancestor. Many different types of plant and animal cells have evolved.

What is a Muscle Cell? A muscle cell is a special kind of cell that makes up an organism's muscle tissues. The muscles allow independent movement and regulate biological functions such as digestion and heartbeat. These cells are further specialized into distinct types based on their location and functions.

Who coined the word cell ? Cell (biology) Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100 trillion cells; a typical cell size is 10 µm, a typical cell mass 1 nanogram). The largest known cell is an ostrich egg.

cell 1. The basic unit of living matter in all organisms, consisting of protoplasm enclosed within a cell membrane. All cells except bacterial cells have a distinct nucleus that contains the cell's DNA as well as other structures like mitochondria and the endoplasmic reticulum.ll cells are bounded by a cell membrane; plant cells have an outer cell wall in addition. 4. (Biology) biology any small cavity or area, such as the cavity containing pollen in an anther.

cell in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes.he size of the nucleolus is a function chiefly of the cell’s ribosome requirement; the nucleolus is, therefore, especially large in a cell that intensively synthesizes proteins. Protein synthesis, the end result of chromosome function, occurs mainly in the cytoplasm.

Welcome visitors! Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.

- Cell Biology Cell biology is the science of studying how cells function such as their reproduction metabolism, and their internal and external anatomy. Biology means science … of life. Cells are known as the basic building blocks of all livings things. More Information Cell biology (also called cellular biology or formerly cytology, from the Greek kytos, container) is an academic discipline that studies cells.

Cell (biology) Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Organisms can be classified as unicellular (consisting of a single cell; including bacteria) or multicellular (including plants and animals). While the number of cells in plants and animals varies from species to species, humans contain more than 10 trillion (1013) cells. Most plant and animal cells are visible only under a microscope, with dimensions between 1 and 100 micrometres.

Studying Cells Cells as Building Blocks. A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Cell group The cell group is a form of church organization that is used in some Christian churches.Cell groups are generally intended to teach the Bible and personalize Christian fellowship.he term cell group is derived from biology: the cell is the basic unit of life in a body. In a metaphorical sense, just as a body is made up of many cells that give it life, the cell church is made of cell groups that give it life.

Cell Biology/Print version Cells are structural units that make up plants and animals; also, there are many single celled organisms. What all living cells have in common is that they are small 'sacks' composed mostly of water. The 'sacks' are made from a phospholipid bilayer membrane. This membrane is semi-permeable (allowing some things to pass in or out of the cell while blocking others).
