EVERYONE KNOWS THAT WE R MADE OF CELLS.HOW R INDIVIDUAL CELLS ATTACHED TOGETHER,WHY DONT THEY JUST SCATTER OFf

Cells have what is called an extracellular matrix, which includes proteins that anchor everything togteher (things like collagen and elastin, etc.).

In animals and plants, cells are the smallest units that can be considered alive. Your body, like all human bodies, is a collection of many many cells. Nearly all cells have the same basic parts - a nucleus, which has DNA, and a cell membrane, which acts as sort of a skin for the cell, keeping insides in, and outsides out. \n\nCells are arranged together to form tissues, which in turn arrange together to form organs, which fit together to form systems (like the digestive system), which in turn all keep you as one functioning living being!\n\nMost cells in a large organism like plants and animals have specialized purposes as well - some are nerve cells, transmitting signals to and from the brain to the rest of the body, some are in your blood, carrying oxygen to the rest of the body, some form your skin, keeping you from getting infected from outside. \n\nCells have their own lifespans, and can reproduce and die.\nSometimes, a mutation happens in cells, and they don't follow their genetic instructions and might grow and reproduce abnormally -- this is what cancer is.

It is the simplest form of a cell membrane. Actually the cell on contain es the cell membrane and nothing else. It is used for research when doing tests on a cell membrane. It has nothing that could interfere with normals.

Cells are usually not flat.  They are flattened when we prepare them for optical microscope slides.  There have been plenty of electron microscope pictures of various cells from the human body -- a good example would be the donut-shaped red blood cell, which is definitely not flat.

Mature human RBC have no nucleus.\n\nMuscle cells have several, as a result of cells fusing together.

Well.. cells were first discovered by a man by the name Robert Hooke in 1663. He made the first microscope and saw MANY types of cells. Then two or three individuals formed the cell theory into three man parts.\n\nOne was Matthias Schleiden...another...Theodor Schwann .\n\nThe three basic parts to the cell theory are:\n1. Cells are the basic unit of all living things.\n2. Every living thing has one or morecells.\n3. All cells come from other cells.\n\nGlad to help\n\n~LG23~

Every part has its own work to play in out body. Even a dead cell becomes Nails and saves our finger muscles.

All human tissue and body parts are made of cells. They are the building blocks of all living creatures.

A virus needs a cell to replicate itself. You see viruses have absolutely no ability to reproduce on there own. They basically "hijack" a cell and then the cell makes a copy of the virus.

They are called eukaryotic cells.

Your body makes cells by the process called mitosis.\n\nHere's a website on mitosis:\nhttp://www.cellsalive.com/mitosis.htm

The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." 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 or 1014 cells; a typical cell size is 10 µm, a typical cell mass 1 nanogram).\n\nThe cell theory, first developed in 1839 by Schleiden and Schwann, states that all organisms are composed of one or more cells; all cells come from preexisting cells; all vital functions of an organism occur within cells, and cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.\n\nThe word cell comes from the Latin cella, a small room. The name was chosen by Robert Hooke when he compared the cork cells he saw to the small rooms monks lived in.\n\nAll cells, whether prokaryotic or eukaryotic, have a membrane, which envelopes the cell, separates its interior from its environment, regulates what moves in and out, and maintains the electric potential of the cell. Inside the membrane, a salty cytoplasm takes up most of the cell volume. All cells possess DNA, the hereditary material of genes, and RNA, containing the information necessary to build various proteins such as enzymes, the cell's primary machinery. There are also other kinds of biomolecules in cells.

My first thought, is organs.\n\nBut let me look.\n\nNope, I was wrong they form together to form tissue.  The building block of all of us.

Being single celled. They have some of the most complex cells because their cells have to do all the work - as opposed to multicellular animals which have division of labour.

Cells have different shape to allow them to work better. For example, the alveoli cells are flat and big in surface, these features helps in gas exchange.

You are using the word organism incorrectly. the body is made up of billions of interconnected, interdependent cells. A single cell from the body cannot survive on its own once removed from the body. There are however single cell organisms that live within the human body but are not a part of it and are seen for the most part as hostile by the bodies immune system...while others such as those found in yogurt cultures are extremely beneficial to the human body but are still not a part of it.
