All living cells are like that of working machines. They constantly need inputs like nutrients, e.g, glucose, amino acids, minerals, water, and oxygen etc. All these undergo various biological interactions to bring about the cellular functions. These interations are called as Metabolism. In multicellular animals the blood works as transporting agency. It transports various above said componants to the cells. In turn the cells produce waste and excretory products like CO2 etc as a result of metabolism called as out puts. These outputs are again picked up by blood and transported to various organs for their expulsion to the exterior.

All cells need for life are nutrients, water and a way to dispose of waste. Blood is a multi cellular fluid which facillitates the movement of these components in a large complex animal. Viruses and Bacteria dont have blood as most of these are smaller tahn the cells cotained in the blood. No plants have blood either and consist of many varied and complex cells

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.
According to recent studies made by World Bank, the coming crisis will be far worse than initially predicted. So if you're already preparing for the crisis (or haven't started yet) make sure you watch this video at http://www.familysurvival.tv and discover the 4 BIG issues you'll have to deal with when the crisis hits, and how to solve them fast (before the disaster strikes your town!) without spending $1,000s on overrated items and useless survival books.

I would agree with the first response. Cells need nutrients, oxygen, and water. I would also add that cells need a way to get rid of waste products. Blood provides a medium for the delivery of the aforementioned items.

Cells need oxygen and nutrients to survive. Not all cells need blood--only those that are part of a complex multicellular organism does. They do not have access to oxygen or nutrients without blood.

Cells need **pay attention in class** to survive. And cells need blood because **that way you'll actually know the answer yourself**.
