To survive, a cell must have an original cell to reproduce.
They then need energy to survive. (this can be sugar, meat, sun, water, and others)(they mostly use protein to repair themselves)
They cells need different structured molecules to survive.
If your asking what they have, then they have 3 main features.
They have a fatty membrane, to contain all the other molecules.
They have Cytosol which is a liquid which contains nutrients.
Finally they have DNA or RNA which tells what the cell should do
Cells are the smallest structures of an organism. (nothing simpler than a cell is considered to be alive)
animal cells contain all following structres except a
A unicellular organism must be versatile because it needs to be able to respond and adapt to changes in its environment to survive. With only one cell performing all its functions, it must have the ability to carry out various tasks like obtaining nutrients, reproducing, and defending itself efficiently. Versatility helps the organism thrive in different conditions and compete for resources.
no, there are smaller.
Cells are surrounded by a barrier called a cell membrane and at some point in their lives they contain the molecule that carries biological information (DNA). The structures that all cells have are ribosomes, plasma membrane, cytoplasm, and genetic material.
Ribosomes are the building structures in all cells.
A ribosome is the organelle that builds proteins. Is that what you are looking for? If not, sorry! :(

I actually read (from the Harvard Medical School website) that cancer cells rely on normal, healthy genes and cells as much as they rely on mutated ones. Also, they can only survive if the cell that they are living in is low on oxygen. Just like we need oxygen to survive (that's why we can't survive on Mars, people!!!) cancer cells need low oxygen to survive... Addendum: While irreverently stated, the above author was quite correct. A cancer cell is ultimately has the same needs as any other cell which primarily consist primarily of oxygen and other nutrients delivered by the blood. For this reason, tumors are often associated with angiogenesis (formation of new blood vessels as tumors that are unable to receive adequite nutrients cannot grow).

They must support their own weight.
