Cells need many chemicals, but perhaps you are thinking of DNA.
Your cells need oxygen to turn food into energy, reproduce, and basically perform all of their tasks.
They both need moisture and both produce spores to reproduce.
Bacteria are able to reproduce on their own while viruses need a host to "hijack" so they can reproduce. Bacteria have metabolisms, catabolic and anabolic biochemical reactions going on in their cells all the time. Viruses do not. Bacteria can grow in size to a certain extent while viruses do not change in this regard. The definition of living things classify bacteria as a living thing, while viruses are not.
What are the six needs of living things? You need cells to survive. Some organims are anaerobic and can survive even without the oxygen. The only thing they need are anorganic substances for building their tissues.

Need to repair damaged cells and Increase number of cells
Because the cells themselves need energy to perform their specific function, and to reproduce!
Cells need to reproduce in order to grow, repair damaged tissues, and replace old or dying cells in the body. This process, known as cell division, is essential for the survival and functioning of living organisms.
They are made of cells, they need energy, they reproduce.
nucleic acids
Pathogens that need living cells in order to reproduce are called obligate intracellular parasites. These pathogens rely on a host cell's machinery to replicate and spread throughout the body. Examples include viruses and certain bacteria.
No, an amoeba doesn't need fertilization to reproduce. An amoeba reproduces asexually.
Some creatures are asexual because of their ability to reproduce on their own. Most creatures need intercourse to reproduce but because of cells in their body, that is the thing they don't need.
