The chemical that cells need to reproduce is primarily DNA (deoxyribonucleic acid). DNA contains the genetic instructions crucial for the development, functioning, and reproduction of all living organisms. During cell division, DNA is replicated to ensure that each new cell receives an accurate copy of the genetic material. Additionally, RNA (ribonucleic acid) plays a vital role in translating these genetic instructions into proteins, which are essential for cellular processes.
Cells need many chemicals, but perhaps you are thinking of DNA.
tRNA
yes it does
reproduce.
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.
nucleic acids
They are made of cells, they need energy, they reproduce.
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.
