List three activities of a cell that help it live
Answer:
1. The use of ATP, also known as the enegy currency of the cell. Cellular functions need ATP to survive.
2. Cell division. Cells need to reproduce for repairing tisues, healing, and more.
3. Active and passive transport. This is important to control what gets in and out of the cell. The selectively permeable membrane is responsible for this process.

Metabolism, respiration, and reproduction are essential activities that help a cell to live and carry out its functions.
What help cells live?Cells have several mechanisms that help them live and carry out their functions. Metabolism, which involves the chemical reactions that occur within a cell, provides the energy and raw materials necessary for life processes. Respiration, the process of converting glucose and oxygen into ATP, also provides energy for the cell.
Cells also have various organelles, such as mitochondria, lysosomes, and ribosomes, that perform specific functions, including energy production, waste removal, and protein synthesis. Additionally, cells have the ability to respond to their environment, adapt to changing conditions, and reproduce to maintain their population.
Furthermore, the genetic material in cells provides instructions for all cellular processes and plays a critical role in the development and maintenance of an organism. In summary, cells have several mechanisms and processes that help them live, function, and contribute to the overall health and survival of the organism.
