Detailed explanation-1: -Independent single-celled organisms must conduct all the basic processes of life: it must take in nutrients (energy capture), excrete wastes, detect and respond to its environment, move, breathe, grow, and reproduce.
Detailed explanation-2: -The one cell of a unicellular organism must be able to perform all the functions necessary for life. These functions include metabolism, homeostasis and reproduction.
Detailed explanation-3: -Since all cells need to produce ATP, all cells need glucose which is a nutrient. In summary, cells need ions (to keep concentration gradients), oxygen and various nutrients (such as glucose).
Detailed explanation-4: -Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.
