“The cell is immortal. It is merely the fluid”

Simplified Meaning:

All living things are made up of tiny parts called cells. Think of a cell like a building block that makes up the body. Cells can live and grow forever if they have the right conditions, kind of like how plants can keep growing if they get enough water and sunlight. However, cells need specific fluids around them to stay alive and function, like how a fish needs water to survive. If the fluid around them changes or becomes harmful, the cells can die or stop working properly. For example, in medical science, researchers have learned how to keep human cells alive for long periods in the lab by providing them with the right nutrients, which are the fluids they need. This idea can also be seen in taking care of our health: if we give our bodies the right nutrients through food and drink, our cells can stay healthy and function well for a long time. It's like making sure your phone always has enough battery; if you keep charging it, it will keep working.
