It's dry stuff until you start putting a biological spin on it. This dry stuff essentially is the means by which organisms have coped with their physical environment. Now of course you know that many plants and many animals are multi-cellular. The question then is, can we create a hypothetical universe for multi-cellular plants.
Unicellular organisms do quite well.
In fact in an aquatic environment, it pays to be small and unicellular in many physiological respects. But, there are advantages to getting larger. One is that you can specialize. That means you only gain two cells in one sexual cycle. Every time you go through sexual reproduction, you create four new individuals by every meiotic cell division.
