👉 The answer to your question is quite complex, and I'll try my best to explain it with a funny twist.
Imagine that there are two types of trees: the ones we grow on Earth and the ones that we harvest from them. Imagine then that there's a special kind of tree called 'lignocellulosic' (cellulosic, cellulose). This tree is famous for producing lignocellulosic biomass, which is made up of cellulosic fibers like plant material and cellulose. But there's another type of tree, one that we don't usually see. It's called the 'lignocellosar' (cellulose). It doesn't produce much of anything except for lignocellulosic biomass. In fact, it's actually a kind of 'lignocellulosacide', which means it decomposes into simpler sugars like glucose and fructose. Now imagine that this second tree is located on Mars or somewhere else in the solar system, where there might be other ecosystems that are similar to Earth but have different laws governing what plants can do. Perhaps they're able to convert lignocellulosic biomass into a type of cellulose called 'lignocellosar' (cellulose). But wait, there's a problem with this kind of cellulosic economy on Mars or in the solar system. It turns out that these cells are actually living things, like bacteria, fungi, and other microorganisms.
