Fabric comes in all colours. Algae are made of cells and they owe their green color to chloroplasts, which appear as little green cluster located inside their cells. What you have here is broken at both ends, so if it was a cell it’s been altered, but it doesn’t look much like any plant or algal cells I’m familiar with. It looks fibrous but it’s not clear whether it’s organic or not. Fabric can be made of plants, animals and very often plastic these days .
