Final answer:
Cello bags primarily consist of cellulose, which makes up 92-98% of their composition, with the remainder potentially consisting of binding agents, plasticizers, or fillers to enhance their properties.
Step-by-step explanation:
You are correct that cello bags are primarily made of cellulose, but they may indeed contain additional components aside from cellulose. Cellulose is a natural biopolymer found in plant cell walls and is indeed the most abundant organic compound on Earth. As you've mentioned, the composition of cello bags can be 92-98% cellulose.
This means that there could be a small percentage of other substances included, such as binding agents, plasticizers, or fillers, which are used to enhance the bag's properties, such as flexibility, strength, or clarity. These additional compounds help to adapt the cellulosic material to its intended use while maintaining the desired properties of the cello bag, such as being semi-transparent and durable.
