You're close! While nylon, starch, and cellulose are all important materials, they are formed through different processes. Here's a breakdown:

* Nylon: Nylon is a synthetic polymer, meaning it's created by humans using chemical reactions. It's not naturally occurring.

* Starch: Starch is a carbohydrate found naturally in plants. It's formed through photosynthesis, the process where plants convert sunlight, water, and carbon dioxide into energy and carbohydrates.

* Cellulose: Cellulose is another carbohydrate that is the primary structural component of plant cell walls. Like starch, it is formed through photosynthesis.

So, while nylon is a product of human ingenuity, starch and cellulose are the results of biological processes.
