Your friend asks for your help checking their essay about sugar production and use in plants. They have found an online encyclopedia stating that plants produce glucose via photosynthesis.
Glucose is linked together to form the carbohydrate starch. They are confused, though, because
a university website states that glucose is linked together to form cellulose, the main part of
plant cell walls.

In 3–5 sentences, describe how you can help your friend check their information and how both
statements can be true.
