Why apples turn brown after you slice them?

When you cut an apple, oxygen in the air touches parts of the apple's cells. This starts a chemical reaction that makes the apple turn brown. It's a natural process!

⭐ Bonus fact: Adding lemon juice to apple slices can help stop them from turning brown.
