Explanation:

• Complex media: Contains ingredients like extracts (e.g., yeast extract, beef extract) whose chemical composition is not precisely defined.
• Blood agar: Contains blood, which has components (e.g., various proteins, cells) that are not chemically defined in a precise, pure - compound way.
• Synthetic media: Composed of chemically defined, pure compounds (so it does not have undefined ingredients).
• Chemically defined media: As the name suggests, all components are chemically defined (so it does not have undefined ingredients).
