Which toxin category is associated with toxins produced by plants?

• A. Mycotoxins
• B. Bacterial
• C. Algal
• D. Plant

Answer: (D)

Origin of toxins by source is what this question tests. Toxins produced by plants are categorized as plant toxins, so identifying the plant as the source makes it the best answer. This helps distinguish them from toxins produced by other organisms: mycotoxins come from fungi, bacterial toxins come from bacteria, and algal toxins come from algae. Examples of plant toxins include ricin from castor beans and solanine from certain nightshade plants, which illustrate toxins that plants themselves produce rather than microbes or algae.
