Final answer:

Toxins harm fetuses by crossing placental membranes, which are crucial for protecting the fetus from harmful substances.

Toxins can harm a developing fetus by crossing the placental membranes. The placental barrier, consisting of multiple cell layers, plays a crucial role in protecting the fetus from harmful substances in the maternal blood. These toxins, known as teratogens, can include substances like alcohol and drugs that may negatively impact the developing embryo or fetus.
