Which of the following is a common name for cell membrane disruptors?

Cell membrane disruptors are herbicides that target and impair the cellular structure of plants, causing cell contents to leak and ultimately leading to plant death. Diquat is a well-known example of a cell membrane disruptor, specifically used as a desiccant and herbicide. It operates by damaging the membranes of plant cells, which results in the loss of essential cellular functions and can quickly kill unwanted vegetation.

Other options listed do not fit this definition. Bipyridylium refers to a class of compounds, with diquat being a specific example—so while diquat belongs to this class, it is the one that effectively disrupts cell membranes. Glyphosate, on the other hand, works by inhibiting specific enzymes in the shikimic acid pathway, making it a systemic herbicide rather than a cell membrane disruptor. Trifluralin is a pre-emergent herbicide that primarily acts by inhibiting seed germination and root development, rather than directly targeting the cell membranes of plants. This understanding of how these herbicides function clarifies why diquat is correctly identified as a common name among cell membrane disruptors.
