Downy mildew is caused by what type of organism?

Explanation:
Downy mildew is caused by water molds, a group of organism known as oomycetes. These fungus‑like microbes thrive in moist conditions and produce a fluffy, downy growth on the undersides of leaves. They are not bacteria, not viruses, and not true fungi—hence the best description is a water mold rather than any of the other options. This distinction matters because downy mildew behaves and spreads like oomycetes, different from true fungi like powdery mildew.
