The cell wall of oomycetes is chiefly composed of___________?

Correct answer: B. Cellulose

  • A. Chitin
  • B. Cellulose
  • C. Lignin
  • D. Proteins

Explanation

The cell walls of oomycetes are chiefly made of cellulose and other glucans, unlike true fungi, whose walls are mainly chitin. Students may choose chitin because oomycetes were historically called water moulds and treated as fungi, but their wall composition helps distinguish them from true fungi.
