Parasitic fungi absorb nutrients directly from the living host cytoplasm with the help of special hyphal tips called___________?
Correct answer: C. Haustoria
- A. Mildew
- B. Constricting ring
- C. Haustoria
- D. All of these
Explanation
Haustoria are specialized hyphal projections that enter or grow against host cells and absorb nutrients from living plant tissue. Students may choose mildew because it is associated with parasitic fungi, but mildew is a fungal growth or disease, not a nutrient-absorbing hyphal tip.

The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
