Cellulose is the major component of cell walls of :
A Pseudomonas
B Saccharomyces
C Pythium
D Xanthomonas

Detailed Solution

The cell wall of true fungi is made of chitin (fungal cellulose) and other polysaccharides.
Pythium belongs to the Oomycetes (water moulds), a group traditionally placed in Phycomycetes. Unlike other fungi, the cell wall of oomycetes is mainly made of cellulose and glucans, with little or no chitin.
Pythium causes the damping-off disease of seedlings.
Saccharomyces (yeast) is an ascomycete fungus; its cell wall has glucans, mannans and chitin, not cellulose.
Pseudomonas and Xanthomonas are bacteria; their cell walls are made of peptidoglycan (murein).
So cellulose is the major component of the cell wall of Pythium.
