• C. The cell wall of fungi are composed of peptidoglycans
• D. Fungi prefer to grow in warm and humid places

Answer 1

The correct option is C The cell wall of fungi are composed of peptidoglycans

The cell wall of fungi is composed of chitin. They prefer to grow in warm and humid places. Hence, fungi show a great diversity in morphology and habitat. Fungi are cosmopolitan and occur in air, water, soil and on animals and plants.

The pathogen, Puccinia is the rust fungus. It is the most prevalent of all the wheat rust diseases, occurring in most wheat-growing regions.

Penicillium mould naturally produces the antibiotic penicillin.

Hence, the incorrect statement is option c.
