Question

Consider the statements with respect to fungi :
(a) They show a great diversity in morphology and habitat.
(b) White spots seen on Mustard leaves are due to a saprophytic fungus.
(c) They prefer to grow in cold and humid places.
(d) The cell walls of fungi are composed of chitin and polysaccharides.
Of the above statements :

• A. a and b are correct.
• B. a and d are correct.
• C. a and c are correct.
• D. d and b are correct.
• E. b and c are correct.

Answer 1

Answer: (B)

a and d are correct.

• The organisms in kingdom fungi include mushrooms, yeasts, molds, rusts, smuts, puffballs, truffles, morels, and molds. More than 70,000 species of fungi have been identified. Fungi are cosmopolitan and occur in air, water, soil and on animals and plants. They prefer to grow in warm and humid places. Hence Fungi shows a great diversity in morphology and habitat is a correct statement with respect to fungi.
• The cell walls of fungi are composed of chitin and polysaccharides. Chitin is a polysaccharide due to which the long, fibrous cell walls of the fungus can penetrate plants and animals, for breaking them down and extracting nutrients.
  
• So, the correct answer is 'a and d are correct'.
