Which one of the following is true for fungi?

  1. They lack a rigid cell wall.
  2. They are heterotrophs.
  3. They lack nuclear membrane.
  4. They are phagotrophs.

Answer

(2) They are heterotrophs.

Solution

As per NCERT, fungi are heterotrophic organisms: most are saprophytes (absorbing soluble organic matter from dead substrates), some are parasites and some live as symbionts.

∵ Fungi have a rigid cell wall of chitin and polysaccharides, are eukaryotic (nuclear membrane present) and take food by absorption, not by phagocytosis, options (1), (3) and (4) are false.

Answer: (2)
