Which one of the following is wrong for fungi?
(1) They are eukaryotic
(2) All fungi possess a purely cellulosic cell wall
(3) They are heterotrophic
(4) They are both unicellular and multicellular
(2) In fungi, cell wall contains chitin or cellulose along with other polysaccharides, proteins and lipids. Only in some fungi, e.g. Phytophthora or other oomycetes a purely cellulosic cell wall is present. Hence, only option (b) is wrong, rest of the options are correct.
Concept Enhancer Chitin is chemically N-acetyl glucosamine. The exoskeleton of insects also contains this chemical.
