Question

The diagram shows the structure of a fungal cell with different parts labelled as $A,B,C$ and $D$. Which of the following statements are true with regard to the fungal cell structure?

(i) A contains mucopolysaccharides which are also present in exoskeleton of insects and crustaceans.
(ii) D are usually more than one in number in case of aseptate hyphae.
(iii) Carotenes and xanthopnylls are present in $C$, which harvest light energy for photosynthesis.
(iv) $B$ is the reserve food material, usually stored in the form of starch and oil.

• A. (i) and (ii)
• B. (iii) and (iv)
• C. (i), (ii) and (iv)
• D. (ii), (iii) and (iv)

Answer 1

Answer: (A)

In the given structure of fungal cell, A is the cell wall. Fungal cell wall contains chitin along with other polysaccharides, proteins, etc. Chitin is a mucopolysaccharide and is also present in exoskeleton of insects and arthropods. In fungi, the reserve food material is present in the form of glycogen (shown by $B$) and oils. $C$ represents mitochondrion. Fungi are achlorophyllous organisms and lack chloroplasts and photosynthetic pigments. $D$ represents nucleus. Septate hyphae may be uni-or mutli-nudeate and aseptate hyphae are usually multinudeate (= coenocytic).
