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 xanthophylls 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

The correct option is A (i) and (ii)

In the given structure of the fungal cell.

• A represents the cell wall. Fungal cell wall contains chitin along with other polysaccharides, proteins, etc. Chitin is a mucopolysaccharide and is also present in the exoskeleton of insects and arthropods.
• B represents the reserve food material vesicles that store food in the form of glycogen and oils.
• C represents mitochondrion. Fungi are achlorophyllous organisms and lack chloroplasts and photosynthetic pigments
• D represents the nucleus. Septate hyphae may be uni-or multi-nucleate and aseptate hyphae are usually multinucleate (= coenocytic).

Thus, Statement (I) and (ii) are correct.
So, the correct answer is (A).
