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 structive?

(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 reverse food material, usually stored in the form of starch and oil.

Options

A. i and ii
B. iii and iv
C. i,ii and iv
D. ii,iii and iv

Answer

A

Explanation

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 multi-nucleate and aseptate hyphae are usually multinucleate (= coenocytic).
