Question

Match the storage products listed under column I with the organism given under column II. choose the appropriate option from the given options:
$\begin{array}{cc}ColumnI& ColumnII\\ A.Glycogen& 1.Sargassum\\ B.Pyrenoids& 2.Nostoc\\ C.Laminarinandmannitol& 3.Polysiphonia\\ D.Florideanstarch& 4.Spirogyra\\ & 5.Agaricus\end{array}$

• A. A-3, B-4, C-1, D-5
• B. A-4, B-3, C-5, D-2
• C. A-5, B-4, C-1, D-3
• D. A-2, B-1, C-4, D-3

Answer 1

The correct option is C A-5, B-4, C-1, D-3

Glycogen is the storage product of fungi. Agaricus, commonly called the button mushroom, is a fungus and hence its storage product is glycogen. Pyrenoids are commonly seen in green algae (Spirogyra). Laminarin and mannitol are produced in brown algae (Sargassum). Floridean starch is the type of storage product seen in red algae (an example is Polysiphonia). Hence, the correct match is given in pption c.

$\begin{array}{cc}A.Glycogen& 5.Agaricus\\ B.Pyrenoids& 4.Spirogyra\\ C.Laminarinandmannitol& 1.Sargassum\\ D.Florideanstarch& 3.Polysiphonia\end{array}$

Note: The storage product of Nostoc is cyanophycean starch.
