Question

In which on of the following would you expect to find glyoxysomes?

• A. Endosperm of wheat
• B. Endosperm of castor
• C. Palisade cells in leaf
• D. Root hairs

Answer 1

The correct option is B Endosperm of castor

Glyoxysomes are microbodies which occur only in fat rich plant cells where they take part in $\beta$-oxidation of fats and perform glyoxylate cycle. Glyoxysomes characteristically possess catalase enzyme. The castor endosperm stores fat which is metabolised through glyoxysomes. Glyoxysomes will channel fats into krebs cycle through $\beta$-oxidation.
