Question

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

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

Answer 1

The correct option is B Endosperm of castor

• The endosperm of castor (castor bean is oil producing plant) contains glyoxysomes.
• Glyoxysomes are a type of peroxisomes found in plants and few filamentous fungi.
  
• They are particularly found in fat storage tissues of germinating seeds (peanuts, soybeans etc.) in plants.
  
• They contain enzymes (citrate synthase, isocitrate lyase and malate synthase etc.) which are responsible for beta-oxidation of fatty acids,
  
• It helps in fatty acid oxidation, glyoxylate cycle and gluconeogenesis.
  
• So, the correct answer is 'Endosperm of castor'.
