Question

Which function of tapetum is correct?

• A. Helps in pollen wall formation
• B. Transportation of nutrients to inner side of anther
• C. Synthesis of callase enzyme for separation of microspore tetrads
• D. All of these

Answer 1

The correct option is D All of these

• Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat.
  
• Secretion of the enzyme callase (β-1,3- glucanase) to dissolve the callosic wall of the tetrad and set them free.
  
• Formation of the pollen wall during the postmeiotic period.
  
• So, the correct option is 'All of these'.
