Question

Which of the following is correctly matched?

• A. Tapetum --- Mechanical support
• B. Endothecium --- Pollen nourishment
• C. Synergids --- Filiform apparatus
• D. Antipodals --- Male gamete production

Hint:

Filiform apparatus is a distinctive feature of synergids and assists pollen tube entry.

Answer 1

The Correct Option is C

Different structures in flowering plants perform specialized reproductive functions. Tapetum:
• It is the innermost layer of the anther wall.
• It provides nourishment to developing pollen grains.
• It secretes enzymes and sporopollenin precursors. Thus, tapetum does not provide mechanical support. Hence option (A) is incorrect. Endothecium:
• It lies below the epidermis.
• It develops fibrous thickenings.
• It helps in anther dehiscence. Therefore, endothecium is not responsible for pollen nourishment. Hence option (B) is incorrect. Synergids:
• They are part of the egg apparatus.
• They possess specialized wall ingrowths called filiform apparatus.
• They help in guiding the pollen tube. Thus, option (C) is correctly matched. Antipodals:
• They are located at the chalazal end of embryo sac.
• They mainly perform nutritive functions.
• They are not involved in male gamete production. Hence option (D) is incorrect. Therefore: \[ \boxed{\text{(C)}} \]
