Question

Angiosperms and gymnosperm resemble in having

• A. Vessel in wood
• B. Mode of fertilization
• C. Siphonogamy
• D. Nature of endosperm

Answer 1

Answer: (C)

Siphonogamy

Siphonogamy is the mode of reproduction in which non-motile male nuclei are carried to the egg cell through a pollen tube. It is found in all angiosperms and most gymnosperms. It has enabled these plants to reduce their dependency on wet conditions for reproduction, unlike the zoidogamous plants in which the male gametes (antherozoids) swim in a film of water to reach the female gametes.Thus the correct answer is option C.
