Question

In oogamous reproduction,

• A. Both male and female gametes are motile
• B. Both gametes are product of division of protoplast
• C. Both male and female gametes are non-motile
• D. For male gametes protoplast divides but for female gamete it does not

Answer 1

The correct option is D For male gametes protoplast divides but for female gamete it does not

• Oogamy is a system of sexual reproduction in which one gamete (called the egg) is large and nonmotile, while the other (called the sperm) is small and motile. Oogamy is a type of Anisogamy.
  
• During Spermatogenesis, the protoplast of spermatogonium is equally divided into 4 spermatids while during oogenesis, ovum retains the bulk of protoplast and is minimally shared by Polar bodies.

So, the correct option is 'For male gametes protoplast divides but for female gamete it does not'.
