  • Correct answer
    B

  • C
    formation of seeds with syngamy but no meiosis
  • D
    none of the above.

Solution

Amphimixis is normal type of sexual reproduction having both meiosis and fertilization. But in some plants, the normal sexual reproduction is replaced by some abnormal type of sexual reproduction where there is no meiosis and syngamy. It is of two types vegetative reproduction and agamospermy. In vegetative reproduction plants develop from parts other than seeds. In agamospermy, plants produce seeds as means of propagation by abnormal method.
