Which one of the following is INCORRECT about double fertilization in angiosperms?

Options

  1. ASyngamy is the fusion of haploid male and female gametes to form a diploid zygote.
  2. BTriple fusion involves the fusion of a haploid male gamete with a diploid secondary nucleus.
  3. CBoth syngamy and triple fusion are generative fertilization.
  4. DBoth the male gametes participate in double fertilization.

Correct answer

C. Both syngamy and triple fusion are generative fertilization.

Step-by-step solution

Double fertilization in angiosperms involves two types of fusions: syngamy and triple fusion. Syngamy is the fusion of one haploid male gamete with the haploid egg cell to form a diploid zygote. This process is known as generative fertilization. Triple fusion is the fusion of the second haploid male gamete with the diploid secondary nucleus (formed by the fusion of two polar nuclei) to form a triploid primary endosperm nucleus (PEN). This process is known as vegetative fertilization. Since triple fusion is vegetati
