Asked in Premeth past paper pool — Biology

The option which characterises apomixis in the flowering plants is

Correct answer: D. D

  • A. Option A
  • B. Option B
  • C. Option C
  • D. D

Explanation

In apomixis, meiosis is either skipped or modified, and the MMC or other cells within the ovule divide mitotically to produce a diploid embryo sac. Apomixis is a form of asexual reproduction in plants where seeds are formed without fertilization. So option D is correct. All other options give wrong combinations.

About Embryonic Development

Embryonic development begins after fertilization with cleavage and formation of the morula and blastula, followed by gastrulation and the establishment of germ layers. It includes organ formation, tissue differentiation and early growth, rather than the later increase in size associated with postnatal development.
