Question

Identify the incorrect statement with respect to angiosperms.

• A. Megasporophyll is commonly woody
• B. Ovules are borne on a stalk or a funiculus
  
• C. Archegonia are absent
  
• D. Embryo is a post fertilisation structure
  

Answer 1

The correct option is A Megasporophyll is commonly woody

The archegonium is a female reproductive organ in bryophytes and some gymnosperms but not found in angiosperms.
Megasporophyll is the female reproductive organ in gymnosperms in heterosporous plants i.e. producing two types of spores - megaspores or microspores. The sporangia producing the spores are found on leaf-like structures called sporophyll. The sporophyll bearing megasporangia is called megasporophyll and the sporophyll bearing microsporangia is called microsporophyll. The megasporophyll of a gymnosperm is woody. Megasporophyll in an angiosperm is rolled to produce a carpel, which is delicate.

Ovules in the carpel of an angiosperm are connected to the wall of the ovary bya stalk-like structure called funiculus.
The haploid male and haploid female gametes of the angiosperm fuse to form a diploid zygote. This event is called syngamy or fertilisation.The diploid zygote undergoes mitosis to develop into an embryo which happens only after fertilization (post fertilization).
