The phenomenon of single or double fertilization is unique to the seed plants

Biology

Ksju [112]3 years ago

Answer:

Double fertilization

Explanation:

The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.

Depending on the context that the explanation is being used in or who is reading it, the explanation may be interpreted in two completely different manners which may be far off from the original intended explanation. This can therefore completely nullify or maybe even expand the original determination.
