As the pH of a solution increases, deprotonation of the acidic and basic groups on proteins occur,
so that carboxyl groups are converted to carboxylate anions (R-COOH to R-COO-) and ammonium groups are converted to amino groups (R-NH3+<span> to R-NH</span>2<span>).
In proteins the iso-electric point (pI) is defined as the pH at which a protein has no net charge.
When the pH > pI, a protein has a net negative charge and when the pH < pI, a protein has a net positive charge.
The pI varies for different proteins.</span>

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.
