Answer:
Nitrogen fixation
Explanation:
Certain soil bacteria, e.g., <em>Azobacter spp</em> can combine free nitrogen of the atmosphere with oxygen to form nitrates. This is called <u>nitrogen fixation</u>. Other nitrogen-fixing bacteria such as Rhizobium form symbiotic unions with the roots of leguminous plants called root nodules. They fix nitrogen to form nitrates which are used up by the host plant. Nitrifying soil bacteria, e.g., <em>Nitrobacter </em>convert nitrites to nitrates in a process called <u>nitrification</u>.

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.
