Question

multiple choice question
in angiosperms, fertilization does not require water because sperm, the male gametes, are
o formed within the female gametophyte.
o anchored to the ground.
o transported by the xylem.
o transferred in pollen.

Explanation:

In angiosperms, pollen grains (which contain the male gametes - sperm) are transferred to the female reproductive part (stigma) through various agents like wind, insects etc. This transfer does not require water. Xylem is for water and mineral transport in plants, not for sperm transfer. Sperm are not formed within the female gametophyte (they are formed in the anther within pollen grains). And being anchored to the ground has no relation to fertilization not requiring water.

Answer:

transferred in pollen.
