The correct answer is Micropyle.

The micropyle can be defined as opening in the ovum that allows the pollen to enter into it for the process of fertilization. In gymnosperm the pollen is drawn into the ovule on a drop of fluid that comes out of the micropyle, called as pollination drop mechanism. Micropyle is  present in gymnosperm and absent in pteridophytes.

While some substances/molecules move through diffusion by moving with the concentration gradient (as in the case of passive transport, others move against the concentration gradient requiring energy to cause the transportation (as in the case of active transport).
