15 points. Which of the following best summarizes the process of fertilization of a gymnosperm?
A) Male and female gametes are produced in a single cone, with pollen on the outside and the egg within the ovule beneath the scales. Pollen travels to the ovule, meets the egg, and fertilization can take place.
B) Cones are released from the tree and carried by wind to a moist environment where sperm can easily travel to the egg, and fertilization can take place.
C) Pollen travels from a male cone, the pollen becomes enclosed in the ovule that contains the egg within the female cone, the scale encloses the entire structure, and fertilization takes place.
D) Scales from male cones are carried to female cones, pollen is transferred to the female egg within the ovule, and fertilization takes place.
