Pollination and fertilization are essentially the same process. If pollination occurs, fertilization will follow quickly.
Answer the following statement true (T) or false (F)
False
Pollination and fertilization are different processes that may be separated by a long delay. Pollination is the mechanical transfer of pollen from its source to a receptive area on the receiving plant. Sperm are subsequently conducted to the egg by a pollen tube, and fertilization-the joining of sperm with egg-may occur much later. For instance, in a typical pine tree, fertilization follows 15 months after pollination.
