Answer
The sperm needs to swim in order to move towards the egg for fertilization. This movement is crucial because the sperm must reach the egg, which is often located in a different area of the reproductive system. In many species, sperm are released into the female reproductive tract, and their motility is essential for successfully navigating this environment to complete the process of fertilization.

Answer
Fertilization occurs in the fallopian tube (also known as the oviduct) of mammals. In plants, fertilization typically takes place in the ovary, specifically within the ovule, where the sperm meets the egg to form a zygote.
