What are the two types of fertilization in plants?

Of these three, porogamy is most common..

What is the first step in fertilization?

Summary. The fertilization process begins when spermatozoa are released from the male and enter into the oocyte’s environment (external fertilization) or are deposited into the female (internal fertilization) and it ends when the zygote is formed.
