Answer» SOLUTION :Fertilization : The process of two similar or dissimilar gametes is called as syngamy as a result diploid zygote is formed. There are two types of fertilization. EXTERNAL fertilization : In this type of fertilization, syngamy occurs outside the body of organism. Example - in most aquatic organisms LIKE algae, FISH, amphibians. The major disadvantage of external fertilization is they PRODUCE a large number of offsprings but the offsprings are vulnerable to predators. Internal fertilization : ..Syngamy occurs inside the body of organism. Example - fungi, birds, mammals. Male gametes are released close to the female gametes where they fuses to form zygote. |
